Draft / Proposed Air Emission Permit

Prairie Lakes Municipal Solid Waste Authority
Comment Period Begins For Draft/Proposed Air Emission Facility Permit
On Perham Incinerator Expansion Project; Public Meeting Planned March 25, 2013
for Perham Resource Recovery Facility Expansion

NOTICE IS HEREBY GIVEN, that the Commissioner of the Minnesota Pollution Control Agency (MPCA) proposes to issue Air Emission Permit No. 11100036-004, to Prairie Lakes Municipal Solid Waste Authority for their facility located at 201 6th Avenue Northeast, Perham, Otter Tail County, Minnesota.

The proposed permit action will authorize modification and operation of the facility. This proposed permit action is a total facility operating permit re-issuance which also includes a major amendment, parameter re-openings, and administrative amendments. Hence, the draft/proposed permit has been placed on public notice. The major permit amendment is rolled into the re-issuance for the proposed expansion of the facility. The parameter re-openings are based on previous performance test conditions. The administrative amendments involve the change of ownership/operation of the facility (City of Perham to Prairie Lakes Municipal Solid Waste Authority). The MPCA is seeking the U.S. Environmental Protection Agency's (EPA) concurrent review of this draft/proposed permit and the EPA 45-day review period will begin with the 45-day public review period.

The proposed expansion project will include the addition of a heat recovery boiler and associated air pollution control equipment dedicated the South Incinerator Unit (EU 001). The pollution control equipment will consist of dry lime injection, activated carbon injection, and a fabric filter. Other than being debottlenecked by the current facility expansion, the North Unit (EU 002) will remain unchanged as part of the expansion project, continuing to be associated with the existing heat recovery boiler and air pollution control equipment. After the project, both waste combustor units will be able to concurrently operate up to 100 tons per day, individually, up from the current 116 tons per day total for both units. Exhaust gases will enter the atmosphere through a new single 125-ft. tall primary stack. Exhaust gases will continue to be continuously monitored for CO, SO2, opacity, and O2. A number of operating parameters, including fabric filter inlet temperature, steam flow rate, and activated carbon feed rate parameters will also continue to be monitored continuously.

Moreover, this permit action includes the following. State-only mercury emission limits for the two existing incinerators (EU 001 and EU 002) will be added (41.0 ug/dscm). A state-only total dioxin/furan limit for the existing North Incinerator (EU 002) will be added (20.0 ng/dscm).

Upfront of the combustion process, the facility proposes to construct and operate a Materials Recovery Facility (MRF). This operation will be housed with the waste combustors. The operation of the MRF will include:

- Identifying and removal of problem materials;
- Removal of recyclables, such as aluminum, ferrous metals, and cardboard; and.
- Separation and removal, from the fuel supply, undesirable waste and fines.

The MRF is designed to process all incoming waste.

The preliminary determination to issue the air emission permit is tentative. There are four formal procedures for public participation in the MPCA's consideration of the permit application. Interested persons may (1) submit written comments on the draft/proposed permit; (2) request that the MPCA hold a public information meeting; (3) request the MPCA hold a contested case hearing; and/or (4) submit a petition to the Commissioner requesting that the MPCA Citizens' Board (Board) consider the permit matter.

The decision whether to issue the permit and, if so, under what terms, will be presented to the Board for decision if: (1) the Commissioner grants the petition requesting the matter be presented to the Board; (2) an Board member requests to hear the matter prior to the time the Commissioner makes a final decision on the permit; or (3) a request for a contested case hearing is pending. Otherwise, the Commissioner will make the decision.

Persons who submit comments or petitions to the MPCA must state (1) their interest in the permit application or the draft permit; (2) the action they wish the MPCA to take, including specific references to the section of the draft permit they believe should be changed; and (3) the reasons supporting their position, stated with sufficient specificity as to allow the MPCA to investigate the merits of the position.

As for the second formal procedure, Prairie Lakes Municipal Solid Waste Authority has already requested the MPCA hold a public information meeting. On Monday, March 25, at 6:30 p.m. the MPCA will hold the public information meeting. The meeting will be held in the Perham City Council Chambers, 125 2nd Avenue Northeast, Perham, Minnesota. The public information meeting will provide information, receive public input, and answer questions about the proposed permit.

As described in Minn. R. 7000.1800, persons who submit requests for a contested case hearing must also state the issues they propose to address in a contested case hearing, the specific relief requested or resolution of the matter, and the reasons (which may be in the form of proposed findings) supporting an MPCA decision to hold a contested case hearing. Failure to comply with these rules exactly may result in a denial of the request. The decision whether to hold a contested case hearing will be made under Minn. R. 7000.1900. Most public libraries throughout the state have copies of the current Minnesota Rules. They are also available on the Internet at www.revisor.leg.state.mn.us.

The public comment period commences February 22, 2013, and terminates April 8, 2013. Comments must be received in writing at the MPCA by 4:30 p.m. on April 8, 2013. Evidence of timely receipt includes a date/time stamp imprinted on the first page of the written comments by support staff, or receipt by fax.
