Section Env-Wq 707.05 - Basis of Design Report: Treatment Technology Options Considered

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.
