For each treatment technology option considered, the basis of design report shall include a description or analysis of:
- (a) The facilities associated with each proposed treatment technology option;
- (b) Design calculations and parameters used for sizing the unit processes and components for evaluation purposes to demonstrate compliance with all applicable federal and state design requirements;
(c) Environmental impacts, including:
- (1) Direct and indirect impacts on floodplains, wetlands, land resources, endangered species, and properties of historical and archeological significance;
- (2) Generation and management of residuals and wastes; and
- (3) Sprawl-related impacts;
(d) Sustainable utility management practice considerations, including:
(1) Water and energy efficiency, including:
- a. Water reuse and conservation;
b. Energy efficient design to reduce electrical demand and minimize carbon footprint, including:
- 1. Blower and pump sizing to provide energy-efficient operation at a full range of flow rates;
- 2. Use of premium efficiency motors;
- 3. Installation of heat recovery systems; and
- 4. Use of biogas capture and reuse if digesters are proposed;
- c. Renewable energy generation, if applicable to the treatment technology option; and
- d. Water and energy usage of each option as compared to other treatment technology options;
- (2) Aspects of project that preserve or mimic natural processes to manage onsite stormwater, if applicable to the treatment technology option; and
- (3) Site management of stormwater runoff volume and peak flows through infiltration, evapotranspiration, harvest, and use, if applicable;
- (e) Ultimate sludge disposal plans, including contingency plan as required by Env-Wq 716 for sludge stabilization, sludge thickening, and sludge dewatering; and
(f) Estimates of capital and operating costs for each treatment technology option, including:
- (1) Construction costs;
- (2) Total project costs;
- (3) Average annual operation and maintenance costs over the life of the project; and
- (4) Energy costs.
