The contact person for the facility is Sherri Palmer at (443) 738-9921 or [email protected].
The applicant has requested that enforceable limitations on the operation of the portable concrete plant be established in the permit pursuant to 20 DCMR §§ 200.7 and 201. Specifically, the applicant has requested an operating hour limit for the CEMCO 150 plant and its associated onboard engine (Plant Gen #1) at the site of 3,120 hours per 12-consecutive-month rolling period. Limits on the concrete production rate of 100,000 cubic yards in any 12-consecutive-month period have also been requested for the plant.
Factoring in these operational limits, the following is an estimate of the overall potential emissions from the facility:
FACILITY-WIDE EMISSIONS SUMMARY [TONS PER YEAR] |
|
Pollutants |
Potential Emissions with Limits |
Sulfur Dioxide (SO2) |
0.32 |
Oxides of Nitrogen (NOx) |
4.96 |
Fine Particulate Matter (PM Total) |
1.78 |
Volatile Organic Compounds (VOCs) |
0.42 |
Carbon Monoxide (CO) |
1.08 |
With the operational limitations included in the draft permit, the Schuster Concrete Ready Mix LLC facility has the potential to emit approximately 4.89 tons per year of oxides of nitrogen (NOx), which is below the District’s major source threshold of 25 tons per year of NOx. Similarly, all other pollutants’ potential emissions are below their respective major source thresholds. As such, the facility is properly classified as a minor source and is not subject to 20 DCMR § 300.1.
Emission Limits:
The following units are being permitted through this permitting action. After each table of units, the proposed emission limits are specified.
Portable Concrete Mixing Plant: One (1) portable temporary portable concrete plant with an associated boiler with a heat input rating of 2.1 MMBTU per hour:
