Proposed Air Quality Permits 7112 through 7114, Wardman Hotel LLC, Modification and Operation of three existing 29.29 (gas)/30.31 (oil) MMBTU/hr dual fuel-fired (natural gas and No. 2 fuel oil/diesel fuel) boilers at the Washington Marriott Wardman Park

Friday, July 22, 2016

Department of ENERGY and Environment


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 permits (Nos. 7112, 7113, and 7114)  to Wardman Hotel LLC to modify and operate three identical Cleaver Brooks dual fuel-fired (natural gas and No. 2 fuel oil) boilers with a heat input of 29.29 MMBtu/hr when burning natural gas and 30.31 MMBtu/hr when burning No. 2 fuel oil, located at the Washington Marriott Wardman Park, 2660 Woodley Road NW, Washington, DC. The boilers currently exist at the facility, but they are being modified to fire No. 2 fuel oil instead of the heavier No. 4 fuel oil they currently fire.  The contact person for the facility is Tim Prager, Director of Engineering Facilities, at (202) 328-5681.

Three Identidal Boilers as Follows to be Permitted:


Equipment Location 


Boiler Size

Boiler Model #

Permit Nos.

Basement Level of Building

2660 Woodley Road

Washington, DC 20008

29.29 MMBtu (natural gas)  30.31 MMBtu/hr (No. 2 fuel oil)


7112, 7113, and 7114


The proposed emission limits are as follows:

a.       Each of the boilers (identified as Boiler #1, Boiler #2 and Boiler #3) shall not emit pollutants in excess of those specified in the following table [20 DCMR 201]:




Short-Term Limit

(Natural Gas) (lb/hr)

Short-Term Limit

(No. 2 Fuel Oil) (lb/hr)

Carbon Monoxide (CO)



Oxides of Nitrogen (NOx)



Total Particulate Matter (PM Total)*



Volatile Organic Compounds (VOC)



Sulfur Dioxide (SO2)



*PM Total includes both filterable and condensable fractions.

No limit is being established for VOC from No. 2 fuel oil combustion.

b.   Visible emissions shall not be emitted into the outdoor atmosphere from this boiler, except that 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, adjustment of combustion controls, or malfunction of the equipment [20 DCMR 606.1].

c.   Particulate matter emissions from the boiler shall not be greater than 0.08 pounds per million BTU. [20 DCMR 600.1]

d.      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]

e.       Emissions shall not exceed those achieved with the performance of annual combustion adjustments on each boiler for each fuel as specified in Condition III(c) and (d) and with the following characteristics [20 DCMR 805.8(a) and (b)]:

1.      Inspection, adjustment, cleaning or replacement of fuel burning equipment, including the burners and moving parts necessary for proper operation as specified by the manufacturer;

2.      Inspection of the flame pattern or characteristics and adjustments necessary to minimize total emissions of NOx and , to the extent practicable, minimize emissions of CO;

3.      Inspection of the air-to-fuel ratio control system and adjustments necessary to ensure proper calibration and operation as specified by the manufacturer; and

4.   Adjustments shall be made such that the maximum emission rate for any contaminant does not exceed the maximum allowable emission rate as set forth in Condition II(a)..

The estimated maximum potential emissions from each of the boilers are as follows:



Maximum Annual Emissions Using Exclusively Natural Gas (tons/yr)

Maximum Annual Emissions Using Exclusively No. 2 Fuel Oil (tons/yr)

Carbon Monoxide (CO)



Oxides of Nitrogen (NOx)



Total Particulate Matter (PM Total)



Volatile Organic Compounds (VOC)



Sulfur Dioxide (SO2)



The application to construct and operate the boilers and the draft set of 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:
