87
00:00:46.000 --> 00:00:52.000
coordinator for that office in
Washington DC. He has

88
00:00:52.000 --> 00:01:01.000
coordination to ensure accuracy
in reporting human exposure

89
00:01:01.000 --> 00:01:06.000
on NPL sites to the public and
also we will be joined by John

90
00:01:06.000 --> 00:01:12.000
Burchette, by the lead office,
physical scientist, and he has

91
00:01:12.000 --> 00:01:18.000

00:01:18.000 --> 00:01:24.000
as an environmental consultant
and John has worked

93
00:01:24.000 --> 00:01:30.000
overseeing NPL, or BRAC,

94
00:01:30.000 --> 00:01:36.067
facility sites before joining
the

95
00:01:36.067 --> 00:01:42.000
FFRRO office here. Lastly joined

96
00:01:42.000 --> 00:01:48.000
by Jim Sferra, Ohio EPA, worked
in the private

97
00:01:48.000 --> 00:01:54.000
consulting center, at Ohio EPA,
worked

98
00:01:54.000 --> 00:01:58.000
as a hazardous waste

99
00:01:58.000 --> 00:02:01.000
exposure and other management
positions.

100
00:02:01.000 --> 00:02:09.000
Is a chief in the Southeast
District,

101
00:02:09.000 --> 00:02:13.000
coordinated all of Ohio EPA
divisions as well as overseeing
numerous

102
00:02:13.000 --> 00:02:19.000
positions come with action
programs and Brownfields. With

103
00:02:19.000 --> 00:02:24.000
that brief introduction we will
call up opening material about
the

104
00:02:24.000 --> 00:02:30.000
seminar series, I will turn it
over to Emmy to provide
background

105
00:02:30.000 --> 00:02:36.067
information in the series. I
just want to talk

106
00:02:36.067 --> 00:02:42.000
about the facilities Academy,
develop for

107
00:02:42.000 --> 00:02:47.000
other project managers and
government, tribal

108
00:02:47.000 --> 00:02:53.000
groups that work on Superfund
cleanups at the sites, really to

109
00:02:53.000 --> 00:02:58.000
help supplement other EPA
trainings that may not

110
00:02:58.000 --> 00:03:02.000
focus specifically on the
nuances in the federal facility
cleanup

111
00:03:02.000 --> 00:03:07.000
we hope these 11 webinars can
shed more light on the
challenges

112
00:03:07.000 --> 00:03:12.000
we face. And also one date in
person course getting
rescheduled with

113
00:03:12.000 --> 00:03:17.000
everything currently going on
hopefully we will have new dates
going on

114
00:03:17.000 --> 00:03:23.000
soon of the of variability of
that course. Really geared to
help

115
00:03:23.000 --> 00:03:33.000
you voluntary, and helped to
hone in on the facilities at the
site.

116
00:03:33.000 --> 00:03:36.000
>> Thank you Emmy.

117
00:03:36.000 --> 00:03:40.934
>> Just a quick reminder. In
terms of participation

118
00:03:40.934 --> 00:03:44.934
and in credit, as Emmy was
highlighting the entire series
of course is 11

119
00:03:44.934 --> 00:03:49.934
online webinars in one in person
classroom delivery.

120
00:03:49.934 --> 00:03:55.934
The 11 online webinars are open
to the public. They can be taken

121
00:03:55.934 --> 00:04:00.934
online life, and replayed on
demand. Regardless of

122
00:04:00.934 --> 00:04:06.934
how you participate with online
webinars, you

123
00:04:06.934 --> 00:04:10.934
can provide a certificate for
each session in the series upon
feedback.

124
00:04:10.934 --> 00:04:15.934
If you are live you can get a
certificate

125
00:04:15.934 --> 00:04:19.934
come if you replay you can still
get a certificate, mix-and-match

126
00:04:19.934 --> 00:04:25.934
your participation through any
live or replay of the recorded
versions.

127
00:04:25.934 --> 00:04:29.934
In classroom delivery, that you
will attend

128
00:04:29.934 --> 00:04:35.000
in person as Emmy mentioned,
they are rescheduling that
delivery.

129
00:04:35.000 --> 00:04:39.000
If you would like to get Academy
certificate documenting and all

130
00:04:39.000 --> 00:04:43.000
of the webinars as well as the
in person delivery, you will
need to

131
00:04:43.000 --> 00:04:49.000
complete online sessions have
certificates for all 11 webinars
and attend the

132
00:04:49.000 --> 00:04:54.000
in person classroom training to
get the Academy certificate,

133
00:04:54.000 --> 00:04:59.000
this will have a limited
audience not open to the general

134
00:04:59.000 --> 00:05:05.000
public EPA dates, tribes and
other federal agencies. We will

135
00:05:05.000 --> 00:05:10.000
share details as they become
available for that classroom
training.

136
00:05:10.000 --> 00:05:14.000
With that brief introduction
Emmy, let's call

137
00:05:14.000 --> 00:05:18.000
it the presentation materials
and get started with the
session.

138
00:05:18.000 --> 00:05:23.000
>> I apologize we will get you
to the starting slide.

139
00:05:23.000 --> 00:05:25.000
>> Great while that is loading
up.

140
00:05:25.000 --> 00:05:31.067
I want to say thank you for
joining us today, looking at
performance

141
00:05:31.067 --> 00:05:37.067
measures and environmental
indicators not only just for
federal facility

142
00:05:37.067 --> 00:05:44.000
sites. A lot of what we will
discuss today

143
00:05:44.000 --> 00:05:48.000
applies to Superfund cleanup,
we're excited to bring this to
you today.

144
00:05:48.000 --> 00:05:54.000
Before the content, we want to
get a better idea,

145
00:05:54.000 --> 00:06:00.000
a group Poll, to

146
00:06:00.000 --> 00:06:04.000
get an idea of your experience
and where

147
00:06:04.000 --> 00:06:10.000
you're coming from, Jean can you
lead the group through the

148
00:06:10.000 --> 00:06:12.000
Poll?

149
00:06:12.000 --> 00:06:16.000
>> Absolutely there is a dialog
box where you can enter

150
00:06:16.000 --> 00:06:21.000
your own response to the
question, what experience if any
have you

151
00:06:21.000 --> 00:06:27.000
had with determining EI at
facility site?

152
00:06:27.000 --> 00:06:33.067
Enter your answer hit send, upon

153
00:06:33.067 --> 00:06:36.067
other answers come you will see
them cue

154
00:06:36.067 --> 00:06:39.000
up in the window above, review
what others enter and agree or
vote if

155
00:06:39.000 --> 00:06:44.000
you are sharing those
experiences browse through
others

156
00:06:44.000 --> 00:06:47.000
and what they submit, if you
find something ring entry on
your end

157
00:06:47.000 --> 00:06:50.000
in my case, I have no
experience.

158
00:06:50.000 --> 00:06:56.000
You can Hoover your question
answer over that

159
00:06:56.000 --> 00:07:02.000
answer, click +12 agree with the
entry, the list

160
00:07:02.000 --> 00:07:04.000
will populate.

161
00:07:04.000 --> 00:07:09.000
I could see already it looks
like a lot of people have very
limited

162
00:07:09.000 --> 00:07:14.000
or no experience with this at
all. Some

163
00:07:14.000 --> 00:07:17.000
have multiple years.

164
00:07:17.000 --> 00:07:23.000
They are season veterans working
with environmental

165
00:07:23.000 --> 00:07:28.000
indicators, these answers are
sorting themselves up the bulk
of the audience

166
00:07:28.000 --> 00:07:31.067
has little experience in this
arena.

167
00:07:31.067 --> 00:07:36.067
>> Okay I'm actually not
surprised to hear the response.

168
00:07:36.067 --> 00:07:40.000
There are all in here

169
00:07:40.000 --> 00:07:46.000
a lot of people who have limited
experience, usually it would be

170
00:07:46.000 --> 00:07:51.000
done internal to EPA come I
didn't participate

171
00:07:51.000 --> 00:07:55.000
with other federal agencies, I
would go through the flowchart

172
00:07:55.000 --> 00:07:56.000
we will discuss later today.

173
00:07:56.000 --> 00:08:01.000
Make the determination and
submit into that

174
00:08:01.000 --> 00:08:06.000
appropriate database into
collection for EPA overall
tracking.

175
00:08:06.000 --> 00:08:11.000
Hearing people say I haven't
been exposed to this. I can
totally see

176
00:08:11.000 --> 00:08:15.000
that. I'm hoping once you learn
and

177
00:08:15.000 --> 00:08:18.000
what we have in today's webinar
and the opportunity to engage in

178
00:08:18.000 --> 00:08:22.000
conversations with your site
team, you will be better
prepared to discuss

179
00:08:22.000 --> 00:08:26.000
those topics. Particularly if
there is a challenging

180
00:08:26.000 --> 00:08:29.000
situation emerging that your
site.

181
00:08:29.000 --> 00:08:37.067
Thank you for a little of other
ideas of who we are dealing with

182
00:08:37.067 --> 00:08:42.000
on the phone is a helpful thing.
Now I will hand

183
00:08:42.000 --> 00:08:47.000
it over to get started with
slide content.

184
00:08:47.000 --> 00:08:51.000
>> On the screen you can see the
top over

185
00:08:51.000 --> 00:08:55.000
the course of the presentation I
will kick it off with
performance

186
00:08:55.000 --> 00:09:00.000
measures and targets
environmental indicators and
other

187
00:09:00.000 --> 00:09:06.000
CERCLA components and guides and
tools. Slide 4.

188
00:09:06.000 --> 00:09:12.000
performance measures. Again I
will kick things that

189
00:09:12.000 --> 00:09:17.000
there I've been doing it for
five years

190
00:09:17.000 --> 00:09:23.000
previously I was in the region
for seven years. Next

191
00:09:23.000 --> 00:09:25.000
slide.

192
00:09:25.000 --> 00:09:28.000
It looks like it went too far.

193
00:09:28.000 --> 00:09:33.067
In this section of the webinar I
will discuss the government or
performance

194
00:09:33.067 --> 00:09:39.000
and result act, GPRA, and touch
on

195
00:09:39.000 --> 00:09:44.000
performance management and
environmental indicators before

196
00:09:44.000 --> 00:09:50.000
we get into a more in-depth
discussion about EI's.

197
00:09:50.000 --> 00:09:56.000
What is GPRA?

198
00:09:56.000 --> 00:10:01.000
These goals align with annual
plans and budgets,

199
00:10:01.000 --> 00:10:07.000
and reporting outcomes through
the multi-year agency

200
00:10:07.000 --> 00:10:12.000
strategic plans, some of the key
components of GPRA are the

201
00:10:12.000 --> 00:10:18.000
five-year strategic plans,
annual reporting of the
successions

202
00:10:18.000 --> 00:10:24.000
and meeting targets. Last thing
GPRA was modernized by

203
00:10:24.000 --> 00:10:30.000
the government performance
modernization act,

204
00:10:30.000 --> 00:10:36.067
the performance being tracked in
the EPA

205
00:10:36.067 --> 00:10:39.000
annual plan and budget.

206
00:10:39.000 --> 00:10:44.000
The primary game for this goal,

207
00:10:44.000 --> 00:10:50.000
to provide strategic plans. EPA
strategic plan published every

208
00:10:50.000 --> 00:10:56.000
four years describing the a
traveler,

209
00:10:56.000 --> 00:11:05.000
and these to achieve them,
environment and land

210
00:11:05.000 --> 00:11:08.000
and preventing contamination.

211
00:11:08.000 --> 00:11:14.000
Superfund remedial program
tracks six measures reported to
Congress,

212
00:11:14.000 --> 00:11:19.000
one of the key measure, why it's
important they are linked

213
00:11:19.000 --> 00:11:24.000
to how much money is needed to
complete the work.

214
00:11:24.000 --> 00:11:29.000
We complete these annually
through the congressional
justification

215
00:11:29.000 --> 00:11:38.000
or [Indiscernible].

216
00:11:38.000 --> 00:11:42.000
What are these?

217
00:11:42.000 --> 00:11:48.000
>> I will police up on

218
00:11:48.000 --> 00:11:54.000
the screen for you to see.

219
00:11:54.000 --> 00:11:59.000
-- The to environmental
indicators

220
00:11:59.000 --> 00:12:05.000
we will talk in depth later on
the one thing I want to point
out for

221
00:12:05.000 --> 00:12:11.000
federal facilities, for those of
you

222
00:12:11.000 --> 00:12:16.000
who will be familiar with the
program if you're not many of
these facilities

223
00:12:16.000 --> 00:12:21.000
are large installation 50 acres
plus in many,

224
00:12:21.000 --> 00:12:27.000
if you have just one of those 30
or so operable

225
00:12:27.000 --> 00:12:33.067
units where exposure is not
controlled that entire facility
will be listed

226
00:12:33.067 --> 00:12:36.067
human exposure not controlled.

227
00:12:36.067 --> 00:12:41.000
That generally applies to
construction completions SWRAU
and

228
00:12:41.000 --> 00:12:47.000
ground water migration as well.

229
00:12:47.000 --> 00:12:53.000
EPA planning information is
tracked in the Superfund

230
00:12:53.000 --> 00:12:57.000
enterprise management system,
those of you who have been the

231
00:12:57.000 --> 00:13:06.000
agency for a while you may
remember this, and replaced in
2012 or

232
00:13:06.000 --> 00:13:12.000
so, it's a data warehouse where
we are planning out our CERCLA

233
00:13:12.000 --> 00:13:18.000
pipeline, your RDs, or A's,
five-year reviews,

234
00:13:18.000 --> 00:13:24.000
one thing I want to point out, I
know

235
00:13:24.000 --> 00:13:29.000
SEMS and tracking the info isn't
the fun part of the

236
00:13:29.000 --> 00:13:37.934
job as an RPM, this is, people

237
00:13:37.934 --> 00:13:43.934
look at this and plan these
sites to completion the best

238
00:13:43.934 --> 00:13:52.934
we can.

239
00:13:52.934 --> 00:13:58.934
We use the Superfund system to
do that. Some

240
00:13:58.934 --> 00:14:04.934
of these coming up through the
environmental management system
or the super

241
00:14:04.934 --> 00:14:08.934
force task force -- Superfund
task force,

242
00:14:08.934 --> 00:14:14.934
those who are not showing
subsistent progress to site
completions

243
00:14:14.934 --> 00:14:19.934
to determine any site where
human exposure is not

244
00:14:19.934 --> 00:14:23.934
under human control and bringing
those site under control, the

245
00:14:23.934 --> 00:14:28.934
federal facility national
program does have those listed

246
00:14:28.934 --> 00:14:35.000
if they are not controlled, and
several human exposure

247
00:14:35.000 --> 00:14:37.067
data sites.

248
00:14:37.067 --> 00:14:42.000
The folks that are familiar with
the program many of you know,
emergent

249
00:14:42.000 --> 00:14:47.000
contaminants, they can present a
challenge to the program, we
have

250
00:14:47.000 --> 00:14:53.000
ran into challenges with respect
to these

251
00:14:53.000 --> 00:14:59.000
environmental indicators.

