~ PALISADES NUCLEAR PLANT ~
1991 ANNUAL NON RADIOLOGICAL ENVIRONMENTAL OPERATING REPORT 1:0 BACKGROUND Appendix B to the Facility Operating License Number DPR-20 for the Palisades Nuclear Plant, Consumers Power Company, is entitled, "Environmental Protection Plant (Non Radiological)". This document requires Consumers Power Company to submit to the Nuclear Regulatory Commission an annual environmental operating report prior to May I which describes implementation of the Environmental Protection Plan during the previous year. The period covered by this report is January 1, 1991 to December 31, 1991.
Palisades operated for 6845.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> during 1991 producing a net total of 4,873,835 MWH. This represents 72.2% of the net demonstrated capacity for 1991.
2.0 ENVIRONMENTAL IMPACT EVALUATIONS Several revisions to procedures and modifications to the facility were evaluated using the environmental evaluation guideline form for impact
- on the environment during 1991. There were 47 procedures or modifications to the facility reviewed by Consumers Power Company Environmental Department for impact on the environment. Of the 47.
procedures or modifications reviewed by the Environmental Department, 3 required approval or permits from the Michigan Department of Natural Resources. The three processes are summarized in Section 2.1, 2.2 and 2.3.
2.1 FC-864 Dry Storage of Spent Fuel Received approval from the Michigan Department of Natural Resources (MDNR) to remove sand from the Palisades site for installation of a concrete pad to store fuel in casks. The sand was removed from an area designated as critical sand dunes under the Sand Dune Protection and Management Act (PA 146 of 1989). Prior to the sand removal as required by the
.Environmental Protection Plan, the area was inspected for presence of the Pitcher's Thistle. The Pitcher's Thistle is a threatened and endangered species, and has been previously identified in the Palisades Plant general area. There was no evidence of* the Pitcher's Thistle in this area. A permit under Act 146 was issued by MDNR on March 12, 1991 and will expire on March 12, 1992.
2.2 Betz Clam-Trol I (CT-I) Treatment of Service Water System and Circulating Water System Palisades received permission from the Michigan Department of Natural Resources to use Betz Clam-Trol 1. CT-I is a molluscicide/biocide used for the eradication of zebra mussels present in the Palisades ser~ice water and circulating water systems. Palisades added Betz Clam-Trol I to the service water and circulating water system on July 23 and October 9, 1991. These treatments wer* successful in reducing the zebra mussel population.
2.3 Ma~Condenser and Feedwater Syste~ush and Chemical Clean (T-310)
Palisades received authorization from the Michigan Department of Natural Resources to discharge waste water generated from the removal of copper from the feedwater and condensate system during February 1991. The copper was removed from the two systems using ammoniated water and a mobile demineralizing system which was used for cleanup.
There was no adverse impact to the environment.
3.0 ADDITIONAL ACTIVITIES AUTHORIZED UNDER NPDES 3.1 A revised National Pollutant Discharge Elimination System (NPDES) permit was issued in August, 1991. The revisions to the permit are summarized as follows:
- a. Provisions were added to the permit to allow for continuous chlorination, with a maximum chlorine concentration to Lake Michigan of .036 ppm total residual chlorine. Continuous chlorination can be used as a zebra mussel deterrent. An NPDES permit revision was required prior to using this method.
- b. The short term boron waste characterization study was deleted from the permit. Palisades was scheduled to perform a boron waste discharge study during one month of each quarter for one year beginning July 1, 1991 to July 1, 1992. The characterization study was no longer needed since the plant's use of boron was revised due to the replacement of the plant's steam generators and information about the effects of discharging small amounts of boron did not warrant additional characterization.
3.2 Activity under the NPDES permit for the.groundwat~r remediation project of the old fuel depot did not occur during 1991. (NPDES permit #MI0049131) 4.0 UNUSUAL ENVIRONMENTAL EVENTS There were no unusual environmental events in 1991.
5.0 ENVIRONMENTAL MONITORING 5.1 Meteorological monitoring to document effects of cooling tower operation on meteorological variables was required for two years following conversion to the cooling towers. The cooling towers have been in operation for.17 years.
There were no activities in this area ~uring 1991.
5.2 Herbicide Application Herbicides were applied to the transmissi~n corrid9r as shown in Attachment A.
6.0 NON-ROUTINE REPORTS There were no Non-Routine Reports generated in 1991.
. 7.0 MISCELLANEOUS-IRONMENTAL ACTIVITIES e 7.1 Concrete test weights used during the steam generator replacement outage were buried in the overflow parking lot.
These test weights were used to form a berm between the Van Buren State Park and the contractors laydown area on company property. Dune grass was planted on the berm and pine trees were planted in the area to improve the site aesthetics.
7.2 On July 10, 1991 @ 0830, a loss of sewage into a storm drain system occurred. Approximately 200 gallons of liquid sewage flowed into a storm drain located in the northwest corner of the main parking lot. There was no evidence of sewage present at the end of the storm drain (Outfall 004). This event was reported to Michigan Department of Natural Resources on July 10, 1991 @ 1455.
7.3 On August 20, 1991 an undetermined amount of diluted hydrazine was accidentally discharged from the plant via the turbine sump into the mixing basin. Upon discovery of the release of diluted hydrazine to NPDES Outfall 001, grab samples of the mixing basin were obtained. The mixing basin grab samples indicated less than 10 ppb hydrazine.
The Michigan Department of Natural Resources was notified on August 20, 1991 of the discharge of hydrazine. This event did not result in a NPDES violation nor was there any adverse affect to the environment.
7.4 There was one NPDES exceedence on December 10, 1991. The Oil &Grease maximum outfall concentration of 20 ppm was exceeded. The sample obtained contained 58.4 ppm oil &
grease. The source of the oil & grease wa~ identified and corrected. The Michigan Department of Natural Resources was notified of this incident on December 11, 1991.
