Limetick Generating Station NPDES Permit No. PA0051926 The following information is being provided, as per your request, to update the subject NPDES permit application.

: l. We would like the functional description of the holding pond (monitoring point 201) to be changed to read: "Non-hazardous / industrial wastes generated as part of routine plant operations, testing, and maintenance, including, at a minimum, plant cooling water, closed cooling water (sodium nitrite / nitrate), mop / wash water, stand-by liquid control system test water (residual sodium pentaborate and demineralized water), rainwater, approved treatment chemicals, and chemical reagents / products utilized in the site chemistry labs. Holding pond discharge to outfall 001 can be either a batch or continuous process." Please note that this does not reflect a change in plant operations or conditions. The listed processes were in place during the last permit application and the subsequent effluent characterization. We feel this description better details the processes involved. | |||
In addition, concerning the question of the water treatment plant discharge and regenerative wastes, the only wastewater going to the holding pond from the water treatment plant are from the clarification process. No regenerative wastes are discharged to the holding pond. Also, no photographic wastes are discharged to the holding pond. Photographic wastes were contained in .the origina description of the holding pond due to activities occurring during the construction of the plant. Please remove photographic waste from the holding pond description. | |||

On average, the expected discharge would be 5,000 gallons per day, with a maximum discharge rate of 150,000 gallon per day (this only occurs jun before start-up until the tower basin expands due to plant heat).
