CEMCO 275 Truck Mix Concrete Plant
ELBA EMC85VAS Central Mix Concrete Plant
One factory mounted (CEMCO) generator set powered by a 173 hp John Deere diesel engine, Engine Family BJDXL06.8116 (Model year 2011)
One MQ Power WhisperWattTM, Model DCA400SSI4F3, 320 kWe prime/336 kWe standby generator set powered by an Isuzu Model BQ-6WG1X 512.3 hp (382 kWm) Diesel Engine (Model year 2020)
One MQ Power WhisperWattTM, Model DCA400SSI4F3, 320 kWe prime/336 kWe standby generator set powered by an Isuzu Model BQ-6WG1X 512.3 hp (382 kWm) Diesel Engine (Model year 2021)
The contact person for the facility is Paul MacDonald at (302)-215-1029 or [email protected] .
The applicant has requested that enforceable limitations on the operation of the portable concrete plants and non-emergency generator sets be established in the permit pursuant to 20 DCMR § 201. Specifically, the applicant has requested an operating hour limit for all equipment at the site of 3,744 hours per unit per 12-month rolling period. Limits on the concrete production rate of 275 cubic yards per hour and 1,029,600 cubic yards in any consecutive 12-month period per plant have also been requested for Plant #1 and 109 cubic yards per hour and 408,096 cubic yards in any consecutive 12-month period for Plant #2.
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]
With the operational limitations included in the draft permit, the Miller & Long Co. facility has the potential to emit approximately 4.23 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.
The following units are being permitted through this permitting action. After each table of units, the proposed emission limits are specified.
Portable Concrete Mixing Plants: Two (2) portable temporary portable concrete plants with an associated boiler with a heat input rating of 3.5 MMBTU per hour:
Production Rate (cubic yd/hr)
a. Emissions of dust shall be minimized in accordance with the requirements of 20 DCMR 605 and the “Operational Limitations” of this permit.
Non-Emergency Generator Sets Powered by Compression Ignition Internal Combustion Engines (CI-ICE) subject to New Source Performance Standards (NSPS): Four (4) non-emergency generator sets powered by diesel-fired engines subject to NSPS (40 CFR 60) Subpart IIII as described in the following table:
