The inspectors met with onsite representative David Callahan for the inspection. Mr. Callahan provided all documentation required and gave the inspectors a tour of the facility and how it operates. The facility has a boiler which blows down about once every 24 hours. An oxygen scavenger, a polymer, and a streamline agent are still used in the boiler water. MSDS were available on site, and a copy of the new permit from 2020 and COC were available on site. Mr. Callahan stated that after there were 2 exceedences for residual chlorine in 2017, they switched to using liquid chlorine in 2020 to keep these exceedences to a minimum. This has helped them stay within their limits since making this change. Boiler blowdown water is pH adjusted with sulfuric acid and is recirculated in a tank to allow for cooling and proper pH adjustment. They have a pH probe for process control on the addition of sulfuric acid. Monitoring requirements are done by EnviroChem and a copy of their lab certification was available on site. COD, pH, and temperature were analyzed, as well as residual chlorine at least 2x/year. The water is allowed to cool in the tank while the pH is adjusted prior to discharge in to a drain which has a tiered flow setup as well as a "pom pom" for additional oil absorption from stormwater runoff. Estimated flow is -1000 gal/day. Daily logs were available for discharging and they included the dates, start/stop times, initials of discharge operator, and pH. No foam or oil sheen was present in the drain on the water surface. Facility looks well maintained and records were complete.
