WREG assisted a solution mining and mineral processing client in revising their Prevention of Significant Deterioration (PSD) permits to incorporate a number of substantive technology and emission changes that had occurred since the permits were originally issued. WREG performed dispersion modeling analyses for two widely separated portions of the source, including cumulative impact analyses. WREG also assisted the client in determining Best Available Control Technology (BACT) for a number of unique processes and emission units.
WREG was retained by the Pueblo Economic Development Corporation (PEDCo) to conduct an independent review of the Rio Grande Portland Cement Corporation’s Prevention of Significant Deterioration (PSD) permit application and the draft permit prepared by the Colorado Air Pollution Control Division (APCD). The PSD permit application was submitted for a new Portland cement plant in Pueblo County. The review was conducted to provide insight to PEDCo on the PSD permitting process associated with the proposed new facility and an assessment of how the issues raised during the public review process had been addressed.
WREG has helped a decorative light pole manufacturer with permitting and with Maximum Achievable Control Technology (MACT) compliance. The plant produces and paints fiberglass light poles. The operations are subject to two MACT standards: 40 CFR 63, Subpart PPPP—National Emission Standards for Hazardous Air Pollutants for Surface Coating of Plastic Parts and Products, and 40 CFR 63, Subpart WWWW—National Emission Standards for Hazardous Air Pollutants: Reinforced Plastic Composites Production.
WREG has prepared tools to help the company determine and track compliance with operating permit and MACT conditions. WREG has also assisted with preparation of a permit modification application to add base mold manufacturing operations to the facility and with preparation of an application to renew the facility’s operating permit. WREG also prepared documentation needed to relocate the plant to a new site in Colorado.
WREG has assisted a Colorado bottle manufacturing facility with several permitting actions, including:
- Minor modification permit application and self-certification package for a furnace rebuild, including Reasonably Available Control Technology (RACT) analyses for volatile organic compounds (VOCs) and fine particulate matter (PM10).
- Operating permit renewal application and Compliance Assurance Monitoring (CAM) plans. Requirements added from recent construction permits, parts washing tank requirements added, emission unit removed, insignificant activities updated, and CAM plan prepared for materials storage silos.
- Quality Assurance Plan for continuous emission monitoring system, including nitrogen oxides (NOx), sulfur dioxide (SO2), and oxygen (O2) monitors.
WREG assisted a metal beverage container facility with upgrades at its Colorado facility. The project involved the replacement and upgrade of equipment, and changes in the inks, coatings, and cleaners used. The project required two major Prevention of Significant Deterioration (PSD) modification applications. WREG prepared the permit applications, including Best Available Control Technology (BACT) review for volatile organic compounds (VOCs) and air quality dispersion modeling for nitrogen oxides (NOx). A detailed vegetation impact analysis was conducted for ozone. WREG also assisted with permit condition negotiations.