252
00:14:59.000 --> 00:15:04.000
In response to the task force
recommendation publicly

253
00:15:04.000 --> 00:15:09.000
accessible EI dashboard was
launched in

254
00:15:09.000 --> 00:15:15.000
2018. both background
information on the

255
00:15:15.000 --> 00:15:21.000
ATEI, the information

256
00:15:21.000 --> 00:15:30.000
is dashboard is both private
facilities

257
00:15:30.000 --> 00:15:34.067
and Superfund sites, here is the
screenshot. It presents
information

258
00:15:34.067 --> 00:15:42.000
from the site name, HE status
and the status description,

259
00:15:42.000 --> 00:15:48.000
these are developed by the rpm's
and uploaded to

260
00:15:48.000 --> 00:15:53.000
SEMS, one thing I want to point
out. I talk about the number

261
00:15:53.000 --> 00:15:56.000
of units and the facility site,
it's

262
00:15:56.000 --> 00:16:00.000
really important that folks
utilize these descriptions,

263
00:16:00.000 --> 00:16:06.000
to highlight what is going on at
the site. Again,

264
00:16:06.000 --> 00:16:12.000
if you have 30 operable units at
your site human exposure is
controlled

265
00:16:12.000 --> 00:16:18.000
at 29 of them, this is an
opportunity to highlight,

266
00:16:18.000 --> 00:16:23.000
29 of those units are under
control. However you do

267
00:16:23.000 --> 00:16:28.000
have one where groundwater
migration is causing

268
00:16:28.000 --> 00:16:34.067
off-base issue come utilize
these to really get your

269
00:16:34.067 --> 00:16:40.000
story out. This information is
available to the public.

270
00:16:40.000 --> 00:16:45.000
With that I will take any
questions.

271
00:16:45.000 --> 00:16:49.000
If there are no questions, I
will kick it over to Jim, to go
over

272
00:16:49.000 --> 00:16:52.000
environmental indicators.

273
00:16:52.000 --> 00:16:58.000
>> I will remind the audience
you can submit questions using

274
00:16:58.000 --> 00:17:01.000
Q&A window at any point.

275
00:17:01.000 --> 00:17:04.000
John, I don't see any in the
queue, perhaps in the interest
of time

276
00:17:04.000 --> 00:17:09.000
will move on if any questions
come, we can come back in

277
00:17:09.000 --> 00:17:12.000
a later segment.

278
00:17:12.000 --> 00:17:18.000
>> Thank you Amy this is Jim
with the Ohio EPA

279
00:17:18.000 --> 00:17:24.000
Jim Sferra, I will

280
00:17:24.000 --> 00:17:29.000
run on with the slides -- Sorry

281
00:17:29.000 --> 00:17:32.067
my slide just disappeared. Okay.

282
00:17:32.067 --> 00:17:38.000
If someone can click the slide

283
00:17:38.000 --> 00:17:42.000
when indicated. I will give a
perspective on environmental
indicators and

284
00:17:42.000 --> 00:17:48.000
their use. Particularly to the

285
00:17:48.000 --> 00:17:53.000
2020 goals. Before I get into
the slides I do have

286
00:17:53.000 --> 00:17:59.000
I want to talk about the
facility, remedy

287
00:17:59.000 --> 00:18:03.000
selection track, these regions,
three and seven,

288
00:18:03.000 --> 00:18:09.000
two figure out why
investigations, to remedy
selection take so long

289
00:18:09.000 --> 00:18:13.000
and retro action, we follow
where in the state the region

290
00:18:13.000 --> 00:18:19.000
come the first lien event as
well, our Ohio data

291
00:18:19.000 --> 00:18:25.000
matched up with three and seven
timeframe. In Ohio, correction

292
00:18:25.000 --> 00:18:30.000
action time frame, this meat and
potato was

293
00:18:30.000 --> 00:18:33.067
under 15 to 20 years.

294
00:18:33.067 --> 00:18:37.067
Some cases took a lot longer.
Few cases we were able to get
through

295
00:18:37.067 --> 00:18:42.000
in relatively short time, still
15

296
00:18:42.000 --> 00:18:48.000
to 20 years is a fair amount of
time to Q remedy

297
00:18:48.000 --> 00:18:54.000
selection. This acronym that it
comes out to,

298
00:18:54.000 --> 00:19:00.000
pretty much in what took so long
in these three impediments

299
00:19:00.000 --> 00:19:06.000
to the progress. Correction, for
the is

300
00:19:06.000 --> 00:19:10.000
lack of common goals, I'm
talking about

301
00:19:10.000 --> 00:19:16.000
issues at the lower level not
those that dispute resolution

302
00:19:16.000 --> 00:19:20.000
I'm talking about field level
decision

303
00:19:20.000 --> 00:19:26.000
sometimes they get strung out a
little longer than they
otherwise

304
00:19:26.000 --> 00:19:32.067
would, if not for elevating them
up the chain.

305
00:19:32.067 --> 00:19:38.000
The third main impediment,

306
00:19:38.000 --> 00:19:42.000
we can certainly work at the
first two at the state level,
common goals

307
00:19:42.000 --> 00:19:48.000
and issue elevation, money is
always a challenge with these
correct

308
00:19:48.000 --> 00:19:56.000
action sites, and CERCLA sites
as well, we recommend

309
00:19:56.000 --> 00:20:01.000
the RCRA with success, those
concepts fit

310
00:20:01.000 --> 00:20:05.000
in nicely. With the
environmental indicator goals

311
00:20:05.000 --> 00:20:11.000
that came about. With the GPA of

312
00:20:11.000 --> 00:20:14.000
1993.

313
00:20:14.000 --> 00:20:16.000
Next slide please.

314
00:20:16.000 --> 00:20:22.000
Environmental indicators
designed to communicate
progress,

315
00:20:22.000 --> 00:20:27.000
and human health in the
environment,

316
00:20:27.000 --> 00:20:30.000
we got to one selection each
year.

317
00:20:30.000 --> 00:20:37.067
We are making progress wrong --
Along the way

318
00:20:37.067 --> 00:20:41.000
>> The focus on these two human
health exposures,

319
00:20:41.000 --> 00:20:47.000
and contaminated groundwater
migration under control. Again
stated previously.

320
00:20:47.000 --> 00:20:52.000
These are sitewide measures, we
want to see

321
00:20:52.000 --> 00:20:58.000
both of those goals in the

322
00:20:58.000 --> 00:21:01.000
EI.

323
00:21:01.000 --> 00:21:04.000
Slide 16 please.

324
00:21:04.000 --> 00:21:10.000
This proceeded number of years
speculated, at

325
00:21:10.000 --> 00:21:15.000
the time frame, around the
selection, and was just a long

326
00:21:15.000 --> 00:21:19.000
time. And progress is being
made, how are you able

327
00:21:19.000 --> 00:21:25.000
to document the changes to the
site are being

328
00:21:25.000 --> 00:21:28.000
conducted.

329
00:21:28.000 --> 00:21:33.067
Meeting these goals was a way to
demonstrate progress at

330
00:21:33.067 --> 00:21:39.000
these high priority sites in
many cases, the years were off.

331
00:21:39.000 --> 00:21:44.000
In Ohio, we are federal
delegated state for this
program,

332
00:21:44.000 --> 00:21:49.000
for these goals for RCRA can

333
00:21:49.000 --> 00:21:55.000
there you could see became our
goals at the state level. With
these

334
00:21:55.000 --> 00:22:00.000
goals it did focus us, and
increase the sense

335
00:22:00.000 --> 00:22:04.000
of urgency and accountability.

336
00:22:04.000 --> 00:22:07.000
At the state and the regulated
entities, not always, but I
think it did provide

337
00:22:07.000 --> 00:22:13.000
a compass point that we would
direct some of the work.

338
00:22:13.000 --> 00:22:19.000
Aim towards accomplishments
where seems things

339
00:22:19.000 --> 00:22:21.000
could be very far off.

340
00:22:21.000 --> 00:22:25.000
We took it to heart to meet
these goals, and spark
cooperation to

341
00:22:25.000 --> 00:22:32.067
meet the goals, some
corporations wanted to show
progress and be

342
00:22:32.067 --> 00:22:36.067
able to say yes, we are meeting
those environmental indicators
slide

343
00:22:36.067 --> 00:22:42.000
17 please. How did we get these?
These list of

344
00:22:42.000 --> 00:22:48.000
sites for the GPRA 2020 that we
were

345
00:22:48.000 --> 00:22:53.000
focused on in RCRA, in 1991.
USEPA ranked

346
00:22:53.000 --> 00:22:59.000
facilities established a
baseline of projects for GPRA.

347
00:22:59.000 --> 00:23:05.000
Back in 91. they ranked all RCRA

348
00:23:05.000 --> 00:23:11.000
sites based on contaminated
media, surface water,

349
00:23:11.000 --> 00:23:16.000
air, and from that ranking they
chose sites for the

350
00:23:16.000 --> 00:23:20.000
baseline for the environmental
indicators. Probably

351
00:23:20.000 --> 00:23:25.000
if you hit and miss on the
baseline. We were allowed

352
00:23:25.000 --> 00:23:33.000
to make a few changes along the
way. US EPA did not.

353
00:23:33.000 --> 00:23:36.000
Easy sites for the 2020
baseline.

354
00:23:36.000 --> 00:23:38.934
Slide 18 please.

355
00:23:38.934 --> 00:23:44.934
The RCRA corrective action
program, the

356
00:23:44.934 --> 00:23:50.934
20 18th, we found the
accomplishments

357
00:23:50.934 --> 00:23:56.934
-- The 2018 accomplishments
shown online, about

358
00:23:56.934 --> 00:24:02.934
3800 on the GPA nationwide
baseline, 95%

359
00:24:02.934 --> 00:24:08.934
met under control, 89% met

360
00:24:08.934 --> 00:24:14.934
migration of contaminated
groundwater under control, 70%
met final remedy

361
00:24:14.934 --> 00:24:18.934
construction and 36% met
performance standards attained.

362
00:24:18.934 --> 00:24:24.934
How did we do? I think overall

363
00:24:24.934 --> 00:24:29.934
we did pretty good. Ohio numbers
matched up fairly close.

364
00:24:29.934 --> 00:24:36.000
With the national numbers I
think we are at 90%, right

365
00:24:36.000 --> 00:24:40.000
around 90% human health
exposures under control,
groundwater

366
00:24:40.000 --> 00:24:46.000
under control, we had close to
180 site on our

367
00:24:46.000 --> 00:24:58.000
GPA 2020.

368
00:24:58.000 --> 00:25:04.000
It did spur that action we are
in

369
00:25:04.000 --> 00:25:10.000
discussion with Region 5. beyond
2020 here in Ohio. EPA has

370
00:25:10.000 --> 00:25:16.000
recently RCRA, not recently but,
focused on ready

371
00:25:16.000 --> 00:25:17.000
for use.

372
00:25:17.000 --> 00:25:22.000
Another marker for documenting
progress at the site. Slide 19
please.

373
00:25:22.000 --> 00:25:28.000
We do have guidance linked

374
00:25:28.000 --> 00:25:34.067
in the notes section in this
presentation. I want to

375
00:25:34.067 --> 00:25:38.000
close out my part of this
discussion saying,

376
00:25:38.000 --> 00:25:45.000
I was a skeptic at the onset of
this path we went down, we did

377
00:25:45.000 --> 00:25:50.000
keep at it, we saw few site
benefits, one I think you will
hear me say

378
00:25:50.000 --> 00:25:56.000
a lot. Agency and industry
engagement, people started to
talk

379
00:25:56.000 --> 00:26:00.000
to one another, I think
relationships were built.

380
00:26:00.000 --> 00:26:04.000
I think that was one of the
biggest things that came out of
this. Where

381
00:26:04.000 --> 00:26:09.000
we weren't talking, because we
didn't have interim goals, at
the various

382
00:26:09.000 --> 00:26:15.000
steps of this process, it gave
us a reason to

383
00:26:15.000 --> 00:26:21.000
talk and keep things moving. 2.
Air Force

384
00:26:21.000 --> 00:26:25.000
-- Focused on common goals. At
the start of

385
00:26:25.000 --> 00:26:31.067
my discussion, I think this
really helped. Third. Both

386
00:26:31.067 --> 00:26:36.067
the agency and the industry were
both glad to show progress

387
00:26:36.067 --> 00:26:42.000
at these sites rather than
facility investigation, and not

388
00:26:42.000 --> 00:26:47.000
having a clear marker to show
progress until

389
00:26:47.000 --> 00:26:52.000
the remedy selection I am
overstating a little,

390
00:26:52.000 --> 00:26:57.000
but being able to show that
progress was really important.

391
00:26:57.000 --> 00:27:01.000
I can't necessarily prove it at
this point. I do think

392
00:27:01.000 --> 00:27:05.000
the focus of the environmental
indicators help us shorten the
time frames

393
00:27:05.000 --> 00:27:11.000
on the projects we worked on.
With that.

394
00:27:11.000 --> 00:27:16.000
The end of my slides, I will
pause for questions.

395
00:27:16.000 --> 00:27:22.000
>> We received a few questions
coming in. I will start with
this one James,

396
00:27:22.000 --> 00:27:26.000
feel free if we can expand this
one. One

397
00:27:26.000 --> 00:27:34.067
of the attendees is looking for
a specific example of EI?

398
00:27:34.067 --> 00:27:41.000
>> Yes this is Emmy, we will
talk

399
00:27:41.000 --> 00:27:46.000
specifically about environmental
indicator statuses what

400
00:27:46.000 --> 00:27:51.000
those are in the upcoming
slides, and a great amount of
detail, that

401
00:27:51.000 --> 00:27:52.000
will get answered soon.

402
00:27:52.000 --> 00:27:55.000
>> Okay.

403
00:27:55.000 --> 00:28:00.000
>> Likewise there is follow-up
questions about the phrase under

404
00:28:00.000 --> 00:28:05.000
control, should we hold off
until we go through the content?

405
00:28:05.000 --> 00:28:10.000
>> I think so, we will make it
very clear, would you think Jim?

406
00:28:10.000 --> 00:28:13.000
>> I agree covered in the
upcoming slides. We knew those

407
00:28:13.000 --> 00:28:15.000
two questions would come.

408
00:28:15.000 --> 00:28:18.000
>> Excellent.

409
00:28:18.000 --> 00:28:22.000
>> Next question someone would
like to know has

410
00:28:22.000 --> 00:28:26.000
the set of indicators been
customized for state use in
Ohio? They are

411
00:28:26.000 --> 00:28:32.067
asking is the training localized
in some way?

412
00:28:32.067 --> 00:28:35.067
>> No, all of these
environmental indicators

413
00:28:35.067 --> 00:28:40.000
I was speaking to on RCRA, what
we are doing is the same thing

414
00:28:40.000 --> 00:28:46.000
Region 5 is doing in Chicago.
Region 5 had responsibility for

415
00:28:46.000 --> 00:28:51.000
actions sites and we are
following the same guidance

416
00:28:51.000 --> 00:28:55.000
in the same training, the only
thing that was different maybe
would be

417
00:28:55.000 --> 00:29:01.000
the fact that we did RCRA refers
to the lien event on the

418
00:29:01.000 --> 00:29:05.000
transaction process in Ohio to
figure out how to streamline

419
00:29:05.000 --> 00:29:08.000
what we are doing and guidance
documents.

420
00:29:08.000 --> 00:29:13.000
All of the regulatory documents
are the same between

421
00:29:13.000 --> 00:29:15.000
us and the feds.

422
00:29:15.000 --> 00:29:17.000
>> Great

423
00:29:17.000 --> 00:29:19.000
>> I don't see any other
questions.

424
00:29:19.000 --> 00:29:24.000
We can carry on at this point in
time with the next

425
00:29:24.000 --> 00:29:27.000
segment in the training.

426
00:29:27.000 --> 00:29:30.000
>> All right good afternoon
everyone,

427
00:29:30.000 --> 00:29:33.234
my name is Boone O'Neil, as we

428
00:29:33.234 --> 00:29:38.000
said earlier I'm the
environmental indicator

429
00:29:38.000 --> 00:29:41.000
coordinator for the office of
Superfund remediation technology
and innovation,

430
00:29:41.000 --> 00:29:47.000
might be the longest acronym at
EPA, Jim gave a good

431
00:29:47.000 --> 00:29:51.000
overview of what the EI czar,
and now we will dive into the
specific

432
00:29:51.000 --> 00:29:57.000
of how we use the human exposure
indicators specifically.

433
00:29:57.000 --> 00:30:03.000
When we talk about designating a
site with a certain

434
00:30:03.000 --> 00:30:07.000
human exposure status, we use
the term human

435
00:30:07.000 --> 00:30:13.000
exposure determination what we
are striving for is the status
under

436
00:30:13.000 --> 00:30:19.000
control, and we will discuss
what has to happen for this to
occur,

437
00:30:19.000 --> 00:30:24.000
basically there must be no
unacceptable complete exposure
pathways.

438
00:30:24.000 --> 00:30:30.000
Between human health receptors
and toxic

439
00:30:30.000 --> 00:30:32.067
absences.

440
00:30:32.067 --> 00:30:37.067
We can make this positive
determination by gathering
information about those

441
00:30:37.067 --> 00:30:41.000
unacceptable pathways, then by
taking steps to

442
00:30:41.000 --> 00:30:47.000
mitigate those pathways or
confirming that none exist in
the first place.

443
00:30:47.000 --> 00:30:53.000
It's important to consider new
information that arises
continuously

444
00:30:53.000 --> 00:30:58.000
throughout the cleanup process
this status can change. Often it

445
00:30:58.000 --> 00:31:04.000
does overtime. It's also
important to note

446
00:31:04.000 --> 00:31:08.000
with reasonable certainty, and
documented at some point in the

447
00:31:08.000 --> 00:31:14.000
cleanup process. I will move
this green arrow out

448
00:31:14.000 --> 00:31:16.000
of the way here.

449
00:31:16.000 --> 00:31:21.000
Here is a good overview of what
the status type is for human
exposure.

450
00:31:21.000 --> 00:31:26.000
These are not necessarily
chronological order. For
example.

451
00:31:26.000 --> 00:31:32.067
If the site has human exposure
insufficient data,

452
00:31:32.067 --> 00:31:36.067
it doesn't have to change to the
next status type of

453
00:31:36.067 --> 00:31:40.000
not control active, it can
actually go straight to

454
00:31:40.000 --> 00:31:45.000
human exposure under control if
the data suggest that there are

455
00:31:45.000 --> 00:31:50.000
no pathways.

456
00:31:50.000 --> 00:31:53.000
We wanted to give you an
overview of the status type than
what they

457
00:31:53.000 --> 00:31:56.000
are, we will talk about them
individually.

458
00:31:56.000 --> 00:32:02.000
We will start with the most
basic human exposure status,

459
00:32:02.000 --> 00:32:08.000
this is HEID,

460
00:32:08.000 --> 00:32:17.000
he human exposure data, whether
they

461
00:32:17.000 --> 00:32:21.000
have the potential to be exposed
and we have several things to
evaluate

462
00:32:21.000 --> 00:32:25.000
we need to collect information
to characterize all the
potential

463
00:32:25.000 --> 00:32:29.000
exposure pathways. Typically it
happens during the initial
phases

464
00:32:29.000 --> 00:32:36.067
of the cleanup or the RFS phase
remedial

465
00:32:36.067 --> 00:32:40.000
feasibility study, after this we
have identified any

466
00:32:40.000 --> 00:32:46.000
exposure pathways, then we can
designate that site

467
00:32:46.000 --> 00:32:52.000
under control. If we do find
exposure pathways then we Ned

468
00:32:52.000 --> 00:32:56.000
-- Now complete with these
exposures if it rises above

469
00:32:56.000 --> 00:33:02.000
the threshold. This happens
after a risk assessment is
completed.

470
00:33:02.000 --> 00:33:07.000
This happens for every site
wherever there is a new pathway

471
00:33:07.000 --> 00:33:10.000
identified. Furthermore.

472
00:33:10.000 --> 00:33:15.000
The exposure pathways. If they
are not complete need to be

473
00:33:15.000 --> 00:33:20.000
anticipated rather than
theoretical, it has to be based
on current use

474
00:33:20.000 --> 00:33:26.000
of the site and not future use.

475
00:33:26.000 --> 00:33:30.000
This gets us into a gray area
where the RPMs, the remedial
program managers

476
00:33:30.000 --> 00:33:34.000
need to use their best judgment
in making determination so we
can

477
00:33:34.000 --> 00:33:39.934
convey the most acuity, the act

478
00:33:39.934 --> 00:33:46.934
of accurate information as a
site

479
00:33:46.934 --> 00:33:48.934
is deemed under control and
resurfaces as

480
00:33:48.934 --> 00:33:52.934
a pathway reemerging, we need to
change the status back

481
00:33:52.934 --> 00:33:58.934
to insufficient data, until we
can investigate those new
pathways.

482
00:33:58.934 --> 00:34:04.934
When we use this specific
designation

483
00:34:04.934 --> 00:34:09.934
trend 20. we need to set a date
to

484
00:34:09.934 --> 00:34:16.934
make a determination detail what
we will do to gather that
information.

485
00:34:16.934 --> 00:34:22.934
That was a lot of details about
insufficient data, we want to
open

486
00:34:22.934 --> 00:34:26.934
it up to a polling question to
see how well

487
00:34:26.934 --> 00:34:29.934
you are understanding the so
far.

488
00:34:29.934 --> 00:34:33.000
Let's try to answer that first
question.

489
00:34:33.000 --> 00:34:37.067
I will turn it over to Jean, to

490
00:34:37.067 --> 00:34:40.000
moderate responses.

491
00:34:40.000 --> 00:34:46.000
>> Again in the lower left
corner you will see

492
00:34:46.000 --> 00:34:52.000
Poll question, respond what is
your human exposure

493
00:34:52.000 --> 00:34:58.000
that status determination? You
can

494
00:34:58.000 --> 00:35:00.000
click the circle to the left of
the answer you think correct

495
00:35:00.000 --> 00:35:11.000
in the situation. I would
encourage you to read through
the statement.

496
00:35:11.000 --> 00:35:16.000
-- You will want to answer what
is

497
00:35:16.000 --> 00:35:22.000
your human exposure status
determination? On a mobile

498
00:35:22.000 --> 00:35:25.000
device, you can see you can type
an answer into the

499
00:35:25.000 --> 00:35:31.067
Q&A window, there is no submit
question just click the submit

500
00:35:31.067 --> 00:35:34.067
to the left.

501
00:35:34.067 --> 00:35:37.067
I will turn on broadcast mode.

502
00:35:37.067 --> 00:35:43.000
Looks like half of the audience
thinks the answer is,

503
00:35:43.000 --> 00:35:49.000
C, the third is, B,

504
00:35:49.000 --> 00:35:56.000
and then the remainder is split.
The answer is?

505
00:35:56.000 --> 00:35:58.000
>> Will you turn it over to me?

506
00:35:58.000 --> 00:36:02.000
>> Yes to talk about the correct
answer.

507
00:36:02.000 --> 00:36:08.000
>> Okay everyone the answer is
C,,

508
00:36:08.000 --> 00:36:13.000
current human exposure under
control. It

509
00:36:13.000 --> 00:36:17.000
says we gathered data, that data
is sufficient to allow

510
00:36:17.000 --> 00:36:20.000
us to make a determination.

511
00:36:20.000 --> 00:36:25.000
It doesn't show there is any
potential pathway, based on

512
00:36:25.000 --> 00:36:31.067
that data we can categorize this
site under

513
00:36:31.067 --> 00:36:39.000
human exposure HEUC, before we
go to the

514
00:36:39.000 --> 00:36:43.000
second question, does anyone
have any questions about that? I
want

515
00:36:43.000 --> 00:36:49.000
to make sure everyone
understands why it is

516
00:36:49.000 --> 00:36:53.000
HEUC, rather than the other
options?

517
00:36:53.000 --> 00:36:54.000
>> This is Amy.

518
00:36:54.000 --> 00:36:56.000
>> Go ahead.

519
00:36:56.000 --> 00:37:02.000
>> Someone is asking about how
long to collect data for a

520
00:37:02.000 --> 00:37:05.000
determination? For HEID?

521
00:37:05.000 --> 00:37:11.000
>> It depends on the site and
the remedial program manager,

522
00:37:11.000 --> 00:37:16.000
whenever you feel every existing
pathway has been thoroughly

523
00:37:16.000 --> 00:37:21.000
investigated and known, and you
have data to

524
00:37:21.000 --> 00:37:27.000
determine whether or not those
pathways are completed.

525
00:37:27.000 --> 00:37:33.067
That is about the time when you
gather enough

526
00:37:33.067 --> 00:37:39.000
data based on what the data
suggest, in this case, it didn't

527
00:37:39.000 --> 00:37:45.000
expose any potential pathways.

528
00:37:45.000 --> 00:37:48.000
I hope that answers the
question.

529
00:37:48.000 --> 00:37:51.000
>> Is there anything else before
we move on

530
00:37:51.000 --> 00:37:54.000
to the next question?

531
00:37:54.000 --> 00:37:57.000
>> A few people thought they had
to answer the bottom question

532
00:37:57.000 --> 00:38:01.000
they didn't realize they were
answering this one, they

533
00:38:01.000 --> 00:38:06.000
are starting here and then we
will move down. Someone did has

534
00:38:06.000 --> 00:38:11.000
a class-size statement, if the
CSM shows vapor as a pathway,
there's

535
00:38:11.000 --> 00:38:15.000
no data, should we conclude it
is all under control?

536
00:38:15.000 --> 00:38:18.000
>> Right.

537
00:38:18.000 --> 00:38:23.000
>> You need to have data that
thoroughly

538
00:38:23.000 --> 00:38:28.000
describes the threat of the
pathway not simply that it
exists. If you

539
00:38:28.000 --> 00:38:33.067
need more information about the
vapor intrusion to determine
whether

540
00:38:33.067 --> 00:38:39.000
or not that particular intrusion
rises above

541
00:38:39.000 --> 00:38:45.000
not acceptable threshold or
whether or not

542
00:38:45.000 --> 00:38:51.000
it is completed to human
receptors, you need to

543
00:38:51.000 --> 00:38:56.000
gather that information until
you

544
00:38:56.000 --> 00:39:01.000
have enough data to answer those
bigger questions of whether or
not

545
00:39:01.000 --> 00:39:03.000
it's completed.

546
00:39:03.000 --> 00:39:07.000
We will continue to discuss this
and vapor intrusion is a pretty

547
00:39:07.000 --> 00:39:09.000
tricky pathway. In particular.

548
00:39:09.000 --> 00:39:14.000
We will continue to discuss this
in the following slides.

549
00:39:14.000 --> 00:39:17.000
>> This is Amy I want to chime
in.

550
00:39:17.000 --> 00:39:23.000
-- This is Emmy, I want to chime

551
00:39:23.000 --> 00:39:28.000
in, it's great for people to ask
you what about that? That is the

552
00:39:28.000 --> 00:39:32.067
intent, we realize there is a
very simplified

553
00:39:32.067 --> 00:39:36.067
representation with these mini
quizzes if you want to call them

554
00:39:36.067 --> 00:39:42.000
that, it's great that people are
connecting the dots, to

555
00:39:42.000 --> 00:39:47.000
say maybe I needed more data,
what is

556
00:39:47.000 --> 00:39:53.000
it, and what is the CSM say?
Great questions to think about.

557
00:39:53.000 --> 00:39:56.000
>> Great point Emmy.

558
00:39:56.000 --> 00:40:02.000
Jean, can we clear the Polls,

559
00:40:02.000 --> 00:40:08.000
and answer the second part? We
may have had spoilers

560
00:40:08.000 --> 00:40:11.000
in the discussion.

561
00:40:11.000 --> 00:40:14.000
>> Again we can look at the
second question on the slide,

562
00:40:14.000 --> 00:40:19.000
with that additional data that
suggest this may

563
00:40:19.000 --> 00:40:28.000
be occurring, what is your up
dated status?

564
00:40:28.000 --> 00:40:34.067
A, B, C, D or E?

565
00:40:34.067 --> 00:40:39.000
Let's take a look at how the
audience has voted 85% are

566
00:40:39.000 --> 00:40:42.000
picking option B.

567
00:40:42.000 --> 00:40:48.000
with a handful of both with
option

568
00:40:48.000 --> 00:40:50.000
A.

569
00:40:50.000 --> 00:40:53.000
what would the answer be?

570
00:40:53.000 --> 00:40:58.000
>> Everyone got this correct for
the most part. If there is a
vapor

571
00:40:58.000 --> 00:41:04.000
intrusion on site and you don't
know quite know

572
00:41:04.000 --> 00:41:10.000
if it is completed and rises
above, then you need

573
00:41:10.000 --> 00:41:15.000
to keep that site, in the
description nothing suggests

574
00:41:15.000 --> 00:41:20.000
that it is occurring that is
completed or unacceptable it
just

575
00:41:20.000 --> 00:41:26.000
simply says maybe occurring that
maybe language,

576
00:41:26.000 --> 00:41:31.067
may be indicative for further
data before you can

577
00:41:31.067 --> 00:41:35.067
make this determination. Any
questions about that?

578
00:41:35.067 --> 00:41:41.000
>> Okay. We just had a comment

579
00:41:41.000 --> 00:41:46.000
about emerging contaminants,
there are some concerns

580
00:41:46.000 --> 00:41:51.000
and questions when we have an
emerging contaminant, when would
that status

581
00:41:51.000 --> 00:41:57.000
change to HEID?

582
00:41:57.000 --> 00:42:01.000
>> Hot topic these days. Emmy
will cover that

583
00:42:01.000 --> 00:42:06.000
later on in the presentation if
we can hold off on that
discussion?

584
00:42:06.000 --> 00:42:09.000
>> I think in the interest of
time let's carry on.

585
00:42:09.000 --> 00:42:21.000
>> All right. Thank you everyone
for indulging in this pup quiz.

586
00:42:21.000 --> 00:42:26.000
My screen is not working with
me.

