Comments— (include information on repairs made prior to testing, and recommended follow-up for jailed tests) Maintance repairs were preformed to all 3 Turbin sumps and disp7/8 Entero boots for product /vapor and electrical were resealed to sump walls Test was ran with water 2" above highest oenatration with passing results ' If the entire depth of the sump is not tested, specify how much was tested. If the answer to any of the questions indicated with an asterisk(*)is"NO"or"NA",the entire sump must be tested. (See SWRCB LG-160)
