The Division of Air Quality (DAQ) has received an air permit application for the proposed Middletown Technology Center, with a copy of the application and a map of the location posted below, along with other documentation:
- Presentations made at the Aug. 31, 2016 public workshop for the proposed Middletown Technology Center
- Air permit application for the proposed Middletown Technology Center
- Modeling supplement to application:
The Middletown Technology Center project includes installation of a data center and a power generation facility. The power generation facility will consist of five 10-megawatt (MW) and five 2.5-MW natural gas-fired reciprocating engines, each limited to 3,300 hours per year of operation. Emissions from the engines will be controlled by pollution control equipment. Selective catalytic reduction (SCR) will be used to reduce emissions of nitrogen oxides by 95 percent. Oxidation catalysts will be used to reduce carbon monoxide (CO) emissions by 93 percent, volatile organic compound (VOC) emissions by 50 to 82 percent, and formaldehyde emissions by 80 to 90 percent. The project will also contain a 40,000-gallon-per-minute counter-flow cooling tower.
The facility will normally be powered by purchasing electricity from the grid. DAQ has been informed that operation of the engines is only intended for three situations:
- Power outages due to grid failure (i.e., when both feeds to the site are down)
- When the electricity supplier asks for support for grid stability, and
- When it is economically advantageous (expected during periods of high demand - i.e. during periods of extremely cold or very hot weather).
If a permit is issued, it will require the company proposing to build the Middletown Technology Center, Cirrus Delaware LLC, to meet strict air quality standards under the Federal Clean Air Act and Delaware regulations. To ensure regulatory requirements are fulfilled, DNREC's Division of Air Quality will conduct a rigorous environmental permit process that includes detailed technical review of the application and development of permit conditions that are necessary and appropriate to protect the environment and public health from risk or harm. DNREC will not issue permits that allow emissions that can cause a condition of air or water pollution.
Steps that DNREC's Division of Air Quality will take in processing the proposed Middletown Technology Center application:
- DAQ is currently evaluating the application and starting preparation of a draft permit. Given the significant interest the project has already generated, DAQ will accept comments on the application during a 30-day period ending April 29, and will consider these comments in producing the draft permit. Please submit comments to DAQPERMITTINGINFO@state.de.us with "MTC" on the subject line.
- After the draft permit is prepared, DAQ will advertise it over another 30-day comment period on the permit and application in newspapers, on the DNREC website and via other departmental communications. At this time the public will also have an opportunity to request a DNREC public hearing, at which interested parties may comment or express concerns about the project.
- If a hearing is requested, please note that the requester must show a familiarity with the application and a reasoned statement of the permit’s probable impact; If the hearing is held, DNREC will provide the usual 30-day notice and will work with local officials to ensure that the hearing is held in a location that is convenient for interested parties, particularly for local residents of the area for which the project is proposed.
- All comments received on the application, draft permit, or hearing will be considered before any final permitting action is taken.