587
00:42:26.000 --> 00:42:31.067
Now we will move to discuss the
next status of human exposure
not

588
00:42:31.067 --> 00:42:36.067
under control. Hopefully our
discussion on the

589
00:42:36.067 --> 00:42:40.000
HEID that constitute its
determination of not control,
just to be clear,

590
00:42:40.000 --> 00:42:46.000
there needs to be an except
double and completed pathway or

591
00:42:46.000 --> 00:42:54.000
when pathways are reasonably
deemed completed or
unacceptable.

592
00:42:54.000 --> 00:42:59.000
This status just like all status
for human exposure, this is a

593
00:42:59.000 --> 00:43:06.000
sitewide designation. Even if
one is the outstanding problem,
even

594
00:43:06.000 --> 00:43:11.000
the whole site has to fit the
status that

595
00:43:11.000 --> 00:43:17.000
applies to that one is the
problem just as we

596
00:43:17.000 --> 00:43:23.000
need to have a date for when we
have sufficient data for

597
00:43:23.000 --> 00:43:29.000
HEID we need to set a date

598
00:43:29.000 --> 00:43:35.000
for when we expected to come
under control or

599
00:43:35.000 --> 00:43:40.934
not controlled, to mitigate all
impact on

600
00:43:40.934 --> 00:43:43.934
human health.

601
00:43:43.934 --> 00:43:49.934
We will continue with our pup
quiz. One

602
00:43:49.934 --> 00:43:51.934
question this time.

603
00:43:51.934 --> 00:43:59.934
We specifically want to look at
interesting example,

604
00:43:59.934 --> 00:44:02.934
James will you open that pulling
back up again, identify the
correct

605
00:44:02.934 --> 00:44:18.934
human exposure status for this
situation.

606
00:45:03.000 --> 00:45:09.000
Right answer a tricky question,

607
00:45:09.000 --> 00:45:15.000
the right answer is is in

608
00:45:15.000 --> 00:45:21.000
this case, though the top six,

609
00:45:21.000 --> 00:45:27.000
we have mitigated the pathway to
human exposure,

610
00:45:27.000 --> 00:45:32.067
by providing bottled water, and
we have controlled the situation

611
00:45:32.067 --> 00:45:35.067
in that sense.

612
00:45:35.067 --> 00:45:43.000
The correct answer is HEUC

613
00:45:43.000 --> 00:45:47.000
human exposure under control, we
have a few clarifying

614
00:45:47.000 --> 00:45:50.000
comments come in.

615
00:45:50.000 --> 00:45:54.000
>> From aerosol showering or if
it's being used for bathing?

616
00:45:54.000 --> 00:46:01.000
Another assumption about thermal
exposures?

617
00:46:01.000 --> 00:46:06.000
>> All of those kind of those
examples or situations

618
00:46:06.000 --> 00:46:10.000
that are outside the scope of
this question could lead to a
different

619
00:46:10.000 --> 00:46:16.000
designation, based on this
information strictly, doesn't
indicate

620
00:46:16.000 --> 00:46:21.000
there being any potential
completed pathways, the

621
00:46:21.000 --> 00:46:25.000
only pathway there was, the
groundwater that was being

622
00:46:25.000 --> 00:46:30.000
consumed. In this case no longer
consume because we mitigated
that

623
00:46:30.000 --> 00:46:35.067
pathway by providing the bottled
water, and just based on

624
00:46:35.067 --> 00:46:41.000
the slide and what it is here,
again it could be other
situations

625
00:46:41.000 --> 00:46:47.000
occurring that would lead us to
rethink the status.

626
00:46:47.000 --> 00:46:51.000
>> Emmy just chiming in, great

627
00:46:51.000 --> 00:46:57.000
people are thinking oh well,
ingestion if that is the only
pathway,

628
00:46:57.000 --> 00:47:01.000
and is there another way for
people to be exposed? Great
question

629
00:47:01.000 --> 00:47:05.000
for the simplicity of this
question we are assuming only
the ingestion

630
00:47:05.000 --> 00:47:10.000
as drinking water of this
groundwater, this would

631
00:47:10.000 --> 00:47:13.000
be an issue. And why we would go
with human exposures. Under
control

632
00:47:13.000 --> 00:47:17.000
for mitigating the pathway.
Really great questions, a can

633
00:47:17.000 --> 00:47:23.000
change what your determination
will be.

634
00:47:23.000 --> 00:47:29.000
>> Right thank you how about we
move on. In the

635
00:47:29.000 --> 00:47:32.067
sake of time, and circle back.

636
00:47:32.067 --> 00:47:36.067
To the status of human exposure
under control

637
00:47:36.067 --> 00:47:39.000
which we alluded to a lot.

638
00:47:39.000 --> 00:47:42.000
By now it should be apparent
this status

639
00:47:42.000 --> 00:47:48.000
is designated to site where
there is no unacceptable

640
00:47:48.000 --> 00:47:51.000
pathways.

641
00:47:51.000 --> 00:47:57.000
Again the status is a sitewide
measure, if there is one

642
00:47:57.000 --> 00:48:01.000
OU under control we can't
designated

643
00:48:01.000 --> 00:48:05.000
under control, this status once
the data indicates there

644
00:48:05.000 --> 00:48:09.000
are no pathways, or taken steps
to mitigate those pathways like

645
00:48:09.000 --> 00:48:10.000
in the last example.

646
00:48:10.000 --> 00:48:16.000
It's also important to note.
This status occurs before the
site

647
00:48:16.000 --> 00:48:21.000
becomes construction complete,
this leads us to the next

648
00:48:21.000 --> 00:48:27.000
status type, which is current
human exposure under control and
all

649
00:48:27.000 --> 00:48:33.067
in place, which is the acronym

650
00:48:33.067 --> 00:48:37.067
HEPR, this also indicates all
construction is complete.

651
00:48:37.067 --> 00:48:43.000
Remedies are in place
functioning correctly.

652
00:48:43.000 --> 00:48:52.000
Sites that remain in the status.
After construction

653
00:48:52.000 --> 00:48:58.000
completed typically have ongoing
remediation actions or ongoing

654
00:48:58.000 --> 00:49:01.000
maintenance as needed.

655
00:49:01.000 --> 00:49:06.000
The final status. For human
exposure

656
00:49:06.000 --> 00:49:11.000
is cumin human exposure under
control and long-term human

657
00:49:11.000 --> 00:49:15.000
health protection achieved, from
this mouthful, we

658
00:49:15.000 --> 00:49:21.000
have given the acronym of age
HPA. --

659
00:49:21.000 --> 00:49:33.067
Acronym HHPA cleanup

660
00:49:33.067 --> 00:49:41.000
goals include long-term soil,
groundwater or restoration
needs,

661
00:49:41.000 --> 00:49:46.000
this status applies not to NPL
sites but deleted site as well
as those

662
00:49:46.000 --> 00:49:51.000
who have reached the completion
status,

663
00:49:51.000 --> 00:49:55.000
the ultimate status that we are
trying to get to that

664
00:49:55.000 --> 00:49:58.000
indicate that we have rotted
under control, done all of the
construction

665
00:49:58.000 --> 00:50:03.000
and completed all cleanup needs,
these are the end result of the

666
00:50:03.000 --> 00:50:08.000
human exposure designation. I
know we have

667
00:50:08.000 --> 00:50:13.000
covered a lot of information so
far. For the human exposure
status,

668
00:50:13.000 --> 00:50:17.000
and I do want to open it up to
any questions about any of the
different

669
00:50:17.000 --> 00:50:21.000
status types.

670
00:50:21.000 --> 00:50:25.000
>> We had a few questions coming
in about the unacceptable

671
00:50:25.000 --> 00:50:30.000
threshold quote, is that 10 to
the -6 or some range?

672
00:50:30.000 --> 00:50:35.067
>> There are specific guidance
depending

673
00:50:35.067 --> 00:50:41.000
on the contaminant of concern
that has to do with

674
00:50:41.000 --> 00:50:47.000
not really a blanket statement I
can

675
00:50:47.000 --> 00:50:51.000
give, but one of those things
really dependent

676
00:50:51.000 --> 00:50:57.000
on the kind of substance of
concern and what the exposure

677
00:50:57.000 --> 00:51:02.000
pathways are and what can be
done to mitigate them. That is
an

678
00:51:02.000 --> 00:51:07.000
open ended language that we left
up to the RPM to have
flexibility

679
00:51:07.000 --> 00:51:11.000
in determining that status based
on the site conditions.

680
00:51:11.000 --> 00:51:16.000
There is a specific guidance for
what is considered unacceptable

681
00:51:16.000 --> 00:51:25.000
depending on the toxic concern.

682
00:51:25.000 --> 00:51:27.000
>> Go ahead Emmy.

683
00:51:27.000 --> 00:51:33.067
>> I was just going to add. You
will hear we have the

684
00:51:33.067 --> 00:51:37.067
term unacceptable, there is no
unacceptable human pathways,

685
00:51:37.067 --> 00:51:43.000
no acceptable levels, and it
does get to what is acceptable?

686
00:51:43.000 --> 00:51:47.000
Were not saying it will be
pristine, but under the
Superfund

687
00:51:47.000 --> 00:51:53.000
cleanup of the risk range,
anything outside that risk

688
00:51:53.000 --> 00:51:56.000
range will be unacceptable if
that helps answer

689
00:51:56.000 --> 00:51:59.000
the question.

690
00:51:59.000 --> 00:52:03.000
>> Again I mentioned briefly
there is a risk assessment

691
00:52:03.000 --> 00:52:08.000
for each site and pathway
completed that takes into
account each detail,

692
00:52:08.000 --> 00:52:13.000
and what that threshold of exec
debility --

693
00:52:13.000 --> 00:52:16.000
Acceptability is.

694
00:52:16.000 --> 00:52:21.000
>> Two more questions, I think
we have time for. Someone

695
00:52:21.000 --> 00:52:25.000
asked for reference guidance
through this presentation, and
can you clarify

696
00:52:25.000 --> 00:52:29.000
what guidance are you
referencing?

697
00:52:29.000 --> 00:52:35.067
>> Was that for the guidance I
was

698
00:52:35.067 --> 00:52:38.000
just talking about?

699
00:52:38.000 --> 00:52:43.000
For the specific substances in
the threshold for

700
00:52:43.000 --> 00:52:47.000
the acceptability?

701
00:52:47.000 --> 00:52:51.000
I've given my contact
information if you would like to
reach out about

702
00:52:51.000 --> 00:52:55.000
specifics I would love to help
you out pointing you in the
right direction

703
00:52:55.000 --> 00:52:58.000
after the presentation.

704
00:52:58.000 --> 00:53:03.000
>> A number of people are
interested on documents with
specific

705
00:53:03.000 --> 00:53:09.000
thresholds -- We will remind
everyone how

706
00:53:09.000 --> 00:53:11.000
to reach out to Boone after.

707
00:53:11.000 --> 00:53:17.000
>> If someone wanted to know
does this mean HEPR long-term

708
00:53:17.000 --> 00:53:23.000
monitoring for

709
00:53:23.000 --> 00:53:26.000
[Indiscernible]?

710
00:53:26.000 --> 00:53:29.000
>> Can you clarify the question?

711
00:53:29.000 --> 00:53:35.000
>> All I have, what means

712
00:53:35.000 --> 00:53:40.934
HEPR, for sites, if the Smith,

713
00:53:40.934 --> 00:53:44.934
the submitter wants to clarify.

714
00:53:44.934 --> 00:53:50.934
>> It would depend on a couple
of things.

715
00:53:50.934 --> 00:53:56.934
MA will discuss emergent
contemnor and

716
00:53:56.934 --> 00:54:02.934
-- Him he will discuss emergent
contaminants.

717
00:54:02.934 --> 00:54:06.934
And whether they have provided a
complete exposure

718
00:54:06.934 --> 00:54:12.934
pathway, this is deemed
unexpected will

719
00:54:12.934 --> 00:54:18.934
have data suggesting that, the
site will not be

720
00:54:18.934 --> 00:54:24.934
HEPR. In that scenario go back

721
00:54:24.934 --> 00:54:30.934
to, the determination of human
exposure and sufficient

722
00:54:30.934 --> 00:54:37.067
data. If you have the data to

723
00:54:37.067 --> 00:54:43.000
back up that claim, I wouldn't
suggest it is a blanket

724
00:54:43.000 --> 00:54:47.000
way to handle contaminants. If
you leave

725
00:54:47.000 --> 00:54:53.000
the site as HEPR, it suggested
is

726
00:54:53.000 --> 00:54:56.000
controlled. If you don't have
the data to suggest

727
00:54:56.000 --> 00:55:02.000
it's controlled, then it cannot
be HEPR, hope

728
00:55:02.000 --> 00:55:05.000
that helps.

729
00:55:05.000 --> 00:55:09.000
>> Absolutely. I don't see any
new questions why don't we move

730
00:55:09.000 --> 00:55:12.000
on. We are at one hour left in
today's training.

731
00:55:12.000 --> 00:55:19.000
>> Emmy will take it from here.

732
00:55:19.000 --> 00:55:24.000
>> We will go over a worksheet
when used in making

733
00:55:24.000 --> 00:55:29.000
human exposure at Sipe, I
realized it's not readable in
your

734
00:55:29.000 --> 00:55:34.067
manual there is a blown up
version of this chart and we
will break

735
00:55:34.067 --> 00:55:38.000
it on down to the next couple of
slides,

736
00:55:38.000 --> 00:55:44.000
it says questions, this will
help answer the question of what

737
00:55:44.000 --> 00:55:50.000
my EID should be. Starting

738
00:55:50.000 --> 00:55:53.000
out with question one.

739
00:55:53.000 --> 00:55:56.000
Do I have enough data, if the
answer

740
00:55:56.000 --> 00:56:02.000
is no, then you know you have
insufficient data to determine

741
00:56:02.000 --> 00:56:08.000
HEID, if you do, come down to
question number

742
00:56:08.000 --> 00:56:11.000
2. All other exposure cleanup
goals have been

743
00:56:11.000 --> 00:56:17.000
met for the entire site? You
have met all of those goals and
cleanup

744
00:56:17.000 --> 00:56:20.000
levels in the decision for
example, if this answer is

745
00:56:20.000 --> 00:56:26.000
yes, then your current human
exposures are under control and
long-term

746
00:56:26.000 --> 00:56:31.067
exposure has been achieved. This
is where we all want to be
eventually

747
00:56:31.067 --> 00:56:33.067
right?

748
00:56:33.067 --> 00:56:37.067
If the answer is no, come down
to question number three, asking
are

749
00:56:37.067 --> 00:56:40.000
there complete pathways between
contaminated groundwater,

750
00:56:40.000 --> 00:56:43.000
surface water, and human
receptors?

751
00:56:43.000 --> 00:56:48.000
Such that human exposures can
reasonably be

752
00:56:48.000 --> 00:56:54.000
expected? If the answer is yes,
then go to step four Mac,

753
00:56:54.000 --> 00:57:00.000
-- Go to step 4. if no, go to

754
00:57:00.000 --> 00:57:06.000
step 5. -- Now going on to step
4.

755
00:57:06.000 --> 00:57:10.000
is there reasonably anticipated
exposures identified

756
00:57:10.000 --> 00:57:14.000
with those in three?

