5. FIELD EVALUATION & PLAN IMPLEMENTATION
The EPA Inspection Team observed sediment accumulation to the
height of the silt fence in the southern, southwestern, western,
and eastern portions of the Site [Refer to Appendix B,
Photograph Log (Photographs 15-17, 19-22, and 25)].
At the time of the inspection, the Site's sediment basin was under
construction, with two (2) of the four (4) planned inlets already
constructed. With the sediment basin still being under
construction, it was actively being used to collect surface flow
from the Site, with no stabilization present along the
No
embankments.
According to the EPSC, the sediment basin should have been completely constructed before being used to collect and treat stormwater [Refer to Appendix B, Photograph Log (Photographs 5-7, and 9)]. The EPA Inspection Team observed that the southwestern corner of the Site had sediment accumulation with no EPSCs present [Refer to Appendix B, Photograph Log (Photograph 18)].
No The EPA Inspection Team observed a constructed channel that went from the sediment basin pump to the Site's perimeter silt fence. The manmade channel's discharge point was being used as the outlet for the sediment basin pump. No pollutants were observed in the discharged waste at the time of the inspection [Refer to Appendix B, Photograph Log (Photographs 11 and 12)]. The Operator had not installed a stabilized construction entrance or other sediment control at the site entrance/exit off Fite Road[Refer to Appendix B, Photograph Log (Photograph 1)].
No Sediment track out was observed leaving from the Site onto Fite Road from the construction entrance/exit [Refer to Appendix B, Photograph Log (Photograph 1)].
The EPA Inspection Team observed one (1) pump at the sediment
basin for the removal of excess water from the basin. The pump
discharged to the southeast into a constructed channel, which
Yes
then discharges to an open field further southeast. No pollutants
were observed in the discharged waste at the time of the
inspection [Refer to Appendix B, Photograph Log (Photographs
10-12)].
No No temporary or permanent stabilization was observed during the inspection. Page 5 of 8
stabilized within 14 days? (permit section 3.5.3.2) If yes, describe below each location and measures taken to stabilize the area(s). g. Have pollution prevention measures been installed, implemented, and maintained to minimize the discharge of pollutants from wash waters, exposure of materials and discharges from spills and leaks per section 4.1.4? If "No," describe below the measure to be implemented to address deficiencies. h. If a concrete washout facility is located on site, is it clearly identified on the project and maintained? If "No," describe below the measures to be implemented to address deficiencies. i. Have all previous deficiencies been addressed? If "No," describe the remaining deficiencies in the Comments section.
j. Silt Fences
k. Storm Drain Inlet/Outlet Protection (Specify: Filter Fabric, Gravel Bags, etc.)
5. FIELD EVALUATION & PLAN IMPLEMENTATION
The EPA Inspection Team did not observe any pollution N/A prevention measures since the Operator was not washing or
servicing equipment or storing materials with the potential to spill or leak at the time of inspection.
N/A
No concrete washout facility was observed during the inspection.
There was no Site representative or previous inspection report No documentation onsite; therefore, the EPA Inspection Team was
unable to review previous inspection reports to identify previous deficiencies and corrective actions taken.
Silt fences were observed installed at the site at the time of the
inspection, but not at all identified locations in the EPSC plan.
No
Refer to the "Are all applicable EPSCs installed and maintained
per the SWPPP per the current phase?" section for more
information on the condition of the silt fences.
One (1) inlet on the northwestern portion of the Site, between the northernmost wetland and the construction entrance off Fite No Road before the railroad crossing, was unprotected and was surrounded with accumulated sediment. The EPSC indicated that the inlet should have protection in the form of a mineral aggregate mound surrounding it [Refer to Appendix B,
Page 6 of 8
5. FIELD EVALUATION & PLAN IMPLEMENTATION Photograph Log (Photograph 23)].
l. Construction Entrance & Exit Controls
One (1) inlet in the center portion of the Site had sediment
deposited over the silt fence protection and into the inlet. The
EPSC plan indicated that the inlet protection is a mineral
aggregate mound surrounding the inlet [Refer to Appendix B,
Photograph Log (Photograph 8)].
The EPA Inspection Team observed one (1) construction entrance
off Fite Road. However, this entrance was not identified in the
Site EPSC Plans [Refer to Appendix B, Photograph Log
No
(Photograph 1)] [Refer to Appendix C, Exhibit Log (Exhibit 1)].
Moreover, the EPSCs observed at this site were not functioning to
prevent sediment tracking from the Site onto Fite Road [Refer to
Appendix B, Photograph Log (Photograph 1)].
m. Truck Wash Down Controls
N/A A truck wash down area was not present at the Site at the time of the inspection.
n. Concrete truck washout pit
At the time of the inspection, concrete work was not being done
N/A
at the Site and no concrete washout pits were present at the
inspection.
o. Other Practices (e.g., fueling containment, control areas for maintenance, etc.)
N/A
None present at the time of the inspection.
p. Proper Storage & Control

Water
a. Number & location of stormwater N/A discharge(s)/outfall(s) consistent with the Plan
The EPA Inspection Team, despite walking the perimeter of the Site, was not able to confirm the specific number and locations of stormwater outfalls because there was no on-site representative.
b. Evidence of off-site accumulation of sediment observed in receiving water
The EPA Inspection Team walked the perimeter of the Site and X observed no evidence of off-site accumulation of sediment within
the receiving water during the inspection.
c. Non-stormwater X discharge observed
The EPA Inspection Team observed sediment discharge offsite in the southwestern, western, and eastern portions of the Site [Refer to Appendix B, Photograph Log (Photographs 17, 18, 19, and 20)].
Page 7 of 8
7. INSPECTION OBSERVATIONS AND AREAS OF CONCERN Observations
CGP, Part 5.5.3.1.c. states "[i]f sediment escapes the permitted area, off-site accumulations that have not reached a stream must be removed at a frequency sufficient to minimize off-site impacts (e.g., sediment that has escaped a construction site and collected in a street must be removed so that it does not subsequently wash into storm sewers and streams during the next rain..." The EPA Inspection Team observed evidence of sediment discharge offsite [Refer to Appendix B, Photograph Log (Photographs 17, 18, 19, and 20)].
The construction entrances were not installed to the Structural Practices section in the SWPPP [Refer to Appendix C, Exhibit Log (Exhibit 2)]. The detail specifies clean stone sizes from 2 inches to 4 inches to a depth of at least 8 inches, underlain with geotextile fabric. The EPA Inspection Team observed one (1) construction entrance along Fite Road that was not stabilized [Refer to Appendix B, Photograph Log (Photograph 1)]. Sediment track out was observed leaving from the Site onto Fite Road from the construction entrance/exit [Refer to Appendix B, Photograph Log (Photograph 1)].
SWPPP, Page 11 states "Sediment must be removed from sediment traps, silt fences, sediment basins and other sediment controls when design capacity has been reduced by 50%." The EPA Inspection Team observed silt fence with sediment accumulation that reduced the capacity of the control by at least 50% [Refer to Appendix B, Photograph Log (Photographs 15-17, 19-22, and 25)] [Refer to Appendix C, Exhibit Log (Exhibit 2)].
Exit interview conducted with: N/A, no onsite Site representative was present to conduct an exit interview.
