2.4.2.2
Peak Flows. Peak flows will normally be higher during
a specific 8-hour shift during the day (or during a specific day
at single shift shops). The peak flow shift should be utilized
as the basis for sizing treatment facilities.
2.4.3
Flow Characteristics
2.4.3.1
Monitoring. Determine industrial wastewater
characteristics for design from a survey of the actual wastes
involved or from knowledge of waste at similar facilities.
Refer to the Environmental Protection Agency's (EPA) PB 259146,
Handbook for Monitoring Industrial Wastewater for sampling and
gaging techniques. Use of waste parameters from similar
facilities is practical where monitoring of actual wastes may be
difficult or costly; however, monitoring major flow
contributions at a specific facility is the preferred method.
Ensure that waste monitoring and characterization programs are
adequate for full development of design criteria.
2.4.3.2
Typical Characteristics. Characteristics of
discharges from some industries commonly associated with Navy
facilities are presented in Table 2. These characteristics are
only for preliminary engineering analysis. Characteristics of
wastes from other industrial processes at Navy facilities may be
found in the technical literature. Daily and process-related
variations in wastewater characteristics should be identified
and related to production operations to facilitate development
of control strategies.
2.4.3.3
Discharge Criteria. Identify effluent criteria
applicable to discharge from proposed industrial waste treatment
plant for either NPDES permit or local pretreatment requirements
or recycling to another process. Refer to paragraph 2.2.3.
Metal finishing and battery manufacturing (motor pool)
are the only categorical industrial waste types listed in Table
2 that have final pretreatment and direct discharge limits
established by EPA pretreatment standards. Refer to Title 40
CFR, Part 403, for metal finishing regulations and Title 40 CFR,
Part 403, for battery wastes. None of the other listed waste
types have established categorical standards. Consult local,
state, and Federal regulatory agencies to determine applicable
discharge standards for these waste types.
