Curtis Building 6th and Walnut Streets Philadelphia, Pennsylvania 19106 011 Spill Questionnaire - VA-84_-156 - 5/18/84 florth Anna Power Station, L_ou i s a. Vj rgi n i a_

Dear Mr. Voltaggio:

Enclosed is the completed spill questionnaire (flo. VA-84-156 -

5/18/84 florth Anna Power Station) for the oil spill that occurred at our florth Anna Power Station on May 18, 1984.

As noted in the questionnaire an oil sheen was observed by station personnel in the afternoon, of May 18, 1984, in the condenser cooling water disciarge canal from the oil separator (f1POES Outfall 004). The exact source of the oil could not be determined. All levels in the oil separator were normal and it was known to be functioning properly. Surveillance of the area was maintained for the next few days but no additional discharge was observed.

The oil was contained by an absorbent boom and removed from the lake surface using absorbent materials. Due to the small amount of oil involved and prompt action by station personnel to cleanup the spill, no adverse impact to the environment was noted.

If you desire any additional infonnation, please contact us.

Very uly your,s, .,

u. In the past few months the Cor.pany has undertaken severc projects to [

prevent oil spills to either North Anna Lake, the dischar :e canal, or the Waste Heat Treatment Facility. The folicwing is a pa: tial list of those projects.

1. One man has been assigned the task of inspecting all li.317 sources of oil spills. Further, he has been given the task of i.suring all spill cleanup is thorough and complete.

2. Work has begun to remove and replace all oil stained or socked soil with clean fill. i

3. Work has begun to construct and.use a waste oil storage area with a  ;

concrete floor and berms.  !

4. The oil / water separator has been inspected, cleaned, and adjust?d in accordance with the suggestions made by a representative of the oil /

water separator manufacturer during a site visit in the spring of 1983.

5. A study has been completed that re-examined the design and flow cLarac-teristics of the oil / water separator. Results of the study show tr.at the separator is operating properly.

6. The station has purchased, installed, and is using several oil skimmers to remove any oil that might accumulate in sumps within the station.

7. A drum managament plan has been developed and implemented on site. Th3 plan addresses the contents of the drums on-site, as well as the locatian, handling, and storage or disposal of these materials. In this way oil  :

and other materials on site are better tracked and utilized.

8. An evaluation has been completed of the establishment of satellite, emergency oil spill control stations on-site. This evaluation consider-ed the need, location, and equipment needed in the event a spill occurs and also considered the history of oil spills at the site. Stations are currently under construction and will be placed within the next'two ,

months.

9. The station Spill Prevention Control and Countermeasures Plan and the Cencral Employee Training program (required annually), are being revised t to further emphasize and eliminate the problems that contribute to oil to further emphasize and eliminate the problems that contribute to oil spills. The training program has been updated to include spill recogni-tion and centrol.

10. The station is contracting for concrete oil collection basins to be placed at five critical storm drain outfalls. These basins will be monitored daily.