757
00:57:14.000 --> 00:57:19.000
>> Again acceptable that word.
Say they answer

758
00:57:19.000 --> 00:57:25.000
is, no, your human exposures are
not under control.

759
00:57:25.000 --> 00:57:31.067
If the answer is, yes, then is
it within acceptable limits?

760
00:57:31.067 --> 00:57:34.067
No, it is not.

761
00:57:34.067 --> 00:57:39.000
If it is, under current
conditions go to step number
five

762
00:57:39.000 --> 00:57:51.000
Mac. Is a complete?

763
00:57:51.000 --> 00:57:56.000
Is it helpful to be in place and
not effective?

764
00:57:56.000 --> 00:58:01.000
Keep that in mind you will meet
one of these criteria is, one

765
00:58:01.000 --> 00:58:05.000
not all but some, the current
human exposure is under control,

766
00:58:05.000 --> 00:58:10.000
and if you can meet all
criteria, then you can say yes,
current

767
00:58:10.000 --> 00:58:14.000
exposures are under control and
protective remedies are in
place.

768
00:58:14.000 --> 00:58:20.000
That is the status that you
would have while there is
long-term groundwater

769
00:58:20.000 --> 00:58:24.000
happening and you want to meet
those cleanup levels,

770
00:58:24.000 --> 00:58:28.000
protective remedies are in place
and that's when would use the
status.

771
00:58:28.000 --> 00:58:34.067
That is the flow logic to help
you understand what

772
00:58:34.067 --> 00:58:39.000
EI you have for this logic on
your sites.

773
00:58:39.000 --> 00:58:43.000
I will pause for a second to see
if

774
00:58:43.000 --> 00:58:48.000
there are any questions coming
in, or next activity, we will do
an

775
00:58:48.000 --> 00:58:54.000
emergent contaminant website
exercise.

776
00:58:54.000 --> 00:58:58.000
I'm hoping this group exercise
will help everyone better
understand.

777
00:58:58.000 --> 00:59:00.000
Did we have any questions before
we jump

778
00:59:00.000 --> 00:59:03.000
into this?

779
00:59:03.000 --> 00:59:07.000
>> I'm seeing the

780
00:59:07.000 --> 00:59:10.000
question not under control, and
they wonder if there is a date
when

781
00:59:10.000 --> 00:59:15.000
the site should be brought under
control what other factors to
consider

782
00:59:15.000 --> 00:59:21.000
when they can list under
control?

783
00:59:21.000 --> 00:59:26.000
>> I imagine for most sites,
there is a broader site

784
00:59:26.000 --> 00:59:31.067
management plans or golf for
cleanup

785
00:59:31.067 --> 00:59:37.067
at that site, for facilities
maybe laid out with this

786
00:59:37.067 --> 00:59:43.000
agreement, depending on how
SSA's are written.

787
00:59:43.000 --> 00:59:44.734
Ideally, those you have

788
00:59:44.734 --> 00:59:48.000
identified it in your
justification language

789
00:59:48.000 --> 00:59:52.000
would reflect overall plan for
the site, it might be saying

790
00:59:52.000 --> 00:59:58.000
now we are in 2020. and you are
not in control for your

791
00:59:58.000 --> 01:00:04.000
site pending the glower, for
this site under control we

792
01:00:04.000 --> 01:00:08.000
will achieve in 2030 or whatever

793
01:00:08.000 --> 01:00:12.000
appropriate date, look at the
broader context available for
your site

794
01:00:12.000 --> 01:00:20.000
to select that date. Hopefully
that answers the question.

795
01:00:20.000 --> 01:00:26.000
>> Emmy I see a number of
responses now which of the

796
01:00:26.000 --> 01:00:32.067
following emergency, you that
you have dealt

797
01:00:32.067 --> 01:00:38.000
with wide variety of answers. As
I am scrolling through,

798
01:00:38.000 --> 01:00:44.000
it looks like about a third of
the audience has letter

799
01:00:44.000 --> 01:00:47.000
C.

800
01:00:47.000 --> 01:00:53.000
it looks like 25% have been
situation

801
01:00:53.000 --> 01:00:59.000
A.

802
01:00:59.000 --> 01:01:05.000
And 20% is in situation

803
01:01:05.000 --> 01:01:11.000
B, you are not sure or D.

804
01:01:11.000 --> 01:01:14.000
None of the above.

805
01:01:14.000 --> 01:01:18.000
Big distribution there, we are
across all options.

806
01:01:18.000 --> 01:01:21.000
>> Which is good hopefully this
exercise will help everyone
better

807
01:01:21.000 --> 01:01:26.000
understand where they can look
at determinations for the site
if

808
01:01:26.000 --> 01:01:32.067
you are none of the above group,
that's great, but I wouldn't

809
01:01:32.067 --> 01:01:38.000
get too comfortable, it may be
the emergent contaminant you
deal

810
01:01:38.000 --> 01:01:41.000
with hasn't come to light yet.

811
01:01:41.000 --> 01:01:45.000
Still a good practice to come
through this

812
01:01:45.000 --> 01:01:49.000
exercise together, asking the
same question under

813
01:01:49.000 --> 01:01:54.000
these three scenarios I will
provide more detail here. Again,
really

814
01:01:54.000 --> 01:02:02.000
trying to help you understand
which and under control the
status to

815
01:02:02.000 --> 01:02:06.000
something else. When you are
dealing with them the emerging

816
01:02:06.000 --> 01:02:11.000
contaminant imagine if you will,
this has

817
01:02:11.000 --> 01:02:17.000
addressing soil and groundwater
contamination, some of these

818
01:02:17.000 --> 01:02:23.000
include TCE, and soil removal.
For that

819
01:02:23.000 --> 01:02:30.000
part that was over risk based
model, your last determination

820
01:02:30.000 --> 01:02:34.067
done last year, human exposures
under control. It was recently
determination

821
01:02:34.067 --> 01:02:40.000
there was historical use at the
site. Monitoring

822
01:02:40.000 --> 01:02:46.000
wells were monitored and the
data was not back yet,

823
01:02:46.000 --> 01:02:51.000
and not determined to drink the
water

824
01:02:51.000 --> 01:02:56.000
sources. This is the same
scenario presented in

825
01:02:56.000 --> 01:03:01.000
a different form, you will see
site A, in the blue

826
01:03:01.000 --> 01:03:06.000
box, the black dots are the
monitoring wells existing
contaminant

827
01:03:06.000 --> 01:03:12.000
plumes, no off-site, there are
some public drinking water

828
01:03:12.000 --> 01:03:16.000
supply wells, and further down
gradient, residential homes, and
one of them

829
01:03:16.000 --> 01:03:22.000
has private drinking water well,
this is what you have so

830
01:03:22.000 --> 01:03:26.000
far, collected sampling that is
not back yet, you're not

831
01:03:26.000 --> 01:03:31.000
sure what had gone on given that
situation what human exposure

832
01:03:31.000 --> 01:03:36.000
determination which applies in
that scenario? Is it under
control?

833
01:03:36.000 --> 01:03:41.934
Insufficient data? Or human
exposure not under control?

834
01:03:41.934 --> 01:03:47.934
I hope we can pull up a

835
01:03:47.934 --> 01:03:54.934
Poll, to test the votes. We see
them coming in.

836
01:03:54.934 --> 01:03:59.934
>> For those of you typing into
a Q&A window, absolutely go
ahead.

837
01:03:59.934 --> 01:04:04.934
Emmy as a note as well, number
of people typed

838
01:04:04.934 --> 01:04:09.934
in they have been and although
situations on the earlier Poll.

839
01:04:09.934 --> 01:04:12.934
>> All right.

840
01:04:12.934 --> 01:04:18.934
>> I can see ND

841
01:04:18.934 --> 01:04:24.934
for these three quarters have
select did the

842
01:04:24.934 --> 01:04:34.000
option where you said
insufficient

843
01:04:34.000 --> 01:04:40.000
data, and some of you this had

844
01:04:40.000 --> 01:04:44.000
the most votes for insufficient
data, this

845
01:04:44.000 --> 01:04:49.000
can be some status for
monitoring and you are waiting
on

846
01:04:49.000 --> 01:04:54.000
more, and you know you need
more, and you could select
insufficient

847
01:04:54.000 --> 01:05:04.000
data, but you could also choose
to keep status

848
01:05:04.000 --> 01:05:09.000
A, under control, until the data
is connected, and you

849
01:05:09.000 --> 01:05:12.000
have sufficient data to trigger
that change in

850
01:05:12.000 --> 01:05:17.000
your environmental indicator
before you go in and pull the
trigger to

851
01:05:17.000 --> 01:05:22.000
say, we have insufficient data,
I would actually state either
one

852
01:05:22.000 --> 01:05:28.000
of those, could potentially be
argued as a justifiable

853
01:05:28.000 --> 01:05:34.067
human exposure for the site. One
other sidenote.

854
01:05:34.067 --> 01:05:40.000
Especially right now. We are
tracking human exposure across

855
01:05:40.000 --> 01:05:44.000
our sites, if you were to change
from under control to not

856
01:05:44.000 --> 01:05:48.000
under control, EPA headquarters
will likely have a lot of
follow-up

857
01:05:48.000 --> 01:05:53.000
questions, and wants to know
exactly what to be good,

858
01:05:53.000 --> 01:05:58.000
to get it back to that control
status keep in mind. Just
something

859
01:05:58.000 --> 01:06:03.000
to keep in mind to be aware of.
One year has passed.

860
01:06:03.000 --> 01:06:09.000
You have more data for your
site. Your back to

861
01:06:09.000 --> 01:06:12.000
making annual EI determination
we do them every

862
01:06:12.000 --> 01:06:18.000
year, this data shows there are
emerging contaminants in

863
01:06:18.000 --> 01:06:22.000
some of your wells, and these
are the monitoring wells,

864
01:06:22.000 --> 01:06:26.000
but you still don't have data
for the public drinking water
supply

865
01:06:26.000 --> 01:06:31.067
wells and the private drinking
water well, you have a plan to
collect

866
01:06:31.067 --> 01:06:37.067
the data over the next year,
showing in the graphic

867
01:06:37.067 --> 01:06:43.000
here, monitoring wells don't
have emergency

868
01:06:43.000 --> 01:06:49.000
contaminant, that

869
01:06:49.000 --> 01:06:53.000
emergent contaminant, that shows
that is present, we don't

870
01:06:53.000 --> 01:06:58.000
know what is going on with the
supply wells and don't know what
is going

871
01:06:58.000 --> 01:07:03.000
on over here on this private
drinking water well, given

872
01:07:03.000 --> 01:07:09.000
this information. I will ask
again, what human exposure EI

873
01:07:09.000 --> 01:07:15.000
determination would you select?

874
01:07:15.000 --> 01:07:21.000
I will pull up the Poll and you
will be able to

875
01:07:21.000 --> 01:07:30.000
cast your vote.

876
01:07:30.000 --> 01:07:32.067
>> Emmy very quickly while we
are letting the

877
01:07:32.067 --> 01:07:36.067
info on this cushion, earlier
comment came in

878
01:07:36.067 --> 01:07:42.000
or a clarifying question,
wouldn't it be less conservative
to public

879
01:07:42.000 --> 01:07:54.000
select each HEUC?

880
01:07:54.000 --> 01:07:59.000
>> You could say they are not
under control at this site
emergent contaminant

881
01:07:59.000 --> 01:08:04.000
we don't know to what extent it
has migrated

882
01:08:04.000 --> 01:08:08.000
and we will be conservative to
say not in control, that is an
option

883
01:08:08.000 --> 01:08:13.000
that can be selected. You
definitely are going to want to
plan on how

884
01:08:13.000 --> 01:08:17.000
to get it under control by first
getting all is sufficient

885
01:08:17.000 --> 01:08:18.000
data necessary.

886
01:08:18.000 --> 01:08:22.000
And they follow-up actions
needed to address it. So it is
no

887
01:08:22.000 --> 01:08:23.000
longer an issue.

888
01:08:23.000 --> 01:08:26.000
>> Okay.

889
01:08:26.000 --> 01:08:30.000
>> That balance between do I
pull the trigger and

890
01:08:30.000 --> 01:08:35.067
change it from not under control
status? To either insufficient
data?

891
01:08:35.067 --> 01:08:43.000
Or do I pull it from that

892
01:08:43.000 --> 01:08:49.000
not under control, or wait until
I have solid information?

893
01:08:49.000 --> 01:08:56.000
Subjective independent on the
site and the circumstances.

894
01:08:56.000 --> 01:09:01.000
>> Looking back at the question
for slide 39. what human
exposure

895
01:09:01.000 --> 01:09:05.000
EI determination applies in this
example?

896
01:09:05.000 --> 01:09:14.000
We see two thirds picking option
B,

897
01:09:14.000 --> 01:09:20.000
and even split between A, and C.

898
01:09:20.000 --> 01:09:23.000
What is the answer?

899
01:09:23.000 --> 01:09:27.000
>> Is sufficient data would be
the most appropriate

900
01:09:27.000 --> 01:09:31.067
determination to make, and you
have some from the monitoring
wells

901
01:09:31.067 --> 01:09:34.067
and you still need to know what
is happening in those drinking
water

902
01:09:34.067 --> 01:09:38.000
wells, to me insufficient data
would be making sense here.

903
01:09:38.000 --> 01:09:44.000
>> As we just went over, if you
wanted

904
01:09:44.000 --> 01:09:49.000
to go, not under control, you
could potentially justify that

905
01:09:49.000 --> 01:09:55.000
as well. I wish it was black and
white and

906
01:09:55.000 --> 01:10:00.000
it was easy to say absolutely
this or absolutely that status,
absolutely

907
01:10:00.000 --> 01:10:03.000
there is a lot of gray space,
which is what we are trying to
show

908
01:10:03.000 --> 01:10:08.000
with these examples. Let's
continue on to the next part of
the exercise.

909
01:10:08.000 --> 01:10:14.000
Maybe it'll be less gray,
another year passed.

910
01:10:14.000 --> 01:10:20.000
Now you have data showing
emerging contaminants for

911
01:10:20.000 --> 01:10:25.000
those supply wells, and to date,
you haven't eliminated

912
01:10:25.000 --> 01:10:30.000
to access that private well so
you don't know there. Here in
the

913
01:10:30.000 --> 01:10:35.067
graphic, monitoring wells, the
red they have these

914
01:10:35.067 --> 01:10:40.000
emerging contaminant, these
orange, I will move the

915
01:10:40.000 --> 01:10:44.000
arrow here and here, also have
above the screening level risk,

916
01:10:44.000 --> 01:10:47.000
and we still don't know what is
happening on site, because we
have

917
01:10:47.000 --> 01:10:52.000
property owner that doesn't want
us to sample their well, that
happened

918
01:10:52.000 --> 01:10:56.000
quite a bit actually. Given all

919
01:10:56.000 --> 01:10:59.000
this information. Same question.

920
01:10:59.000 --> 01:11:05.000
What EI would you select here?

921
01:11:05.000 --> 01:11:11.000
Hopefully you are getting ready
to answer.

922
01:11:11.000 --> 01:11:14.000
Answering what you would
determine for your site

923
01:11:14.000 --> 01:11:18.000
over the course of three years
right as the scenario is laid
out. I can

924
01:11:18.000 --> 01:11:23.000
see quite a number of responses
coming in for human exposure not

925
01:11:23.000 --> 01:11:29.000
under control. Given they have
emerging

926
01:11:29.000 --> 01:11:31.067
contaminants in those drinking
water wells, that is a complete

927
01:11:31.067 --> 01:11:37.067
pathway. People can reasonably
be expected to

928
01:11:37.067 --> 01:11:43.000
be exposed that pathway, and
reasonable

929
01:11:43.000 --> 01:11:49.000
to say this is not under control
for the site.

930
01:11:49.000 --> 01:11:54.000
>> Can you confirm Emmy, has
that been tested in the diagram?

931
01:11:54.000 --> 01:11:57.000
>> Yes.

932
01:11:57.000 --> 01:12:00.000
>> So in this example.

933
01:12:00.000 --> 01:12:06.000
We have the data back from the
public on drinking water

934
01:12:06.000 --> 01:12:09.000
wells, and we know what is going
on with the sample wells,

935
01:12:09.000 --> 01:12:13.000
and we just didn't know what was
going on at the residential one.

936
01:12:13.000 --> 01:12:21.000
The private drinking water well.

937
01:12:21.000 --> 01:12:27.000
>> Like you were saying the
distribution there, the option
there was C.

938
01:12:27.000 --> 01:12:32.067
>> All right I hope that helps
illustrate

939
01:12:32.067 --> 01:12:35.067
when you pull the trigger so to
speak, I

940
01:12:35.067 --> 01:12:41.000
don't know if that is the best
springing, but when you make
that jump, to

941
01:12:41.000 --> 01:12:46.000
go to insufficient data, or you
know that in complete pathway

942
01:12:46.000 --> 01:12:50.000
that you fully change to human
exposures not under control.

943
01:12:50.000 --> 01:12:55.000
2 life examples, when they
change

944
01:12:55.000 --> 01:13:01.000
to in the insufficient data,
here is

945
01:13:01.000 --> 01:13:06.000
an example at the Air Force
Base,

946
01:13:06.000 --> 01:13:09.000
May 2019. there was a
determination made insufficient
determination

947
01:13:09.000 --> 01:13:15.000
to determine human exposures,
because we were those that
detected

948
01:13:15.000 --> 01:13:19.000
on base, and the water well was
sampled,

949
01:13:19.000 --> 01:13:25.000
they did not contain PFAS,

950
01:13:25.000 --> 01:13:34.000
but they did have unacceptable
levels and infiltration was

951
01:13:34.000 --> 01:13:38.934
installed, we want more
information and limited

952
01:13:38.934 --> 01:13:42.934
sampling done in 2017. And a
broader plan

953
01:13:42.934 --> 01:13:48.934
in 2019. I don't believe the
data is back from that yet and
we

954
01:13:48.934 --> 01:13:54.934
identified insufficient data,
and where they did have a
specific exposure

955
01:13:54.934 --> 01:13:59.934
at that one well they took
action to mitigate it. Here is
another

956
01:13:59.934 --> 01:14:04.934
example. At the Aberdeen proving
grounds,

957
01:14:04.934 --> 01:14:10.934
May 2019 insufficient data,
because the facility is
undergoing

958
01:14:10.934 --> 01:14:14.934
PAS I, to determine if PFAS is
present

959
01:14:14.934 --> 01:14:20.934
in the drinking water sources.
There will be sufficient
information

960
01:14:20.934 --> 01:14:23.934
at the site.

961
01:14:23.934 --> 01:14:28.934
Those are the 2 row case
examples hopefully that

962
01:14:28.934 --> 01:14:33.000
helps take what we did in the
group exercise, and

963
01:14:33.000 --> 01:14:36.000
plug it into the real life
situation.

964
01:14:36.000 --> 01:14:42.000
We will go ahead and continue
on,

965
01:14:42.000 --> 01:14:45.000
are there any questions James?

966
01:14:45.000 --> 01:14:48.000
>> Emmy a lot of questions were
coming

967
01:14:48.000 --> 01:14:52.000
in on that scenario, I will read
one, are there specific triggers

968
01:14:52.000 --> 01:14:57.000
that would prompt changing
status of light of these annual

969
01:14:57.000 --> 01:15:00.000
reviews? Do you wait to update
annually even though

970
01:15:00.000 --> 01:15:04.000
you know something as change
before then?

971
01:15:04.000 --> 01:15:07.000
>> Boone, do you want to answer
that?

972
01:15:07.000 --> 01:15:10.000
>> Sure.

973
01:15:10.000 --> 01:15:15.000
>> We would actually prefer that
the

974
01:15:15.000 --> 01:15:20.000
status would be updated as soon
as you feel you have enough

975
01:15:20.000 --> 01:15:23.000
information to determine a new
determination.

976
01:15:23.000 --> 01:15:29.000
It's best to have some kind of
document at some point in the

977
01:15:29.000 --> 01:15:37.067
cleanup part of the process, as
a David

978
01:15:37.067 --> 01:15:42.000
-- To answer your question no,
you don't have to wait for the

979
01:15:42.000 --> 01:15:48.000
annual review. It can be done at
any point that you feel you have

980
01:15:48.000 --> 01:15:52.000
sufficient data to make that
determination.

981
01:15:52.000 --> 01:15:57.000
>> Great in the interest of time
we will

982
01:15:57.000 --> 01:16:00.000
carry on with the next segment.

983
01:16:00.000 --> 01:16:07.000
>> All right thank you Emmy for
clearing up some of that stuff
about

984
01:16:07.000 --> 01:16:11.000
emerging contaminants, we will
move on to groundwater
migration.

985
01:16:11.000 --> 01:16:18.000
This EI gets less attention, and
still very important.

986
01:16:18.000 --> 01:16:23.000
Indicator is used to convey
information about

987
01:16:23.000 --> 01:16:27.000
the level of groundwater
limitation in the migration of
that whether

988
01:16:27.000 --> 01:16:33.067
it is stabilized including
unacceptable discharge into

989
01:16:33.067 --> 01:16:36.067
surface water.

990
01:16:36.067 --> 01:16:39.000
Just like the human exposure
indicator, this determination
must be made

991
01:16:39.000 --> 01:16:44.000
with reasonable certainty, and
you must have sufficient data to
make

992
01:16:44.000 --> 01:16:50.000
a determine that documentation.

993
01:16:50.000 --> 01:16:54.000
You can do this with five-year
reviews.

994
01:16:54.000 --> 01:16:58.000
It is handled in a similar way
as human exposure

995
01:16:58.000 --> 01:17:04.000
even if it is measuring
something else. Before we dive
into

996
01:17:04.000 --> 01:17:10.000
the details, I will do another
polling question. There is one
scenario

997
01:17:10.000 --> 01:17:14.000
here. We will see if we can
answer this question.

998
01:17:14.000 --> 01:17:20.000
I will open up those poll
responses, you will have three

999
01:17:20.000 --> 01:17:23.000
options here.

1000
01:17:23.000 --> 01:17:28.000
>> Now with that question on the
bottom, and easier Breese fonts

1001
01:17:28.000 --> 01:17:33.067
choice, remember you are only
answering

1002
01:17:33.067 --> 01:17:38.000
one question at the bottom of
the slide, I'm

1003
01:17:38.000 --> 01:17:54.000
looking at a number of answers
coming in,

1004
01:17:54.000 --> 01:18:00.000
we have some questions here and
I will wait

1005
01:18:00.000 --> 01:18:14.000
to come back to these later?

1006
01:18:14.000 --> 01:18:17.000
>> Let's base this off of what
it says here and we

1007
01:18:17.000 --> 01:18:26.000
can handle those specific
situations later

1008
01:18:26.000 --> 01:18:35.067
about a third they say it
depends, how would you

1009
01:18:35.067 --> 01:18:38.000
answer this one Boone?

1010
01:18:38.000 --> 01:18:44.000
>> You can argue options a or C
here.

1011
01:18:44.000 --> 01:18:49.000
If the migration is stabilized
you can say the groundwater

1012
01:18:49.000 --> 01:18:55.000
migration is under control, but
the stabilization

1013
01:18:55.000 --> 01:19:00.000
is not explicitly addressed in
the situation, so you need that

1014
01:19:00.000 --> 01:19:03.000
information. If it's not
addressed.

1015
01:19:03.000 --> 01:19:09.000
Obviously, if it is not under
control obviously

1016
01:19:09.000 --> 01:19:15.000
you would go with a different
answer here. Essentially

1017
01:19:15.000 --> 01:19:23.000
it looks like they are putting
in some kind of

1018
01:19:23.000 --> 01:19:28.000
remedy. To treat the
groundwater. Again it's not

1019
01:19:28.000 --> 01:19:32.067
just the groundwater is
contaminated, you have to make
sure there is no

1020
01:19:32.067 --> 01:19:39.000
migration. It's not just
groundwater but migration under
control as well.

1021
01:19:39.000 --> 01:19:44.000
>> Hey Boone. Sure --

1022
01:19:44.000 --> 01:19:50.000
>> If you have a pump entry

1023
01:19:50.000 --> 01:19:52.000
happening, is that still
migration?

1024
01:19:52.000 --> 01:19:55.000
>> Great question.

1025
01:19:55.000 --> 01:20:01.000
>> You would need in evaluating,
there

1026
01:20:01.000 --> 01:20:06.000
are certain boundaries you would
want to keep that plume from

1027
01:20:06.000 --> 01:20:12.000
migrating. As long as it's not
migrating outside of

1028
01:20:12.000 --> 01:20:18.000
the boundary, you can say it's
under control. If that plume is
outside

1029
01:20:18.000 --> 01:20:23.000
of that boundary that you have
determined,

1030
01:20:23.000 --> 01:20:28.000
even though it may be shrinking,
you can classified

1031
01:20:28.000 --> 01:20:33.067
as not under control until it's
back within that boundary that

1032
01:20:33.067 --> 01:20:39.000
you have determined.

1033
01:20:39.000 --> 01:20:44.000
Are there any other questions
about this?

1034
01:20:44.000 --> 01:20:49.000
>> Somebody wanted to know what
is stabilization in this case?
What

1035
01:20:49.000 --> 01:20:58.000
is that phrase and what that
men's -- What that means?

1036
01:20:58.000 --> 01:21:02.000
>> Whether that is in
predetermined boundary that

1037
01:21:02.000 --> 01:21:07.000
you are monitoring, when we say
stabilized, we mean it's not
migrating

1038
01:21:07.000 --> 01:21:09.000
outside of that boundary.

1039
01:21:09.000 --> 01:21:12.000
>> All right excellent.

1040
01:21:12.000 --> 01:21:15.000
>> I don't see any other
questions coming in.

1041
01:21:15.000 --> 01:21:18.000
>> Perhaps we can move on.

1042
01:21:18.000 --> 01:21:24.000
>> We will cover the different
status types. There are

1043
01:21:24.000 --> 01:21:29.000
less types then the human
indicator, for types here

1044
01:21:29.000 --> 01:21:33.067
for groundwater migration, the
first one, when there is no

1045
01:21:33.067 --> 01:21:39.000
contaminated groundwater on-site
or the site conditions

1046
01:21:39.000 --> 01:21:51.000
don't warrant those for
limiting, that is just

1047
01:21:51.000 --> 01:21:57.000
GMNA, then GMID,

1048
01:21:57.000 --> 01:22:02.000
and also under control and not
under control

1049
01:22:02.000 --> 01:22:07.000
for the status types and
evaluating. You will need

1050
01:22:07.000 --> 01:22:12.000
to evaluate these three, see if
there is sufficient data in the

1051
01:22:12.000 --> 01:22:15.000
first place. Then you have to
determine whether or not

1052
01:22:15.000 --> 01:22:20.000
those plumes are expanding
outside of those boundaries,
whether they

1053
01:22:20.000 --> 01:22:23.000
are stabilized.

1054
01:22:23.000 --> 01:22:26.000
Then evaluate if there is any
discharge into

1055
01:22:26.000 --> 01:22:31.067
surface water. Those are the
three things to keep in mind in
evaluating

1056
01:22:31.067 --> 01:22:38.000
the water in making that
determination.

1057
01:22:38.000 --> 01:22:43.000
>> So just some further details
about

1058
01:22:43.000 --> 01:22:49.000
this again, this is the status,
you will need to take

1059
01:22:49.000 --> 01:22:56.000
into account all that you have
potential groundwater migrating.

1060
01:22:56.000 --> 01:23:01.000
One thing to keep in mind, we do
have a term monitored

1061
01:23:01.000 --> 01:23:05.000
natural attenuation come in some
senses, this may be an
acceptable

1062
01:23:05.000 --> 01:23:10.000
remedy, this is where we just
allow the groundwater to

1063
01:23:10.000 --> 01:23:14.000
cleanse itself over time. As
long as it

1064
01:23:14.000 --> 01:23:17.000
is contained within those
boundaries.

1065
01:23:17.000 --> 01:23:23.000
Again it is very important
always to monitor whether or not
the surface

1066
01:23:23.000 --> 01:23:27.000
water, to keep in mind as well.

1067
01:23:27.000 --> 01:23:33.000
>> So in a similar way. Looking

1068
01:23:33.000 --> 01:23:37.000
through the human exposure
checklist, and we

1069
01:23:37.000 --> 01:23:42.934
will do that just to show how
they use this

1070
01:23:42.934 --> 01:23:45.934
as a tool in making these
evaluations.

1071
01:23:45.934 --> 01:23:50.934
>> You will need to start by
asking the questions, do they
have contaminated

1072
01:23:50.934 --> 01:23:55.934
groundwater? And if

1073
01:23:55.934 --> 01:23:56.934
they have had this in the past.

1074
01:23:56.934 --> 01:24:01.934
>> If the answer is no, go ahead
with the first status covered if

1075
01:24:01.934 --> 01:24:07.934
not, then it is not a site where

1076
01:24:07.934 --> 01:24:11.934
it needs to be monitored, if the
answer is yes, go through the
checklist

1077
01:24:11.934 --> 01:24:14.934
starting with 1.

1078
01:24:14.934 --> 01:24:21.934
We will determine if there is
sufficient data to make a
determination,

1079
01:24:21.934 --> 01:24:34.000
the answer is no, obviously then
you go to the site designation
of

1080
01:24:34.000 --> 01:24:40.000
GMID. If the answer is

1081
01:24:40.000 --> 01:24:46.000
no on risk based measures, then
acceptable,

1082
01:24:46.000 --> 01:24:51.000
then you have it under control
if the answer

1083
01:24:51.000 --> 01:24:57.000
is yes, proceed to strut to Step
3. and if it is

1084
01:24:57.000 --> 01:25:01.000
that plume mobilized if it's not
then the

1085
01:25:01.000 --> 01:25:07.000
groundwater migration is not
under control. If it is, then
you continue

1086
01:25:07.000 --> 01:25:13.000
with the steps and arrive at
step four.

1087
01:25:13.000 --> 01:25:19.000
Here you decide if there is
discharge

1088
01:25:19.000 --> 01:25:25.000
at the surface one, if there is
not you can continue

1089
01:25:25.000 --> 01:25:34.067
skip go to step six. Then you
ask

1090
01:25:34.067 --> 01:25:38.000
if it's shown to be currently
acceptable. This is the only
other

1091
01:25:38.000 --> 01:25:42.000
aspect, not just the moderation
of the plume, you

1092
01:25:42.000 --> 01:25:48.000
will reevaluate based on that as
well. If the answer is no, then

1093
01:25:48.000 --> 01:25:54.000
you give a site status of not
control.

1094
01:25:54.000 --> 01:25:58.000
If it is yes, go to step six,
hopefully groundwater will

1095
01:25:58.000 --> 01:26:04.000
be grounded to verify that it
has

1096
01:26:04.000 --> 01:26:06.000
remained within the existing
area of contaminated

1097
01:26:06.000 --> 01:26:12.000
groundwater. Hopefully yes, you
are doing that monitoring.

1098
01:26:12.000 --> 01:26:17.000
If the answer is yes, then
designate the site the indicator

1099
01:26:17.000 --> 01:26:22.000
as groundwater migration under
control,

1100
01:26:22.000 --> 01:26:26.000
hopefully that is a helpful
step-by-step process in shorting
out all of these

1101
01:26:26.000 --> 01:26:31.067
various processes and conditions
to help you arrive at the
correct

1102
01:26:31.067 --> 01:26:34.067
determination. I will open it
up.

1103
01:26:34.067 --> 01:26:39.000
>> Boone we are waiting for
questions to

1104
01:26:39.000 --> 01:26:45.000
see if they come in, for
misunderstand, we see

1105
01:26:45.000 --> 01:26:51.000
at this very large site, say
they have access to the site and

1106
01:26:51.000 --> 01:26:52.000
it's controlled.

1107
01:26:52.000 --> 01:26:57.000
There is institutional control,
to ensure

1108
01:26:57.000 --> 01:27:01.000
groundwater is not being used
for drinking water purpose and
wells

1109
01:27:01.000 --> 01:27:05.000
are not implemented, we hear a
lot in the argument, no one can

1110
01:27:05.000 --> 01:27:09.000
use the water. So groundwater
migration is under

1111
01:27:09.000 --> 01:27:14.000
control, it's challenging to
clarify if your plumes are
moving

1112
01:27:14.000 --> 01:27:18.000
across the site regardless of
whether offense, your

1113
01:27:18.000 --> 01:27:24.000
migration is still happening.
It's still not under control,

1114
01:27:24.000 --> 01:27:29.000
in that instance.

1115
01:27:29.000 --> 01:27:33.067
>> Excellent point, that shows
how the two indicators will

1116
01:27:33.067 --> 01:27:38.000
be tied in together. If there is
a consumption of that
groundwater,

1117
01:27:38.000 --> 01:27:44.000
then obviously it can lead to
evaluate and

1118
01:27:44.000 --> 01:27:50.000
that human exposure
determination as Amy said, if
human exposure

1119
01:27:50.000 --> 01:27:57.000
is not even an element of
investigating groundwater, if

1120
01:27:57.000 --> 01:28:02.000
it is been migrated outside of
that boundary, resurfacing
groundwater,

1121
01:28:02.000 --> 01:28:06.000
regardless, you would need to
state it's not under control.

1122
01:28:06.000 --> 01:28:09.000
>> Okay.

1123
01:28:09.000 --> 01:28:11.000
>> We did have question come in.

1124
01:28:11.000 --> 01:28:16.000
>> Sorry a comment came in about
difficulty distinguishing
between

1125
01:28:16.000 --> 01:28:32.067
G MNA -- Being not applicable
and

1126
01:28:32.067 --> 01:28:46.000
-- The slide MNA,

1127
01:28:46.000 --> 01:28:51.000
not a status for this indicator
but a remedy

1128
01:28:51.000 --> 01:28:55.000
to contaminated groundwater
which we

1129
01:28:55.000 --> 01:29:04.000
highlight. That

1130
01:29:04.000 --> 01:29:07.000
remedy since there is not
anything that we are actually
doing except

1131
01:29:07.000 --> 01:29:11.000
for making sure that the
groundwater doesn't migrate,

1132
01:29:11.000 --> 01:29:17.000
and we are letting it naturally
over time reduce

1133
01:29:17.000 --> 01:29:23.000
in contamination. Good point.

1134
01:29:23.000 --> 01:29:28.000
They are similar sounding
acronyms I will

1135
01:29:28.000 --> 01:29:32.067
go back to the slide, this is
the status given to the site
where there

1136
01:29:32.067 --> 01:29:38.000
is not any contaminated
groundwater for concern

1137
01:29:38.000 --> 01:29:44.000
every status has groundwater
migration even

1138
01:29:44.000 --> 01:29:51.000
if there is none occurring at
the site

1139
01:29:51.000 --> 01:29:56.000
hopefully that clears it up.

1140
01:29:56.000 --> 01:30:00.000
If there are no other questions
on groundwater is there anything

1141
01:30:00.000 --> 01:30:03.000
else you want to mention?

1142
01:30:03.000 --> 01:30:08.000
>> Not that I see right now. In
the interest of time we should
begin

1143
01:30:08.000 --> 01:30:11.000
again and pause later for
questions.

1144
01:30:11.000 --> 01:30:20.000
>> The last topic we want to
cover

1145
01:30:20.000 --> 01:30:24.000
covers both these EI's, the best
management practices, for EI's.

1146
01:30:24.000 --> 01:30:28.000
For the internal document we
have, for

1147
01:30:28.000 --> 01:30:33.067
general management practices
that we are expected to follow,

1148
01:30:33.067 --> 01:30:39.000
they each have their own way of
approaching needs.

1149
01:30:39.000 --> 01:30:45.000
Management focuses on EI's,
really important. It's not just

1150
01:30:45.000 --> 01:30:50.000
a measure, quarterly, we need
management whether that

1151
01:30:50.000 --> 01:30:55.000
is that headquarters or the
regions to

1152
01:30:55.000 --> 01:30:58.000
pay attention to these as well.

1153
01:30:58.000 --> 01:31:03.000
There should be a bit of a
priority for EPA, directly
related

1154
01:31:03.000 --> 01:31:08.000
to public safety. That is a high
concern and a high priority.

1155
01:31:08.000 --> 01:31:13.000
You heard mentioned earlier for
these paragraphs for the

1156
01:31:13.000 --> 01:31:24.000
site that the human exposure
status of the ID and not
controlled.

1157
01:31:24.000 --> 01:31:30.000
And each of these sites that
have the to designated exposures

1158
01:31:30.000 --> 01:31:35.067
HENC or HEID, has information

1159
01:31:35.067 --> 01:31:40.000
about that to the public, these
are all available on the
website.

1160
01:31:40.000 --> 01:31:46.000
Also on the human exposure
dashboard that you saw earlier.

1161
01:31:46.000 --> 01:31:52.000
It is important to keep those
updated.

1162
01:31:52.000 --> 01:31:57.000
It's a good source of
information if you live in a
community

1163
01:31:57.000 --> 01:32:02.000
where there is a Superfund site
nearby, and what

1164
01:32:02.000 --> 01:32:07.000
kind of risk you can assume is
happening.

1165
01:32:07.000 --> 01:32:13.000
Information sharing also very
helpful from coordination

1166
01:32:13.000 --> 01:32:19.000
standpoint. We like to keep EI's
consistent across the region

1167
01:32:19.000 --> 01:32:25.000
and headquarters, so that we can
have a standard for evaluating

1168
01:32:25.000 --> 01:32:29.000
EI's, and we have shared
information as best as possible.
It is also

1169
01:32:29.000 --> 01:32:32.067
important to have an
understanding of different
measures and how they

1170
01:32:32.067 --> 01:32:41.000
impact each other. How they are
tied together.

1171
01:32:41.000 --> 01:32:46.000
The protective determinations,
and of course with

1172
01:32:46.000 --> 01:32:52.000
anything that you monitor, and
you evaluate, you need quality
data,

1173
01:32:52.000 --> 01:32:56.000
and you need to up date the data
SEMs

1174
01:32:56.000 --> 01:33:04.000
are constantly staying on top of
that. Any questions about EMPs?

1175
01:33:04.000 --> 01:33:10.000
>> I see no questions. We can go
on, we can come back to them

1176
01:33:10.000 --> 01:33:14.000
if someone types a lengthy one
and I see it

1177
01:33:14.000 --> 01:33:15.000
pop in later.

1178
01:33:15.000 --> 01:33:17.000
>> I will hand it back over to
Amy.

1179
01:33:17.000 --> 01:33:19.000
>> Great thank you.

1180
01:33:19.000 --> 01:33:24.000
>> We are coming to the last
section of the webinar looking
at other

1181
01:33:24.000 --> 01:33:30.000
cirque components and other
components of

1182
01:33:30.000 --> 01:33:36.000
CERCLA, and anticipated use for

1183
01:33:36.000 --> 01:33:41.934
SWRAU, the Superfund

1184
01:33:41.934 --> 01:33:45.934
anticipated use, and even EI,
how are these items

1185
01:33:45.934 --> 01:33:48.934
interrelated?

1186
01:33:48.934 --> 01:33:53.934
>> With five-year reviews, new
information should be considered

1187
01:33:53.934 --> 01:33:58.934
during that five year review
process, maybe like

1188
01:33:58.934 --> 01:34:03.934
exposure pathway or
contamination, emergent
contaminants, or

1189
01:34:03.934 --> 01:34:09.934
any other evidence or
uncertainty with migration,

1190
01:34:09.934 --> 01:34:15.934
you can imagine if you have a
new exposure pathway, that may

1191
01:34:15.934 --> 01:34:21.934
affect for exposures, again does
the

1192
01:34:21.934 --> 01:34:24.934
pathway exist?

1193
01:34:24.934 --> 01:34:28.934
Add this information, and in the
five-year review process,

1194
01:34:28.934 --> 01:34:34.000
this will also make sure you are
looking at it

1195
01:34:34.000 --> 01:34:39.000
during your EI determinations,
five-year review happens every
five years,

1196
01:34:39.000 --> 01:34:42.000
and these all are made annually.

1197
01:34:42.000 --> 01:34:48.000
>> The other item I mentioned

1198
01:34:48.000 --> 01:34:52.000
on was SWRAU, for SWRAU you need

1199
01:34:52.000 --> 01:34:58.000
to have a determination
protected remedies in place, and

1200
01:34:58.000 --> 01:35:04.000
achieved. Those are the statuses
that are allowed for SWRAU,

1201
01:35:04.000 --> 01:35:10.000
if you have insufficient data,
it is not under control call

1202
01:35:10.000 --> 01:35:16.000
without that next level.

1203
01:35:16.000 --> 01:35:21.000
They are not eligible for SWRAU.

1204
01:35:21.000 --> 01:35:27.000
I will clarify, there are
briefings that just issued in
the past few

1205
01:35:27.000 --> 01:35:32.067
weeks, that are talking about
some sites and whether them
changing

1206
01:35:32.067 --> 01:35:37.067
his status can change the
status, if you need

1207
01:35:37.067 --> 01:35:41.000
that link let us know we will
get you the latest on that. For
example

1208
01:35:41.000 --> 01:35:46.000
if you have a protective remedy
in place. Now you have emerging

1209
01:35:46.000 --> 01:35:50.000
contaminants situation and your
realizing, there is insufficient

1210
01:35:50.000 --> 01:35:56.000
data for us to know, we will
change EI and exposure status.
That might

1211
01:35:56.000 --> 01:36:04.000
mean you have to click off the
switch for your

1212
01:36:04.000 --> 01:36:08.000
SWRAU, there is a lot of
pressure as you do that,
potentially from

1213
01:36:08.000 --> 01:36:11.000
management or headquarters,
because we are tracking all
these things.

1214
01:36:11.000 --> 01:36:16.000
Ultimately you want to do what
is right for yourself

1215
01:36:16.000 --> 01:36:20.000
if those exposures are
happening, and you don't know if
there happening,

1216
01:36:20.000 --> 01:36:24.000
because you don't have enough
information and you need that
change, then it

1217
01:36:24.000 --> 01:36:29.000
all comes down to developing
appropriate language to say what
is happening

1218
01:36:29.000 --> 01:36:35.067
at the site and why the change
is needed.

1219
01:36:35.067 --> 01:36:39.000
I will get off my soapbox for a
second. And again if you have to

1220
01:36:39.000 --> 01:36:45.000
retract, as far as that
designation come to light, you

1221
01:36:45.000 --> 01:36:48.000
could have information that
affects all of this information.

1222
01:36:48.000 --> 01:36:53.000
Maybe not only just the
five-year review, and exposure
pathways,

1223
01:36:53.000 --> 01:36:59.000
and you have to change it from
under control to not under your
control,

1224
01:36:59.000 --> 01:37:04.000
and determination really
important

1225
01:37:04.000 --> 01:37:09.000
how you can change one item and
it affects others. We were
noting

1226
01:37:09.000 --> 01:37:15.000
at the headquarters level, that
five-year review information

1227
01:37:15.000 --> 01:37:23.000
we had designations for sites
that human it

1228
01:37:23.000 --> 01:37:28.000
has exposures that are not under
control, and making updates to
all

1229
01:37:28.000 --> 01:37:30.000
of these sites.

1230
01:37:30.000 --> 01:37:36.067
>> Last topic I want to talk up
out,

1231
01:37:36.067 --> 01:37:41.000
remember they are not intended
for baseline

1232
01:37:41.000 --> 01:37:46.000
risk assessment, when you are
doing your characterization

1233
01:37:46.000 --> 01:37:50.000
for the site, all of the work
associated with the sampling.

1234
01:37:50.000 --> 01:37:53.000
The information considered.

1235
01:37:53.000 --> 01:37:55.000
That is different. When you are
doing your

1236
01:37:55.000 --> 01:37:59.000
EI determination the information
is used as available you may not

1237
01:37:59.000 --> 01:38:04.000
necessarily have a work plan,
answering all the data

1238
01:38:04.000 --> 01:38:07.000
questions you have.

1239
01:38:07.000 --> 01:38:11.000
It might be possible to have EI
under control in particular for

1240
01:38:11.000 --> 01:38:17.000
human exposure even before
remedy is selected are fully
implemented.

1241
01:38:17.000 --> 01:38:21.000
As long as those pathways are
mitigated, then you

1242
01:38:21.000 --> 01:38:25.000
might not have all of those
records of decisions

1243
01:38:25.000 --> 01:38:40.000
in place, when you are making
determinations just another
thing to be

1244
01:38:40.000 --> 01:38:43.000
aware of.

