Dear Mr. Horn:
BROWNS FERRY NUCLEAR PLANT (BFN) NPDES PERMIT NO. AL0022080 SEDIMENTATION POND - DISCHARGE SERIAL NO. 102 This is a follow up to my February 24 and March 25 letters to you regarding the repair of the sedimentation pond at BFN. This is our report on how the sedimentation pond was originally constructed. the extent of the repairs, and the results of the testing to determine the success of the repairs.
The pond was constructed around 1970, as part of a two pond system for treating metal cleaning wastes. Concentrated wastes were initially pumped to a lined pond, and then subsequently pumped to the sedimentation pond where they were diluted with river water prior to discharge. After BFN went into operation in 1974, wastewaters from the water treatment plant were also routed to the sedimentation pond. These wastes originated from the regeneration of the resin beds and filter backwash.
The pond received this type of waste until March 1987, when the water treatment facility was removed from service. Since that time, a mobile water treatment facility (Ecolochem Inc.) has been providing demineralized water for BFN. The waste from this facility consists of filter backwash which contains alum, and is currently being routed to the lined pond while the sedimentation pond is out of'ervice.
The sedimentation pond was built as a nonpermanent facility with a clay layer approximately two feet thick. The quality of the construction material was poor. The current repair work started on December 21, and concluded on February 10, During the excavation, it became apparent that the material used to originally construct the dike was not properly engineered after numerous stumps, rocks, and pipes were discovered in the dike.
