Notice of Public Hearing and Public Comment Period
Proposed Air Quality Permit 7188, Superior Concrete Materials, Inc., Construction and operation of a ready mix portable concrete batch plant , 1721 South Capitol Street SW

Air Quality Permit for Superior Concrete Materials, Inc.

Notice is hereby given that, pursuant to 40 C.F.R. Part 51.161, D.C. Official Code §2-505, and 20 DCMR §210, the Air Quality Division (AQD) of the Department of Energy and Environment (DOEE), located at 1200 First Street NE, 5th Floor, Washington, DC, is proposing to issue an air quality permit (#7188) to Superior Concrete Materials, Inc. to construct and operate a ready mix portable concrete batch plant at 1721 South Capitol Street SW, Washington DC, 20003. This plant will replace the existing Superior Concrete Materials, Inc. plant located at 1601 South Capitol Street SW, Washington DC, 20003. The contact person for the applicant is Roberto Talavera, Director of Technical Services/Operation, at (301) 343-7660.   

Emissions Estimate:

The maximum potential emissions from the proposed facility have been developed assuming maximum allowable operations of 4,200 hours per year, operating at the facility’s maximum rated capacity of 240 cubic yards of concrete per hour. Based on these assumptions, emissions are not expected to exceed 11.0 tons per year of total particulate matter. Of this particulate matter, approximately 4.7 tons per year is expected to have an aerodynamic diameter less than ten microns (PM10).

Emission Limits:

The proposed emission limits for the facility are as follows:

  1. Emissions of dust shall be minimized in accordance with the requirements of 20 DCMR 605 and the “Operational Limitations” of the 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 concrete batch plant shall not exceed 40 pounds per hour. [20 DCMR 603.1 and Appendix 6-1]
  5. Visible emissions shall not be emitted from the equipment covered by this permit except that discharges not exceeding 40% opacity (unaveraged) shall be permitted for two (2) minutes in any sixty (60) minutes period and for an aggregate of twelve (12) minutes in any twenty-four (24) hours period during start-up, cleaning, adjustment of combustion controls, or malfunction of the equipment. [20 DCMR 606.1]
  6. 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]