1245
01:38:43.000 --> 01:38:55.000
The last slide, the one

1246
01:38:55.000 --> 01:39:01.000
I use most, this also helpful,
and

1247
01:39:01.000 --> 01:39:06.000
about the language I encourage
you to click

1248
01:39:06.000 --> 01:39:11.000
on this Superfund program
implementation manual providing
sample

1249
01:39:11.000 --> 01:39:17.000
language and justification
paragraphs that go into

1250
01:39:17.000 --> 01:39:29.000
the public facing dashboard
these are all

1251
01:39:29.000 --> 01:39:34.067
publicly available I highly
recommend you check them

1252
01:39:34.067 --> 01:39:49.000
out. These indicators,

1253
01:39:49.000 --> 01:39:55.000
we want to make sure that we
have good

1254
01:39:55.000 --> 01:40:04.000
data remember

1255
01:40:04.000 --> 01:40:10.000
you can work with your project
team and coordinator, lastly,

1256
01:40:10.000 --> 01:40:19.000
it could potentially have these
and be

1257
01:40:19.000 --> 01:40:25.000
aware of those relationships.

1258
01:40:25.000 --> 01:40:30.000
>> I do have questions in the
queue, I will start with the

1259
01:40:30.000 --> 01:40:36.067
most recent ones. A number of
people have asked where

1260
01:40:36.067 --> 01:40:42.000
they can find that guidance, is
there a website they can get

1261
01:40:42.000 --> 01:40:45.000
to the guidance?

1262
01:40:45.000 --> 01:40:54.000
>> Are we able to send a link
out to other participants?

1263
01:40:54.000 --> 01:40:59.000
>> I can also send it now. I
will

1264
01:40:59.000 --> 01:41:02.000
get it out in the following
email.

1265
01:41:02.000 --> 01:41:07.000
>> I will try to

1266
01:41:07.000 --> 01:41:10.000
get it out to everyone before we
and the webinar if not we will
send

1267
01:41:10.000 --> 01:41:13.000
it out.

1268
01:41:13.000 --> 01:41:25.000
>> What

1269
01:41:25.000 --> 01:41:31.067
participants, and wouldn't one
want to be more

1270
01:41:31.067 --> 01:41:37.067
considerate of, from this
viewpoint, why would

1271
01:41:37.067 --> 01:41:41.000
they notice if it is under
control,

1272
01:41:41.000 --> 01:41:45.000
I'm not sure can anyone talk
about that?

1273
01:41:45.000 --> 01:41:49.000
>> Remember having human health
under control,

1274
01:41:49.000 --> 01:41:55.000
this does not mean that you have
all

1275
01:41:55.000 --> 01:42:00.000
risk we want to make sure that
these

1276
01:42:00.000 --> 01:42:06.000
are all dealt with quickly as
possible. And implementing

1277
01:42:06.000 --> 01:42:10.000
cleanups, and the environment,
these are just one

1278
01:42:10.000 --> 01:42:16.000
way to measure progress towards
that goal human exposure

1279
01:42:16.000 --> 01:42:22.000
is not the same as having

1280
01:42:22.000 --> 01:42:28.000
implemented, and protective
remedies are in place,

1281
01:42:28.000 --> 01:42:33.067
this is just something to keep
in mind, these are not quite

1282
01:42:33.067 --> 01:42:38.000
apples to apples, EPA has
identified a site, under
control. The remedies

1283
01:42:38.000 --> 01:42:45.000
haven't been selected or
implemented yet

1284
01:42:45.000 --> 01:42:55.000
there is still money for
investigating the site towards
the cleanup decisions.

1285
01:42:55.000 --> 01:42:57.000
>> Thank you and me.

1286
01:42:57.000 --> 01:42:59.000
>> Another question come in.

1287
01:42:59.000 --> 01:43:05.000
>> There are concerns. And
particularly with the examples

1288
01:43:05.000 --> 01:43:11.000
and somewhat objective, how can
there be a comprehensive

1289
01:43:11.000 --> 01:43:17.000
assessment where statuses have
determined

1290
01:43:17.000 --> 01:43:22.000
availability? Can you reflect on
that?

1291
01:43:22.000 --> 01:43:28.000
>> I can totally acknowledge
there is a lot in these

1292
01:43:28.000 --> 01:43:31.000
determinations.

1293
01:43:31.000 --> 01:43:36.000
-- At headquarters we try

1294
01:43:36.000 --> 01:43:41.934
to work with rpm's to have
consistency throughout the
program. This is

1295
01:43:41.934 --> 01:43:46.934
really site specific
determinations that includes
what is

1296
01:43:46.934 --> 01:43:51.934
necessary. I agree there is a
lot of gray. It

1297
01:43:51.934 --> 01:43:57.934
is not always black and white,
and it is good to rely on those

1298
01:43:57.934 --> 01:44:00.934
resources.

1299
01:44:00.934 --> 01:44:06.934
EPA headquarters for example,
and

1300
01:44:06.934 --> 01:44:11.934
if you are not sure the right
fit for your site.

1301
01:44:11.934 --> 01:44:17.934
>> Both of us are great
resources if we want

1302
01:44:17.934 --> 01:44:20.934
to reach out.

1303
01:44:20.934 --> 01:44:28.934
I'm in the remediation program
and we both deal with EI,

1304
01:44:28.934 --> 01:44:32.000
for a lot of the same sites
often.

1305
01:44:32.000 --> 01:44:35.000
She makes a good point.

1306
01:44:35.000 --> 01:44:41.000
There is no one way,

1307
01:44:41.000 --> 01:44:43.000
to make human exposure
determination for

1308
01:44:43.000 --> 01:44:48.000
example, those guidelines we lay
out are the

1309
01:44:48.000 --> 01:44:52.000
best way to approach on how to
make these consistent and making
these

1310
01:44:52.000 --> 01:44:57.000
things specifically to be met,
the way that we

1311
01:44:57.000 --> 01:45:02.000
have details you rely on, and
those different thresholds for
different

1312
01:45:02.000 --> 01:45:07.000
site statuses, depend and we
want

1313
01:45:07.000 --> 01:45:13.000
them to have flexibility for
those decisions based on the
conditions

1314
01:45:13.000 --> 01:45:17.000
of the site.

1315
01:45:17.000 --> 01:45:23.000
>> Excellent can we go back to
look at the categories

1316
01:45:23.000 --> 01:45:28.000
for human health some
participants

1317
01:45:28.000 --> 01:45:32.067
weren't quite as familiar with
those options when we were
classifying

1318
01:45:32.067 --> 01:45:43.000
with the class would be.

1319
01:45:43.000 --> 01:45:48.000
-- That was for the human
exposure team or both?

1320
01:45:48.000 --> 01:45:53.000
>> If you can't, why not

1321
01:45:53.000 --> 01:45:56.000
do both?

1322
01:45:56.000 --> 01:46:01.000
>> On slide 22.

1323
01:46:01.000 --> 01:46:07.000
Like I said in my presentation,
the basic site status,

1324
01:46:07.000 --> 01:46:13.000
for data, in the earlier

1325
01:46:13.000 --> 01:46:20.000
site process, this could be a
designation which

1326
01:46:20.000 --> 01:46:26.000
reached elevated statuses and
pathway of concern that need to
be investigated.

1327
01:46:26.000 --> 01:46:31.067
You can always change these
statuses back,

1328
01:46:31.067 --> 01:46:39.000
if you know the site conditions
are

1329
01:46:39.000 --> 01:46:43.000
so dire, and you don't need to
investigate and you know
already, the site

1330
01:46:43.000 --> 01:46:47.000
is not controlled, if you are
not under control, that is where
you

1331
01:46:47.000 --> 01:46:52.000
have those completed pathways
for human exposure that is
unacceptable.

1332
01:46:52.000 --> 01:46:56.000
When you don't have that, you
have human

1333
01:46:56.000 --> 01:47:02.000
exposure under control, for
current conditions. This

1334
01:47:02.000 --> 01:47:07.000
is before you reach those
construction completion

1335
01:47:07.000 --> 01:47:12.000
milestones, where you have
protect

1336
01:47:12.000 --> 01:47:18.000
remedy in place, before all the
cleanup goals are achieved.

1337
01:47:18.000 --> 01:47:24.000
HEPR and HHPA

1338
01:47:24.000 --> 01:47:30.000
higher levels, and those
additional

1339
01:47:30.000 --> 01:47:34.067
thresholds that need to be met.
Every site has to

1340
01:47:34.067 --> 01:47:38.000
have one of these
categorizations. Any questions
about

1341
01:47:38.000 --> 01:47:41.000
that?

1342
01:47:41.000 --> 01:47:45.000
>> Okay I'm not seeing any
follow-up questions.

1343
01:47:45.000 --> 01:47:51.000
If we can quickly go through the
other category for groundwater,

1344
01:47:51.000 --> 01:47:55.000
I will get one more question in
before we close out.

1345
01:47:55.000 --> 01:48:04.000
>> Mudslide was out on?

1346
01:48:04.000 --> 01:48:13.000
Slide 48?

1347
01:48:13.000 --> 01:48:18.000
>> Quickly I will go through
these four status types.

1348
01:48:18.000 --> 01:48:24.000
For groundwater migration. For
GMNA,

1349
01:48:24.000 --> 01:48:29.000
not applicable in a data entry
field, these are

1350
01:48:29.000 --> 01:48:35.067
for sites that don't have
contaminated groundwater every
site has

1351
01:48:35.067 --> 01:48:40.000
to have a status if there are
none, then they get the status
of

1352
01:48:40.000 --> 01:48:46.000
GMNA, those that do have
groundwater or you

1353
01:48:46.000 --> 01:48:52.000
need other information to make
that determination then you give
it

1354
01:48:52.000 --> 01:48:57.000
GMID status, then specific
criteria

1355
01:48:57.000 --> 01:49:03.000
that we discussed for those two
types. That is a quick summary
of

1356
01:49:03.000 --> 01:49:06.000
all the different status types
for indicators I'd be happy

1357
01:49:06.000 --> 01:49:09.000
to answer any further questions.

1358
01:49:09.000 --> 01:49:14.000
If we run out of time today, my
contact information, and Emmys

1359
01:49:14.000 --> 01:49:20.000
contact information is in the
beginning of the presentation

1360
01:49:20.000 --> 01:49:23.000
if you'd like to reach out to
us.

1361
01:49:23.000 --> 01:49:25.000
>> Great I do want to circle
back to the subcategory

1362
01:49:25.000 --> 01:49:30.000
of questions for the specific
scenarios and when we will

1363
01:49:30.000 --> 01:49:35.067
change the status, when we hit
on it in an earlier question, we
want

1364
01:49:35.067 --> 01:49:40.000
to close with one keen Comsat --

1365
01:49:40.000 --> 01:49:46.000
Key concept. Can they change
their status when they

1366
01:49:46.000 --> 01:49:48.000
get their data?

1367
01:49:48.000 --> 01:49:51.000
Can you remind everyone in the
audience when can they get data

1368
01:49:51.000 --> 01:49:54.000
when they change your status?

1369
01:49:54.000 --> 01:50:00.000
>> This is Emmy. Definitely
don't wait until the five year

1370
01:50:00.000 --> 01:50:06.000
review these are made annually,
at a minimum once per

1371
01:50:06.000 --> 01:50:11.000
year, Boone you want to talk
about earlier than once per
year?

1372
01:50:11.000 --> 01:50:15.000
>> Sure. There are some we are
required to

1373
01:50:15.000 --> 01:50:21.000
update the status annually, even
if the status

1374
01:50:21.000 --> 01:50:25.000
site retains the status, we want
to make sure that we are
updating

1375
01:50:25.000 --> 01:50:30.000
the date with any new
information.

1376
01:50:30.000 --> 01:50:36.067
Updating the status if
necessary. Any

1377
01:50:36.067 --> 01:50:41.000
point if you have sufficient
data or

1378
01:50:41.000 --> 01:50:46.000
need sufficient data, to
investigate any new pathways

1379
01:50:46.000 --> 01:50:50.000
in the case of groundwater, any
new

1380
01:50:50.000 --> 01:50:55.000
migrating plumes, go ahead make
that status change as soon

1381
01:50:55.000 --> 01:51:00.000
as possible. As soon as you have
that new sufficient information.

1382
01:51:00.000 --> 01:51:06.000
We want to get if there are site
white

1383
01:51:06.000 --> 01:51:12.000
-- Wide changes you want to get
them out as much as possible.

1384
01:51:12.000 --> 01:51:18.000
This is a good time to check
back, since

1385
01:51:18.000 --> 01:51:24.000
these typically happen at the
end of the

1386
01:51:24.000 --> 01:51:27.000
cleanup process.

1387
01:51:27.000 --> 01:51:29.000
On other side, where there is
work being done continuously, go
ahead

1388
01:51:29.000 --> 01:51:34.067
make these status changes as
soon as you feel you have
submission

1389
01:51:34.067 --> 01:51:39.000
data to back up your new
determination.

1390
01:51:39.000 --> 01:51:53.000
>> Any other questions?

1391
01:51:53.000 --> 01:52:01.000
>> This is Emmy. I was following
up

1392
01:52:01.000 --> 01:52:07.000
on the request for the updated
fact sheet

1393
01:52:07.000 --> 01:52:12.000
ready for a reuse, that
performance measure, the last
one

1394
01:52:12.000 --> 01:52:21.000
2004. the 2020 update, should be
posted on a

1395
01:52:21.000 --> 01:52:23.000
website EPA website soon.

1396
01:52:23.000 --> 01:52:29.000
There will be a 2020 update we
can share the

1397
01:52:29.000 --> 01:52:34.067
SWRAU website with today's
group, if you want to click back
there,

1398
01:52:34.067 --> 01:52:39.000
as soon as that is ready they
will make it available publicly.

1399
01:52:39.000 --> 01:52:43.000
>> Will do Emmy thank you.

1400
01:52:43.000 --> 01:52:47.000
>> I want to be sure before we
close out with final reminders

1401
01:52:47.000 --> 01:52:52.000
there were a number of site
specific questions or scenarios
earlier

1402
01:52:52.000 --> 01:52:57.000
we mentioned the audience can
reach out if they had specific
questions,

1403
01:52:57.000 --> 01:53:01.000
I want to be sure all presenters
are okay, the audience that they

1404
01:53:01.000 --> 01:53:05.000
have them they can contact you
directly?

1405
01:53:05.000 --> 01:53:11.000
>> Sure this is Emmy.

1406
01:53:11.000 --> 01:53:15.000
And Boone we will be happy to
answer questions, I just want to
caveat

1407
01:53:15.000 --> 01:53:20.000
if it is a site specific
decision, EPA headquarters will
not preempt

1408
01:53:20.000 --> 01:53:25.000
the region, if you are

1409
01:53:25.000 --> 01:53:30.000
not with EPA hopefully you are
engaging in that conversation.
If you are,

1410
01:53:30.000 --> 01:53:34.000
you need some help definitely
fill free to reach out to us we
will

1411
01:53:34.000 --> 01:53:38.934
help you guide through that
logic

1412
01:53:38.934 --> 01:53:41.934
and determination.

1413
01:53:41.934 --> 01:53:46.934
>> This is Boone I'm happy to
answer any questions, there

1414
01:53:46.934 --> 01:53:51.934
are regional EI coordinators for
resource as well, and you can

1415
01:53:51.934 --> 01:53:57.934
check in with them pretty
regularly, they can

1416
01:53:57.934 --> 01:54:01.934
often answer the same questions
and they have deeper
understanding

1417
01:54:01.934 --> 01:54:07.934
of the site that you're working
on.

1418
01:54:07.934 --> 01:54:12.934
