Section 259.320 - Initial Assessment
Universal Citation: 8 IL Admin Code ยง 259.320
Current through Register Vol. 48, No. 12, March 22, 2024
a) The purpose of the initial site assessment is to develop an appropriate sampling and analysis plan based on the environmental conditions at the agrichemical facility. The specific objectives of the initial site assessment are to identify the following:
1) target
pesticides,
2) locations of potable
water supply wells,
3) the
classification of the groundwater underlying the site,
4) soil and hydrogeologic conditions based on
available information,
5) areas
that may be locations of past agrichemical contamination, and
6) whether the facility is located within a
delineated well head protection area, the minimum or designated maximum setback
zone, or a regulated recharge area of a potable water supply well.
b) The initial site assessment shall provide the following:
1) a listing of
target pesticides, which shall include all pesticides known or suspected to
have been released, on the basis of interviews with the owner and operator and
a site investigation by or under the supervision of a licensed professional
geologist, professional engineer or licensed industrial hygienist.
A) Unless affirmatively demonstrated that a
pesticide has not been stored, mixed or loaded on the site, all pesticides
listed in this subsection (b)(1)(A) shall be considered target pesticides.

B)
An applicant may elect to limit the agrichemicals, media (soil or groundwater)
or area included in a site assessment. If the site assessment is limited in any
way, the notice of closure shall be limited to the agrichemicals, media or area
included in the site assessment and any corrective actions;
2) facility site maps, at a scale
no larger than 1 inch equals 200 feet, of sufficient detail and accuracy to
show all of the following:
A) areas of the
site that involve the storage or mixing and loading of agrichemicals,
B) site structures or buildings,
C) roads or driveways and parking
facilities,
D) the location of the
potable water supply for the site and any groundwater monitoring wells on the
site, and
E) the map scale (graphic
and nominal), north arrow, date, name and address of preparer, and location of
the site with respect to section, township, range, and principal
meridian;
3) a map, at a
scale no larger than 1 inch equals 400 feet, that shows the facility boundaries
and all of the following:
A) land uses (e.g.,
residential, commercial/industrial, agricultural and conservation property)
within 200 feet of the site boundaries,
B) any potable water supply wells within 200
feet of the site boundaries, and
C)
the map scale (graphic and nominal), north arrow, date, name and address of
preparer, and location of the site with respect to section, township, range,
and principal meridian;
4) a soil survey map of the site and the
surrounding area within 200 feet of the site and soil interpretation for each
soil series identified on the site or within 200 feet of the site for:
A) soil physical and chemical
properties,
B) engineering index
properties, and
C) soil and water
features;
5) copies of
lithologic and construction logs for any monitoring well or potable water
supply well on or within 200 feet of the site. If copies are not available, the
applicant shall provide:
A) an explanation as
to why such data could not be obtained,
B) estimations of the diameter and total
depth of each well, the screened interval of each well and the depth to water
in each well, and how those values were determined, and
C) an estimation of the geologic conditions
at each well site;
6)
U.S. Geological Survey 7.5 minute topographic map showing the location of the
facility, any community water supply wells within 2,500 feet of the site
boundaries and the boundaries of any delineated well head protection area, the
minimum or designated maximum setback zone or regulated recharge area for a
community water supply well;
7) any
pertinent reports containing hydrologic or geologic information by the Illinois
State Water Survey, Illinois State Geological Survey or U.S. Geological
Survey;
8) copies of prior site
assessments and any pending, threatened or past litigation, administrative
actions or notices from government entities regarding the storage or disposal
of pesticides at the site; and
9) a
detailed sampling and analysis plan including the following:
A) proposed number and location of soil
samples,
B) total sampling depth
and sampling depth intervals for soil samples,
C) locations and construction details for any
proposed monitoring wells and any existing monitoring wells or water supply
wells proposed for groundwater sampling,
D) list of analytes, analytical methods and
expected detection limits in soil and water, and
E) quality assurance project plans for field
and laboratory activities.
