NOTE: This guide specification covers the requirements forcollection and analysis of environmental samples during
maintenance dredging
a storm water pollution prevention plan as required by NPDES General Permit. See Additional Note B. This guide
specification is to be used in the preparation of project specifications in accordance with ER 1110-2-1200.
This guide specification is required for all construction projects that disturb over 2 hectares (5 acres) of land
surface area which could be a source for erosion and sediment pollution due to storm water runoff.
A Notice of Intent (NOI) must be prepared and sent to the appropriate state licensing office or USEPA Regional
Office. At this time, it has not been determined when to send in the NOI, but it must be done after preparation
of a storm water pollution prevention plan, and perhaps after award of the contract because the names of the Contractors
must be give on the NOI.
After construction is completed, a Notice of Termination (NOT) must be sent to the state office or Regional USEPA
Regional Office.
Facilities which discharge storm water associated with industrial activity from construction activities must include
in their storm water pollution prevention plan the procedures and requirements specified in applicable sediment
and erosion plans, site permits, or storm water management plans approved by State or local officials that are
applicable to protecting surface water are, upon submittal of an NOI for coverage under this permit, incorporated
by reference and are enforceable under this permit even if they are not specifically included in a storm water
pollution prevention plan required under this permit.
Discharges seeking alternative permit requirements shall submit an individual permit application in accordance
with Part I.C of the permit to the Director, along with a description of why requirements in approved State or
local plans or permits should not be applicable as a condition of an NPDES permit.

PART 2 PRODUCTS (NOT USED)
PART 3 EXECUTION
3.1 ADVANCED MAINTENANCE AREA SAMPLING
3.1.1 General
Sediment samples must be taken [in Lake Michigan from the Waukegan Harbor Advanced Maintenance Area] after dredging and sediment disposal operations
are complete. No sediment samples shall be taken from a location which has been dredged to project depth as a part of this contract.[ The Waukegan
Harbor Advanced Maintenance Area is adjacent to the Approach Channel and East of the North Breakwater (see project drawings).] The sediment in
this area is sand, so the sampling equipment needs to be appropriate for this material such as a clam shell dredge. This sampling requires the
Contractor to maneuver a vessel and employ sediment sampling equipment to collect samples from three (3) different pre-determined sampling locations
posessing one to five (1-5) feet of shoaling. The vessel must have the capacity to seat two Government representatives as extra passengers. The
vessel requires a depth indicator and GPS unit to help assess shoaling and provide guidance to the pre-determined sampling locations (see Table
1 and Figure 1). The vessel must also have the capability to be completely stabilized prior to sampling to ensure that the vessel does not drift
and the sampling equipment can be utilized repeatedly at the same location, if necessary. The use of a spud barge would be appropriate for these
conditions. Samples must be collected, handled, preserved and analyzed in accordance with publications listed in the EPA 600/4-79/020, EPA SW-846.3-3
and ASTM D422. The Contractor must collect sufficient amount of sample to perform all the laboratory analyses outlined in this paragraph. The
Contracting Officer's Representative must be notified one week in advance of scheduled sampling date so that a Government representative may be
present at the site during sampling operations. The Contracting Officer Representative must also be notified of changes to sampling scheduling
date as soon as possible.
3.1.2 Sampling
No sediment samples must be taken from a pre-determined sampling location which falls within an area dredged to project depth as a part of this
contract. The sediment samples from each shoaled location must be representative of the column of material, and the sample must include the material
from the top of the sediment surface down to a depth of twenty-four (24) feet below Low Water Datum (LWD). The project depth is 22 feet below
LWD. For shoaling to be present, the top of the sediment surface must be higher than the project depth, and then the amount of shoaling is the
distance from the top of the sediment surface down to the project depth. Due to inaccuracies of the dredging processes, typically an additional
two (2) feet of over-depth dredging below project depth are allowed. Therefore in order to remain representative, sediment samples must include
the entire depth of material, from the top of the sediment surface down to a depth of twenty-four (24) feet below LWD. Depth must be measured
by checking the NOAA website to determine the lake level with respect to LWD, then in the field using a weighted tape measure to measure the depth.
If there is insufficient shoaling at a pre-determined sampling location, the vessel must then proceed sequentially to the next pre-determined sampling
location, until a location where one (1) foot or more of shoaling is reached. The Contractor must document the date and time of the sampling and
the sample depth below LWD at each location. The Contractor must also document the measured latitude/longitude of the sample locations using GPS
or other approved technology and name the corresponding pre-determined sample location. All information on the date, times, depths, and locations
of the samples must be reported in the Field Log and be submitted to the Government for approval, as required in paragraph "SEDIMENT SAMPLING FIELD
LOG".
3.1.3 Sediment Sampling Procedure
The Contractor maneuvers the vessel to the pre-determined sampling location using the GPS unit and completely stabilizes it prior to sampling.
Once a predetermined sampling location has been found with sufficient shoaling, a sediment sample is collected. See paragraph "Sampling" for how
to determine shoaling. Small sediment samples are collected from throughout the column of sediment, and these sub-samples are placed in a large
stainless steel mixing bowl. When the collection of sub-samples is complete, the remainder of the sediment from that sample is emptied away from
the original sampling spot and the sampling equipment is lowered again to the site of the original sample. The Contractor must evenly distribute
any sediment returned to the water to avoid the artificial creation of additional shoaling. This procedure is repeated until a depth of twenty-four
(24) feet below LWD is reached. If the sampling equipment is lowered and no noticeable change in depth is seen on the depth indicator of the sampling
equipment, then the sample load must be lifted and dumped without sampling to avoid re-sampling sediment that has collapsed back into the original
hole. Once the complete sample has been acquired, the sediment is homogenized in the mixing bowl and placed into different containers for testing.
The vessel must proceed to the next pre-determined sampling location and repeat this process until all three (3) samples have been collected.
The Contractor must collect an amount of sediment sufficient to perform all analyses outlined in this section.
3.1.4 Sampling Schedule
The Contractor must coordinate the sample collection date with the Contracting Officer Representative at least one (1) week prior to the proposed
sampling date. Sediment samples must not be collected until dredging and disposal operations have ended and sediment samples must not be taken
from locations which have been dredged to project depth. Sampling must not be performed if there are adverse weather conditions, such as high
wind and waves. Locations of sediment sampling must be coordinated with the Contracting Officer Representative prior to sample collection date.
3.1.5 Sample Analysis
Laboratory analysis of samples must include the parameters listed in Table 2. This table also shows the required reporting limits for analysis
and reporting. The laboratory must meet the required reporting limits. The three (3) sediment samples must be analyzed for asbestos, Total PCBs,
and grain size. The asbestos testing needs to be performed using both polarized light microscopy (PLM) and transmission electron microscopy (TLM)
methods. Grain size must be performed in accordance with ASTM D422, employing a No. 230 sieve. In addition to ASTM D422, particle size analysis
must be conducted using the IEPA procedures for Material Analysis for Dredge and Fill Activities (See Attachment #1). A composite sample of the
three advance maintenance area samples must be created by the laboratory. The composite sample must be used for the supernatant analysis and must
be analyzed for the appropriate set of parameters listed in Table 2. The supernatant testing on the composite sample must be based on both zero
hour and four hour settling periods. The sample must have a 1:4 ratio of sediment to natural background water (vol./vol.) using water collected
from near-shore Lake Michigan at the reference site. The concentrations for supernatant analyses need to be reported in mass per unit volume.
See supernatant procedure requirements in accordance with Attachment #1.
3.2 BACKGROUND SAMPLING
3.2.1 General
Two (2) water samples and three (3) sediment samples must be colleced from the Illinois Beach State Park reference site. Reference site sampling
is done to compare the quality of the dredged material to the material at the disposal site. Previous disposal operations have taken place offshore
of Illinois Beach State Park so it is important that samples are not collected from areas of prior disposal. The portion of Illinois Beach State
Park reference site to be used for this sampling is an area commonly referred to as North Beach and is located directly north of North Point Marina
and directly South of the Illinois/Wisconsin state line. The location of the reference site as well as the general locations of past disposal
operations can be found on Figure 2. The Contractor must collect sufficient amount of sample to perform all the laboratory analyses outlined in
this paragraph. The Contracting Officer's Representative must be notified one week in advance of scheduled sampling date so that a Government
representative may be present at the site during sampling operations. The Contracting Officer Representative must also be notified of changes
to sampling scheduling date as soon as possible.
3.2.2 Sediment Sampling
A total of three (3) surface grab samples must be collected from the reference site. These samples must be taken approximately 300 feet from each
other near to the water's edge. Samples are to be collected from below the water surface, to avoid beach debris such as bird waste and vegetation.
The Contractor must collect sufficient amount of sample to perform all the laboratory analyses outlined in this paragraph. The Contractor must
document the date and time of the sampling at each location. The Contractor must also document the measured latitude/longitude of the sample locations
using GPS or other approved technology. All information on the date, times, and locations of the samples must be reported in the Field Log and
must be submitted to the Government for approval, as required in paragraph "SEDIMENT SAMPLING FIELD LOG".
