Current through Register Vol. 40, No. 24, July 15, 2024
A. The permittee
				  shall develop and submit to the department an operations and maintenance manual
				  in accordance with
				  9VAC25-740-120
				  B 3 f for each reclamation system, SRS, or combination of these facilities

				  changes in the practices and procedures followed by the permittee shall be
				  documented and submitted to the department within 90 days of the effective date
				  of the changes.
B. For each
				  reclaimed water distribution system, the permittee shall develop an operations
				  and maintenance manual to be made available at a location central to the
				  system. The permittee shall maintain the manual and include any changes in the
				  practices and procedures followed by the permittee in the manual. The
				  operations and maintenance manual for a reclaimed water distribution system may
				  be included in the operations and maintenance manual described in subsection A

D. The operations and maintenance manual is a
				  set of detailed instructions developed to facilitate the operator's
				  understanding of operational constraints and maintenance requirements for the
				  reclamation system, SRS, or reclaimed water distribution system; and the
				  monitoring and reporting requirements specified in the permit issued for each
				  system. The scope and content of the manual will be determined by the
				  complexity of the system or systems described by the manual.
1. For a reclamation system or SRS, the
				  operations and maintenance manual shall, at a minimum, contain the following:
a. A description of unit treatment processes
				  within the reclamation system or SRS and step-by-step instructions for the
				  operation of these processes;
b.

				  works;
h. Information necessary for
				  the proper management of sludge or residuals from reclamation treatment that is

				  coordinate with the education and notification program specified in
				  9VAC25-740-170
				  A for any release of untreated or inadequately treated water to the reclaimed
				  water distribution system.
