LG 166 - GUIDELINES FOR TESTING SPILL BUCKETS Enclosure 1 owners and operators should submit spill bucket test results (pass or fail) to the local UST regulatory agency within 30 days of the completion of the test . Additionally, UST owners and operators must maintain test results on- site or off- site at a readily available location, if approved by the local UST regulatory agency, for a period of at least three years , as is required by CCR, Title 23 , Section 2712(b) . Part IV : Management of Hydrostatic Test Fluids A . Classification of Test Fluid. Thorough cleaning of spill buckets prior to testing will minimize contamination of the test fluid . In order to reduce the amount of hazardous waste generated from hydrostatic spill bucket testing , the Department of Toxic Substances Control (DISC) recommends using new test fluid whenever possible . If the spill bucket is cleaned of all hazardous substance residues prior to the beginning of the test, the test fluid will typically not become hazardous waste . B . Reuse of Test Fluid . If all hazardous substance residue is not cleaned from the spill bucket prior to the beginning of the test , or if the test fluid is used or reused repeatedly and contaminants build up in the test fluid , then the test fluid may become hazardous . Test fluid that is reused is not considered to be waste pursuant to U. S . EPA' s " continued use " policy, provided that the test fluid is not disposed of, burned or incinerated , accumulated speculatively , or reclaimed . The hazardous waste generators shall determine if the test fluid is a hazardous waste . More information regarding hazardous waste determination can be found in CCR, Title 22 , Section 66262 . 11 . C . Leakage of Test Fluid. If the test fluid is reused and the test fluid leaks from the spill bucket during a test (i . e . , the test fails ) , or if it is otherwise accidentally disposed of to the environment , the hazardous waste generator must take all appropriate measures to address the release (e . g . , implement the facility' s emergency response/contingency plan) . D . Disposal and Transportation of Test Fluid . If the test fluid is reused , immediately following its final reuse, the generator must classify the test fluid pursuant to CCR, Title 22, Section 66262 . 11 . If the reused test fluid is hazardous waste , it must be managed in accordance with all applicable requirements . Hazardous waste generators may accumulate hazardous wastes in closed tanks or containers , and must complete a Uniform Hazardous Waste Manifest and use a registered hazardous waste transporter to transport the hazardous waste to either a permitted hazardous waste facility or to another location authorized to accept the waste . The disposal of hazardous waste is not allowed without a permit from DTSC . Hazardous waste generators who wish to conduct hazardous waste treatment on-site must first obtain a permit per CCR, Title 22, Section 66270 . 1 or HSC , Section ' 25189 . 5 . Note : Hazardous waste may not be disposed of to sewers , storm drains , surface waters , or to the land without a permit from DTSC and the Regional Water Quality Control Board . s A hazardous waste generator is defined in CCR, Title 22, Section 66261 .2 . c 4 I'
