Inspection found that facility did not use ATG correctly for release detection, nor did it provide any release detection for its pressurized piping. Field citation II-UST-FC-317EC was issued for violations of 40 CFR 280(a); failure to provide adequate release detection method and 40 CFR 280.41(b)(1(ii) failure to have annual line tightness tests or perform monthly monitoring on pressurized piping. ATG now used correctly and tightness tests on piping done.