3.2.3 Water Sampling
Two (2) water samples must be collected from one near-shore Lake Michigan location at the Illinois Beach State Park reference site. The volume
of water to be collected must be determined by the laboratory. The water samples must be field tested for pH and temperature and must be reported
in the Field Log as required in paragraph "SEDIMENT SAMPLING FIELD LOG".
3.2.4 Reference Site Sample Analysis
Laboratory analysis of samples must include the parameters listed in Table 2. This table also shows the required reporting limits for analysis
and reporting. The three (3) reference site sediment samples must be analyzed for asbestos, Total PCBs, and grain size. See paragraph "Sample
Analysis" for asbestos and grain size testing requirements. One (1) water sample must be directly analyzed for the appropriate parameters listed
in Table 2. The second water sample must be used in the supernatant analysis. See paragraph "Sample Analysis" for supernatant testing requirements.
3.3 SAMPLE PRESERVATION AND CONTROL
3.3.1 Samples
All samples must be placed in non-contaminating containers provided by the Contractor. Either before or immediately after filling, all containers
must be properly labeled to include the sample location, date, and time of collection. If a sample requires the addition of a preservative, it
must be added immediately using a solution made from fresh reagent stock. Samples must be maintained at a temperature less than 4°C until analyses
are performed.
3.3.2 Chain of Custody
Proper chain of custody documentation must accompany the collected samples. The chain of custody must contain the sample numbers, analyses to be
performed on each sample, the time and date of transfer, the condition of the samples, and the signature of each person involved in the transfer
of samples. The chain of custody must be placed in a water-resistant plastic bag and securely attached to the inside lid of the cooler. Indelible
ink must be used on the container labels and chain of custody. The chain of custody documentation must be included in the Final Report.
3.4 LABORATORY TURNAROUND TIME
The results from measurements using field instrumentation, for pH and temperature, must be submitted via email no later than one day following
the day when the measurements were performed as required in paragraph "SEDIMENT SAMPLING FIELD LOG". The QC results, calibration checks, all laboratory-generated
QC acceptance criteria, and final analytical results must be submitted within 30 days of sample receipt as required in paragraph "FINAL REPORT".
3.5 LABORATORY REQUIREMENTS
Submittals of the laboratory results must be in accordance with the "Submittals" paragraph of this section. The Contractor must use the services
of an analytical laboratory that has been accredited in accordance with The NELAC Institute's National Environmental Laboratory Accreditation Program
(NELAP). The laboratory must be accredited for the Clean Water Act (CWA) and Resource Conservation and Recovery Act (RCRA) fields of testing.
The following web site has a list of NELAP laboratories and their accredited fields of testing: http://www.nelac-institute.org then click on "NELAP
Accredited Labs".
3.6 LABORATORY QUALITY CONTROL
3.6.1 Batch of Samples
Laboratory quality control must include calibration checks, method blanks, matrix spike, matrix spike duplicate, surrogate recoveries, laboratory
control samples, and laboratory control samples duplicates. The Quality Control (QC) results, sample results, calibration checks, and all laboratory-generated
QC acceptance criteria must be reported in the final report in accordance with the "Final Report" paragraph of this section.
3.6.2 Pre-Sampling Quality Assurance/Quality Control Meeting
A Pre-Sampling Quality Assurance/Quality Control meeting must be held after the sampling plan submittal is received but before sampling begins.
This meeting can be held as a conference call. The meeting will be attended by members of USACE - Chicago District, the Contractor performing
the field sampling, and at least one lab chemist/analyst from each of the Contractors' laboratories. The purpose of this meeting is to discuss
specific Data Quality Objectives required for this sampling project. Topics discussed at the meeting must include but not be limited to: sampling
methods and equipment, GPS location accuracy, decontamination methods, sample preservation and shipment, chain-of-custody procedures, laboratory
certification, holding times, analytical methods, required detection limits, types and frequency of QC samples, and case narratives. It is critical
that the laboratory personnel performing the physical and chemical testing of the samples be aware of the data quality issues associated with this
project. This analytical testing and analysis is to comply with a Clean Water Act Section 401 Water Quality Certification, so it is very important
that the laboratory produces data of known and acceptable quality. The Contractor must achieve the required reporting limits listed in Table 2
as these are permit requirements. The Contractor and the Contractors' laboratories must incorporate any QA/QC reporting requirements into their
protocol.
