12VAC5-640-264. Operation and maintenance manual.
A. Prior to issuance of the operation permit, the owner shall submit an operation and maintenance (O&M) manual for the discharging system. The general purpose of the manual is to present both technical guidance and regulatory requirements to facilitate operation and maintenance of the discharging system for both normal conditions and generally anticipated adverse conditions. The manual shall be designed as a reference document, being as brief as possible while presenting the information in a readily accessible manner. The manual shall be tailored to the specific system. The manual must state the minimum required frequencies for routine maintenance, operation, sampling, and monitoring frequencies in this chapter, but additional maintenance visits, sampling, and monitoring may be added as needed, depending on the design of the system. The manual should reflect the minimum operation and maintenance activities required to properly maintain the system and ensure compliance with the General Permit requirements.
B. The manual shall include the following minimum items:
1. Basic information relevant to the discharging system design including treatment unit capacities, pump operating conditions, a list of the components comprising the discharging system, a dimensioned site drawing, sampling locations, and contact information for replacement parts and chemicals for each unit process;
2. Safety considerations;
3. A list of all control functions and how to use them;
4. All operation, maintenance, sampling, and inspection schedules for the discharging system including any requirements that exceed the minimum requirements of this chapter;
5. The General Permit effluent sampling and reporting schedule;
6. The sampling location for each of the required General Permit parameters and for informal (process control) testing parameters;
7. The expected ranges of any recommended informal (process control) tests;
8. The limits of the discharging system and how to operate the system within those design limits; and
9. Other information deemed necessary or appropriate by the designer.
