1501 State Implementation Plan for reasonably available control technology; Delaware County Regional Water Quality Control Authority; proposed revision  

  • State Implementation Plan for Reasonably Available Control Technology; Delaware County Regional Water Quality Control Authority; Proposed Revision

    [44 Pa.B. 4599]
    [Saturday, July 19, 2014]

     The Department of Environmental Protection (Department) is providing notice in accordance with 40 CFR 51.102 (relating to public hearings) that it intends to conduct a public hearing on August 20, 2014, at 1 p.m. in the Delaware Conference Room at the Department's Southeast Regional Office, 2 East Main Street, Norristown, Montgomery County.

     The public hearing is being conducted to solicit public comments on a revision to the State Implementation Plan (SIP), as codified at 40 CFR Part 52, Subpart NN (relating to Pennsylvania). The affected part of the SIP is the Reasonably Available Control Technology (RACT) plan for Delaware County Regional Water Quality Control Authority's (DELCORA) (P. O. Box 999, Chester, PA 19016), Western Regional Treatment Plant located in the City of Chester, Delaware County.

     TVOP 23-00038 regulates two multiple hearth incinerators at DELCORA's facility. A RACT permit, OP-23-0032, codified in the SIP for the Commonwealth, is incorporated in TVOP 23-00038. The proposed SIP revision corrects an error in the heat release limit for each hearth incinerator at the facility.

     The United States Environmental Protection Agency (EPA) approved DELCORA's RACT determination as a SIP revision at 65 FR 78418 (December 15, 2000). The RACT requirements for volatile organic compounds (VOC) and nitrogen oxides (NOx) specified in Operating Permit OP-23-0032 (as revised May 16, 1997), approved by the EPA as a SIP revision, are codified at 40 CFR 52.2020(c)(143)(i)(B)(2) (relating to identification of plan). Condition 17 of OP-23-0032, pertaining to the heat release limit for each incinerator, was erroneously included as a RACT limit in the SIP revision. The heat release limits were not part of the RACT determination because they were based on evaluations for the initial facility operating permits, including 23-301-084 which precedes the RACT permit.

     The Department is proposing to remove the heat release limitation of 43.4 million British thermal units per hour for each incinerator from the RACT SIP revision because the limits were erroneously included in the approved SIP revision.

     The Department has concluded that the heat release limit is not necessary for NOx and VOC emission restrictions. It should be noted that the RACT limits on NOx and VOC emissions at the facility remain unchanged. The company has justified removal of the heat release limit to the Department by presenting stack test data to the Department that indicates that emissions are dominantly affected by the amount and characteristics of the sludge burned rather than the total heat release in the incinerator. The Department is seeking public comment on this proposed SIP revision.

     Concomitantly, the Department has issued DELCORA a modified Operating Permit with the heat release limitations removed as well as a decreased NOx limitation to 15.0 lb/hr and 65.7 tons/year for each incinerator. This modified Title V Operating Permit correctly includes the December 15, 2000 NOx RACT emissions limits incorporated in 40 CFR 52.2020(c)(143)(i)(B)(2).

     Persons wishing to present testimony at the hearing should contact the Department Community Relations Coordinator Lynda Rebarchak at (484) 250-5820 or lrebarchak@pa.gov to reserve a time. Persons who do not reserve a time will be able to testify as time allows. Witnesses should keep testimony to 10 minutes and should provide two written copies of their statement at the hearing. Notice of the proposed SIP revision will also be published in newspapers of general circulation.

     Persons with a disability who wish to attend a hearing and require an auxiliary aid, service or other accommodation to participate in the proceeding should contact Lynda Rebarchak at the number or e-mail listed previously. TDD users may contact the Pennsylvania AT&T Relay Service at (800) 654-5984 to discuss how the Department can best accommodate their needs.

     If by Monday, August 18, 2014, no person has expressed an interest in testifying at the hearing, the hearing will be cancelled. The Department will provide public notice on the Bureau of Air Quality web page at www.dep.state.pa.us/dep/deputate/airwaste/aq/default.htm if the hearing is cancelled. Persons may also contact the Department to find out if the hearing is cancelled.

     Those who are unable to attend the public hearing may provide written comments to James Rebarchak, Regional Manager, Air Quality, Department of Environmental Protection, Southeast Regional Office, 2 East Main Street, Norristown, PA 19401 or jrebarchak@pa.gov. Include ''DELCORA SIP Revision'' in the subject line and provide the name, affiliation (if any), mailing address and telephone number of the person submitting the comments. The Department must receive written comments no later than August 22, 2014.
