REVISED MONITORING AND REP' -ING PROGRAM ORDER NO. R5-2008-r"c <br />HJ BAKER & BRO. INC., MARTIN 0, :ATING PARTNERSHIP, THE PORT 01 )CKTON, <br />AND METROPOLITAN STEVEDORE <br />MOLTEN SULFUR PROCESSING PLANTS <br />SAN JOAQUIN COUNTY <br />-3- <br />Baker's Facility—Specific Monitoring <br />Baker stockpiles its prill outside and exposed to the environment. When exposed to rain and/or <br />moisture, the stockpiles generate sulfur-contact water that drains across the floor of the <br />stockpile area and into a collection system. The collection system consists of lined sumps with <br />sump pumps, conveyance pipe, and a 500,000-gallon AST. Baker recycles its sulfur-contact <br />water through its pulling process. <br />This revised MRP requires that Baker monitor its sulfur-contact water at a location that is <br />representative of the sulfur-contact water generated by the prill stockpiles that are located 0 <br />the sulfur storage area (i.e., referred to by Baker as its "clay pit"). <br />Table 2 contains Baker's monitoring parameters and frequencies for sampling the sulfur-con <br />water. Baker must report its results twice per year according to the Reporting Due Dates <br />shown in Table A of Section A of this revised MRP. <br />Table 2 <br />Baker's Facility-Specific Monitoring of Its Sulfur Contact-Water <br />Field Parameters <br />Temperature <br />Specific Conductance <br />pH <br />Monitoring Parameters <br />Sulfur, total (EPA 200.7) <br />Total Dissolved Solids (EPA 160.1) <br />Sulfate (EPA 300 Series) <br />Major Anions (See Table 6) <br />Major Cations (See Table 6) <br />Units <br />°C <br />umhos/cm <br />SU <br />mg/L <br />mg/L <br />mg/L <br />mg/L <br />mg/L <br />Monitoring Frequency <br />January and July <br />January and July <br />January and July <br />January and July <br />January and July <br />January and July <br />January <br />January <br />ci
