Inspection Summary:
Inspection was in response to permit renewal. Information included in the application is accurate. The application states that
the tin manufacturing process has been discontinued. Tin manufacturing was brought back. The facility has also added
some special metals manufactuing, like antimony, bismuth,nuTin, etc. Antimony and tin dust are combustable, so
manufacturing is contained and there should be no transfer of the dusts around the facility. The copper manufactuing that
takes place onsite does generate a lot of dust. There is a dust residue that gets tracked outside the facility by foot and
loader traffic. The facilty is also partially under construction so BMPs that have previously been regularly used are not as
effective, like tacky matts to prevent the copper dust being tracked outside. There is a dust collection system and the
copper dust is collected in an exterior bag house. The copper dust is deposited in a bag and the bag is monitored multiple
times a shift to prevent over flow. There is still a risk of exposure of the copper dust to stormwater if there is a bag
malfunction. Copper dust was observed tracked outside. It should be noted that the facility has an impressive list of BMPS
that are regularly implemented to deal with the dust. There are tanks and other materials stored outside at the rear of the
facility. Everything appeared to be stored correctly. There are several drop inlets in the paved lot at the rear of the facility
where there is storage. The drop inlets drain to an onsite bioretention cell. Water in the bioretention cell infiltrates into the
ground. If there is ever any overflow, the water for the riser in the bioretention cell is pipes to outfall 1. The facility uses a
street sweeper in the back parking lot to control copper dust. Used oil drums are stored under cover and in propper
secondary containment in the back lot. Construction materials are also stored temporarily in this back lot.
I recomend the site map be updated to show the bag houses, outdoor storage of tanks, used oil, raw materials, etc.
Continue sweeping activities to address the copper dust tracked into the back lot.
