GENERAL PURPOSE

Under general supervision (Source Control Inspector I) to direction (Source Control Inspector II), inspects pretreatment processes to ensure users are in compliance with mandated requirements; inspects customer facilities to ensure compliance with District ordinances and regulations regarding the use of reclaimed water; develops, implements and maintains Source Control program documentation and databases; when assigned to plan check, receives and reviews new Commercial Waste Discharge Applications and assesses for pre-treatment requirements and issues, and reads and interprets drawings and specifications for compliance with standards, rules and regulations; and performs related duties as assigned.

DISTINGUISHING CHARACTERISTICS

Source Control Inspector I: This is the entry-level classification in the Source Control Inspector series. Initially under close supervision, incumbents learn and perform routine inspection processes in conjunction with the District’s Environmental Compliance Source Control programs. As experience is gained, assignments become more varied, complex, and difficult; close supervision and frequent review of work lessen as an incumbent demonstrates skill to perform the work independently. Positions at this level usually perform most of the duties required of the positions at the Source Control Inspector II level but are not expected to function at the same skill level and usually exercise less independent discretion and judgment in matters related to work procedures and methods. Work is usually supervised while in progress and fits an established structure or pattern. Exceptions or changes in procedures are explained in detail as they arise.

Source Control Inspector II: This is the fully qualified journey-level classification in the Source Control Inspector series. Positions at this level are distinguished from the Source Control Inspector I by the performance of the full range of duties as assigned, working independently, and exercising judgment and initiative. Positions at this level receive only occasional instruction or assistance as new or unusual situations arise and are fully aware of the operating procedures and policies of the work unit.

This class is distinguished from the Senior Source Control Inspector in that the latter performs the more complex work assigned to the series and/or provides technical and functional direction over lower level staff.
