Inspection Summary:
Site Walk
I meet Kelly Tackett (Plant Manager)at the site and we reviewed the site.There is a AST for fueling onsite equipement that
is double walled and located under a shelter. I noted the need for an SOP of approved fuel loading and dispensing methods.
Documentation requirements noted in summery of SP3 review.
There are a few buildings on site with one being used as a service are for the occasional vehicle. There are vehicles in the
shop building at this time and there are large oil spills on the concrete that have had absorbent applied, but that have not
been cleaned up and properly stored for removal. All spills or leaks should be cleaned up as soon as possible. Applying
absorbent is the proper way to prevent the spread or tracking of the material, but the spill should be cleaned up and
containerized for disposal as soon as possible and not left.
The facility proposes to crush and sell used concrete once they have acquired enough on site to begin crushing. They have
a pile of a few hundred tons so far.They also sell stone that has been shipped in from off site, no mining takes place on site.
The stone is loaded using a wheel loader and this is the only working equipment on site at this time.
SP3 Review
Most of the required documents for the SP3 are at the facility already from the previous permit(NCG020088). The SP3
should be modified for the new permit and its new operation and parts of the plan should be updated
The Preventive Maintenance and Good Housekeeping portion of the plan (PM&GHP)should be tailored for the facility in a
site specific manner. Each area that has the potential for spills or leaks and are capable of polluting the stormwater in some
way should have a specific PM&BHP. The fueling area would have a plan that discusses the potential for spills while
unloading fuel to the AST and what can be done to prevent incidents and a plan in cause there are spills or leaks. The same
dispensing fuel to the equipment. There should be procedures for properly dispensing fuel to the equipment and a plan of
what to do if there is a spill or leak. Each area should have a specific checklist for the quarterly sampling. The fueling areas
focus should be leaks, staining from spills and damaged or worn dispenser lines. Whenever something is noted as an issue
there should be a plan or time table for cleanup or repair.
The shop area should have a PM&GHP that looks at spills, leaks and improperly stored or handled chemicals or materials
and the proper method and timeline for cleanup and disposal of spills and leaks along with storage and handling procedures.
That should be part of the PM&GHP for the shop along with anything else that is applicable. The quarterly inspection should
provide a checklist for all these things-spills or leaks that haven't been cleaned up, improperly stored and handled materials
for the different areas in the shop. Any negative findings on the checklist should have a follow up response for when and how
the issue will be resolved.
The crusher that will be brought on site should have the same PM&GHP and inspection plan provided in the SP3
Training materials should be specific to the site. Be sure there is training for the best practice to identify and resolve
problems with damaged or worn hydraulic or fuel lines that will be a stormwater pollutant. How to watch for and address
leaking equipment, both heavy equipment and vehicles for company employees and customers and what to look for when
accepting off-site materials such as the used concrete (Petroleum or other products coating the concrete). Be sure the
incoming concrete is inspected as it comes in and provide a line in the inspection checklist for an inspection of what's on
site at that time.
There is one outfall on the site that very seldom if ever discharges. Any stormwater that doesn't infiltrate into the soil, pools
and evaporates.
