Friday, January 8, 2016


Proposed Air Quality Permits 7044 and 7045, Roubin and Janiero, Inc., One crusher and one conveyor with associated diesel engines at the asphalt plant at 4901 Shepherd Parkway SW

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, intends to issue air quality permit Nos. 7044 and 7045, respectively, to the Roubin & Janeiro Inc. to operate one crusher powered by a 350 horsepower Caterpillar engine and one conveyor powered by a 49 horsepower Caterpillar engine at the Roubin & Janeiro Hot Mix Asphalt Plant located at 4900 Shepherd Parkway SW, Washington, DC 20032. The contact person for the facility is Joe Roubin, Vice President, at (703) 491-9100.

The proposed emission limits are as follows:

  1. Emissions from the engine shall not exceed those found in the following table, as measured according to the procedures set forth in 40 CFR 89, Subpart E. [40 CFR 89.112(a)]

Emission Limits                         Crusher                    Conveyor

















  1. Emissions of dust shall be minimized in accordance with the requirements of 20 DCMR 605 and the “Operational Limitations” of this permit.
  1. 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]

d.   Emissions from the engine powering the crusher/conveyor shall not exceed those achieved by proper operation of the equipment in accordance with manufacturer’s specifications.

e.   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]

f.    In addition to Condition II(e), exhaust opacity from the engine, measured and calculated as set forth in 40 CFR 86, Subpart I, shall not exceed [40 CFR 89.113]:

1.   20 percent during the acceleration mode;

2.   15 percent during the lugging mode;

3.   40 percent during the peaks in either the acceleration or lugging modes. Note that this condition is streamlined with the requirements of 20 DCMR 606.1.

g.   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]

The estimated emissions from the crusher engine are as follows:


Emission Rate (lb/hr)

Maximum Annual Emissions (tons/yr)

Carbon Monoxide (CO)



Oxides of Nitrogen (NOx)



Total Particulate Matter (PM Total)



Volatile Organic Compounds (VOCs)



Oxides of Sulfur (SOx)



The estimated emissions from the conveyor engine are as follows:


Emission Rate (lb/hr)

Maximum Annual Emissions (tons/yr)

Carbon Monoxide (CO)



Oxides of Nitrogen (NOx)



Total Particulate Matter (PM Total)



Volatile Organic Compounds (VOCs)



Oxides of Sulfur (SOx)



In addition to the above, total particulate emissions from the material handling aspects of the crusher and conveyor are 0.741 tons per year.

The applications to operate the crusher and conveyor with their associated engines and the draft permits and supporting documents are available for public inspection at AQD and copies may be made available between the hours of 8:15 A.M. and 4:45 P.M. Monday through Friday.  Interested parties wishing to view these documents should provide their names, addresses, telephone numbers and affiliation, if any, to Stephen S. Ours at (202) 535-1747.

Interested persons may submit written comments or may request a hearing on this subject within 30 days of publication of this notice.  The written comments must also include the person’s name, telephone number, affiliation, if any, mailing address and a statement outlining the air quality issues in dispute and any facts underscoring those air quality issues.  All relevant comments will be considered in issuing the final permit.

Comments on the proposed permit and any request for a public hearing should be addressed to:
