2°d Quarter 2024 Site Inspection
Dear Mr. Bock:
Please find attached the 2nd Quarter 2024 Site Inspection Report based on our observations during the site
visit on 06 JUNE 2024. This site presents only a few potential sources of stormwater pollution. The site
appears to be cleaner today than observed during previous inspections The several items of concern are
described on the checklists and in photographs.
Overall, this facility's employees are taking a proactive approach to pollution prevention and Permit
compliance. It is evident that effort is made to practice good housekeeping and spill prevention. The
boatyard has a lot of activity today and its understandable that some SWPPP items will not get frequent
attention. Some items continue to be a potential source of pollution:
• Wood blocks may be a source of Copper. Cover if feasible when not in use.
• Remind new tenants doing self-repairs to secure all of their hazmats and protect from
precipitation.
• Remind all sub-contractors of their duty to secure all hazmat containers and to reduce pollutant
sources from their work. Develop a Pollution & Spill Prevention Policy for subs and vendors.
Insert copy into Appendix F and email a copy to this Consultant.
• Hull work such as grinding, sanding, and painting will be performed over a ground tarp or filter
fabric. Source for ground tarps include htips://www.mutualindustries.net/product/nw80-non-
woven-geotextile-polypropylene-fabric-roll-300-ft-length-x-l5-ft-width or similar. Ground tarps
will be swept immediately after any hull work that produces residue or particles with debris
disposed daily into plastic bags then placed into a dumpster.
• Totes that are used to temporarily hold fuel (contaminated or otherwise) should be marked with
type of fuel, date contents were first accumulated, and name of vessel if assigned to a single
vessel. Markings can be made with chalk or grease pencil.
• Provide flam cabinets in repair shop and storage sheds to store shop-level containers of hazmats.
• Continue to sweep off the wash pad daily to remove hull and bottom paint residue. This residue
will be placed into plastic bags then disposed into the dumpster.
• Abandoned boats are present in the "bone yard". Ensure these boats are not leaking fuel or oily
water.
• Conduct weekly litter patrol along ditches from Core Creek Rd to ICW. A litter patrol will be
most efficient during low tide.
The majority of boat owners are doing a satisfactory effort to secure their paints, cleaners, oils, batteries
and other hazardous materials in weather-proof containments or under tarps. The use of ground tarps
(e.g., filter fabric) under boats that are undergoing hull scraping, sanding, cleaning, and/ or painting is
recommended. Where ground tarps are used,the edges must be secured against wind and the tarps swept

at least weekly and prior to storms to remove residue. Sweep the hull work residue into plastic bags then
dispose into the dumpster at the end of each work day.
Other areas of the site (e.g., storage buildings, paint shed) should be cleaned out of old, broken,
abandoned, and/ or unneeded items every six months. Improved good housekeeping will increase
employee efficiency and reduce the potential for spills and accidents. A clean site also encourages boat
owners to keep their work areas clean. Overall,the site was mostly clean and mostly debris-free today.
Continue to implement the BMPs indicated on Tables 4, 5, 5.1, and 5.2 — mark with • and date of
implementation'. For all additional, new, and improved BMPs implemented since January 2024, indicate
on Table 5.2.
Review Compliance Task Schedule (Year 2024) on Page vii in the SWPPP binder to ensure that all tasks
with a target date thru 06/30/24 are completed this month. Mark completed tasks with •and date.
The SWPP Team must meet within the next several days to discuss this report. After reviewing,
sign below, and then insert this entire report into Appendix F of the SWPPP notebook.
A second 3-ring binder may be used to hold reports and documents dated prior to 2023. Label
the binder"Appendix F - SWPPP Reports thru 12/2022".
We will perform the next site inspection in the 3rd Quarter 2024. In the meantime, if you have
any questions, please do not hesitate to call.
