Proposed Air Quality Permit 7088 - Providence Hospital

Friday, October 21, 2016

PUBLIC NOTICE

Proposed Air Quality Permit 7088, Providence Hospital, Construction and operation of one 24.80 MMBTU/hr dual fuel fired boiler at 1150 Varnum Street NE

Notice is hereby given that, pursuant to 40 C.F.R. Part 51.161, and D.C. Official Code §2-505, 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 #7088 to Providence Hospital to construct and operate a dual fuel-fired boiler rated at 24.80 MMBtu per hour heat input. The allowable fuels used in the unit will be No. 2 fuel oil and natural gas.  The boiler is to be located at the Providence Hospital Campus at 1150 Varnum Street NE, Washington DC 20017. The contact person for the facility is Marc Edelman, Senior Vice President, Operations, at (202) 854-7000. 

Emissions:

Maximum emissions from the unit are expected to be as follows:

                                                   

Maximum Annual Emissions

Pollutant

(tons/yr)

Total Particulate Matter (PM Total)

1.03

Sulfur Dioxide (SO2)

0.09

Oxides of Nitrogen (NOx)

4.90

Volatile Organic Compounds (VOC)

1.74

Carbon Monoxide (CO)

7.93

The proposed overall emission limits for the equipment are as follows:

  1. This 24.80 million BTU per hour (MMBTU/hr) dual fuel-fired boiler shall not emit pollutants in excess of the rates specified in the following table [20 DCMR 201]:

Boiler Emission Limits

Pollutant

 

Short-Term Limit
(Natural Gas)
(lb/hr)

Short-Term Limit
(No. 2 Fuel Oil) (lb/hr)

Carbon Monoxide (CO)

1.810

0.952

Oxides of Nitrogen (NOx)

0.868

2.808

Particulate Matter less than 10 microns in aerodynamic diameter (PM10)*

0.188

0.562

Sulfur Dioxide (SO2)

0.015

0.048

*PM10 includes both filterable and condensable fractions.

b.   Visible emissions shall not be emitted into the outdoor atmosphere from the 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.   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

d.   Total suspended particulate matter (TSP) emissions from the boiler shall not exceed 0.08 pound per million BTU. [20 DCMR 600.1]

  1. Emissions shall not exceed those achieved with the performance of annual combustion adjustments on the boiler for each fuel. To show compliance with this condition, the Permittee shall, each calendar year, perform adjustments of the combustion process of the boiler with the following characteristics [20 DCMR 805.1(a)(4) and 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;
  1. 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;
  1.  Inspection of the air-to-fuel ratio control system and adjustments necessary to ensure proper calibration and operation as specified by the manufacturer; and
  1. 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 permit applications and supporting documentation, along with the draft permit document 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:
