In 1990, permitting regulations were developed by the U.S. Environmental Protection Agency (EPA) under the National Pollutant Discharge Elimination System (NPDES). These regulations control stormwater discharges under Sector F covers work with primary metals including steel works, blast furnaces, rolling and finishing mills, and nonferrous foundries.

Whatever the nature of your business, and the activities you engage in to run your business, you are at risk of releasing contaminants such as TSS, organics and heavy metals into the watershed. You need to stay in compliance. We can help you navigate these regulations. We get it and we have solutions.

PRODUCTS APPLICABLE TO THIS SECTOR

Our filtration systems are designed to remove many of the pollutants that your site can generate: TSS, heavy metals, oil and grease. Our treatment trains provide progressively cleaner water to maximize efficiency. The heart of our treatment systems for metal processing facilities is the Aquip® enhanced stormwater filtration system. Aquip® be may paired with our Clara® stormwater plug-flow separator or our Purus® stormwater polishing system for ultimate filtration results. Our systems work, and we have the track record to prove it. Many of our metal industry clients are repeat clients who refer other businesses to us.

Once your treatment system is installed, StormwateRx trains your staff to operate and maintain the equipment for the best results at the lowest cost. We follow up with inspection and maintenance service to ensure your treatment system operates at maximum efficiency and keeps you in compliance with changing regulatory requirements.

Metal, Metal Products & Machinery Sectors

ALUMINUM EXTRUSION COMPANY, Pacific Northwest

Sapa Group is an international extrusion, anodizing and fabrication company with 23 locations in the US, Canada and South America. Beginning in 2013, Sapa Group began undertaking a process to upgrade stormwater pollutant control infrastructure at three of its pacific northwest facilities. As a result of this initiative, the company has come into full compliance with industrial stormwater benchmarks at two of its facilities, and a third will have treatment installed in 2017. The first of the three facilities has been granted a monitoring waiver for all regulated stormwater pollutants.

METAL RECYCLING, OREGON

An ISO 14001 Certified Facility

Calbag Metals Co. is a 4-acre non-ferrous metal recycling facility located in Portland, Oregon. The metal recycling facility had been using catch basin inserts along with an oil/water separator and a cartridge filter with compost media, to treat the site’s stormwater prior to discharge.

GALVANIZING SITE

Emerald Galvanizing, Inc. includes approximately 8,700 square feet of paved area and a 4,300 square foot building. The stormwater collects at one catch basin and had discharged directly into Lake Union Ship Canal which flows into Puget Sound. The galvanizing site had been struggling to meet the stormwater benchmarks for zinc set forth by the facility’s Washington Industrial Stormwater General Permit.
