PUBLIC NOTICE
Notice Requesting Public Comment on Draft Air Quality Construction and Operation Permits for Miller & Long Co., Inc. – 5300 South Dakota Avenue NE Site

Notice is hereby given that, pursuant to 20 DCMR § 210, the Air Quality Division (AQD) of the Department of Energy and Environment (DDOE), located at 1200 First Street NE, 5^th Floor, Washington DC, intends to issue permit Nos. 7333 through 7337 to Miller & Long Co., Inc to operate two (2)  concrete batch plants and three (3)  non-emergency generator sets, powered by diesel-fired engines, to be located at 5300 South Dakota Avenue NE, Washington DC.

Units to be Permitted

Emission Unit ID	Unit Description	Location	Assigned Chapter 2 Permit Number
Plant #1	CEMCO 275 Truck Mix Concrete Plant	5300 South Dakota Avenue NE	7333
Plant #2	ELBA EMC85VAS Central Mix Concrete Plant	5300 South Dakota Avenue NE	7334
Plant Gen # 1	One factory mounted (CEMCO) generator set powered by a 173 hp John Deere diesel engine, Engine Family BJDXL06.8116 (Model year 2011)	5300 South Dakota Avenue NE	7335
Gen #1	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)	5300 South Dakota Avenue NE	7336
Gen #2	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)	5300 South Dakota Avenue NE	7337

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]
Pollutants	Potential Emissions with Limits
Sulfur Dioxide (SO2)	4.61
Oxides of Nitrogen (NOx)	4.23
Coarse Particulate Matter (PM10)	3.23
Fine Particulate Matter (PM2.5)	0.68
Volatile Organic Compounds (VOCs)	0.46
Carbon Monoxide (CO)	13.93

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.

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 Plants: Two (2) portable temporary portable concrete plants with an associated boiler with a heat input rating of 3.5 MMBTU per hour:

Emission Unit ID	Equipment Location	Concrete Plant Model	Production Rate (cubic yd/hr)	Permit No.
Plant #1	5300 South Dakota Avenue NE Washington DC 20011	CEMCO 275	275	7333
Plant #2	5300 South Dakota Avenue NE Washington DC 20011	ELBA EMC85VAS	109	7334

Emissions Limitations:

a.   Emissions of dust shall be minimized in accordance with the requirements of 20 DCMR 605 and the “Operational Limitations” of this permit.

2. The emission of fugitive dust from any material handling, screening, crushing, grinding, conveying, mixing, or other industrial-type operation or process is prohibited. [20 DCMR 605.2]
3. The discharge of total suspended particulate matter (TSP) into the atmosphere from any process shall not exceed three hundredths (0.03) grains per dry standard cubic foot of the exhaust. [20 DCMR 603.1]
4. The discharge of TSP from the portable concrete plant shall not exceed 40 pounds per hour. [20 DCMR 603.1 and Appendix 6-1]
5. TSP emission from the No. 2 fuel-fired boiler shall not exceed 0.13 pound per million BTU of heat input. [20 DCMR 600.1]
6. Visible emissions shall not be emitted into the outdoor atmosphere from stationary sources; provided, that the discharges not exceeding forty percent (40%) opacity (unaveraged) shall be permitted for two (2) minutes in any sixty (60) minute period and for an aggregate of twelve (12) minutes in any twenty-four-hour (24 hr.) period during start-up, cleaning, soot blowing, adjustment of combustion controls, or malfunction of the equipment. [20 DCMR 606.1]
7. An emission into the atmosphere of odorous or other air pollutants from any source in any quantity and of any characteristic, and duration which is, or is likely to be injurious to the public health or welfare, or which interferes with the reasonable enjoyment of life or property is prohibited. [20 DCMR 903.1]

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:
