Development for 316(b) PIC & CDS
NRG Energy, Inc.
Montville, Norwalk Harbor and Devon, CT
In 2005, Kleinschmidt was contracted by NRG Energy Inc. to develop
a Proposal for Information Collection (PIC) and three supporting reports
for the Devon, Montville and Norwalk Harbor stations located in Connecticut.
Devon Station is an
oil/gas-fired
plant located on the lower Housatonic River. Montville
Station is located on the estuarine portion of the Thames River and Norwalk
Harbor is located on the shore of Long Island Sound.
PIC
Preparation of the PICs has typically included a screening level strategic assessment to identify those options and rule alternatives that achieve compliance yet have the least impact on plant operations and the lowest overall cost.
In developing the NRG PICs, Kleinschmidt included the following information to address the specific provisions of 40 CFR 125.95 (b)(1)(i-iv):
- description of the design and operation of the cooling water intake systems;
- review of the specific criteria that determines applicability of the rule;
- summary of past studies of impingement and entrainment data;
- discussion of the collection of new impingement and entrainment data;
- summary of historical consultations with the State and Federal agencies;
- a preliminary review of technologies;
- the proposed compliance alternatives and measures to be evaluated in the Comprehensive Demonstration Study (CDS);
- description of methods to be used in support of the Site-Specific Best Technology Available (BTA).
Three Summary Reports
In addition to the PIC, Kleinschmidt developed the Source Water Physical Data Report, the Cooling Water Intake Structure Data Report and Cooling Water System Data Report. These reports provide fundamental background information as a basis for evaluating CWIS alternatives. The Source Water Physical Data Report includes a narrative with supporting maps and scaled drawings describing the physical characteristics of the source waterbody. The Cooling Water Intake Structure Data Report characterizes the intake and evaluates the potential for impingement and entrainment of aquatic organisms. Finally, the Cooling Water System Data Report characterizes the operation of the cooling water intake systems.
Comprehensive Demonstration Studies
Following completion of the PICs, Kleinschmidt has also been contracted to prepare the CDSs for the Montville and Norwalk Harbor Stations.
