Inspection Summary:
Stormwater Pollution Prevention Plan
The stormwater pollution prevention plan (SP3) is still being revised. Cumminication and availability with consultantants is
paramount for meeting deadlines and maintaining compliance. Please make yourself available by phone or email when there
are questions or concerns by the consultant or the State. Some parts of the SP3 were reviewed briefly but for this site visit
our focus was on the site condition and corrective actions on site from the last inspection.
Site Walk Through
The diesel tank dispenser area had visible staining below the dispenser nozzle on the last inspection that appears to have
been cleaned up. Kreem Dudley the Plant Director advised us that a spill pan was being built to be placed in the area where
spills and leaks had previously occurred to prevent future spills on the ground in that area and to facilitate easy cleanup from
spills and leaks.A standard operating procedure should be developed for the off load of fuels from the vendor as well as an
SOP for the fueling of equipment. Both should be part of the SP3.A placard for both actions are recommended at the fuel
loading and fueling dispenser areas.
There are still some drums on site that should be stored safely under cover or in secondary containment when not in use.
There were two 55 gallon drums of cleaning fluid in one of the aggregate bays. The amount of stored liquid materials
exceeds the 1320 gallon max for multiple containers so its required that all liquid material vessels be in secondary
containment
Provide a locking valve on all secondary containment areas. The secondary containment should have only specific personnel
with key access and authorization to open. Those personnel should be properly trained on the required procedure for
draining the secondary containment.An SOP should be developed for that process and that SOP should be part of the SP3.
The maintenance shop must be added to the permit along with it's outfall. The maintenance shop should have its own SP3
that covers all the requirement of the permit including a narrative description of practices, PMGHP, inspection checklist,
employee training etc...
A facility checklist that is site specific should be developed that covers all the areas on site that have the potential to pollute
stormwater along with an inspection of all outfalls
An SOP should be developed for the gutter guard maintenance and should include a schedule that allows for the
replacement of guards before they get so full they don't function correctly. If the guards are found to be full when the site is
inspected in the future the state will have to include the outfalls as part of the outfall sample requirements. As long as the
guards are changed out regularly and not allowed to clog and cause the stormwater to bypass the outlet, that won't happen.
The street curb along the front of the facility should be swept to help alleviate the maintenance requirements and an SOP
should be developed for that that will dictate how often sweeping should occur once that time frame is established.
It is recommended that a berm be built across the entrance to the facility to divert stormwater toward the SDO-001 outfall
and help prevent gravel and dirt from washing into the road. Especially during large storm events. There have been numerou
complaints concerning materials washed into the street
Provide the manifest disposal of the petroleum cleaned up at the secondary containment area on the NE side of the property
and the large spill on the South side of the maintenance shop. The report of the spill cleanup for the maintenance shop
should be provided that delineated the size and depth of the material for cleanup. The report will list how much material was
removed, how it was moved and at what certified facility it was disposed of and on what date.All the cleanup efforts should
be listed I the SP3 in the spill log and the PMGHP.
The outfalls should be sampled as required and entered in the eDMR system and the original signed DMR must be sent to

Comment: The facility has there SP3 plan but it still hasn't been updated as required by their inspection
report from November 17, 2023. The maintenance shop has not been included in the permit as
requested on 11/17/2023 so all the require information for that part of the facility hasn't been
