- (a) Sludge stabilization processes shall be designed to meet the requirements of Env-Wq 800 for pathogen and vector attraction reduction for Class A or Class B biosolids.
- (b) Proprietary processes for which design criteria are primarily provided by equipment manufacturers to accommodate their equipment and design concepts shall be supported by a detailed basis of design which cites existing successfully-operating facilities with similar solids types and similar capacities with similar design criteria.
- (c) Access for maintenance, repair, and inspection shall be provided for all stabilization process equipment and related tankage.
(d) Safety devices shall include:
- (1) Automatic shutdown upon critical system component malfunction;
- (2) Alarm systems for equipment failure; and
- (3) Alarm systems for hazardous conditions.
- (e) Redundancy of equipment and tankage or storage shall be provided so that the solids stabilization process will continue to be operable in the event of a failure of any single system component.
- (f) Odor control technology and practices shall be provided to control odors generated from the solids handling processes to minimize the impact of odors outside the facility property boundaries.
- (g) A written contingency plan that describes how solids processing and sludge removal will continue in the event of stabilization process equipment failure shall be submitted to the department pursuant to Env-Wq 703 for all proposed stabilization processes.
