system. The installation environmental engineer is usually the individual responsible for
determining when pretreatment is required and which methods will be used.
Water Discharge Restrictions. The discharge of industrial water
treatment system wastes may be regulated. All requirements can be established by
working with the installation environmental engineer. The primary restriction is water
quality. In addition to water quality restrictions, the discharge may be controlled in the
Discharge Location. The location of the discharge can be determined by
the configuration of both the water treatment system and the available sewers. Normal
practice at the installation may include discharge into either the sanitary or industrial
wastewater treatment system.
Discharge Rate. The maximum rate of discharge to the designated sewer
system may be a discharge requirement. Two factors are of importance in setting a
maximum rate: the hydraulic capacity of the sewer and the strength (chemical
concentration) of the waste.
Discharge Time. Discharge from a water treatment system unit may be
allowed only at specified times.
Discharge Responsibilities. The water treatment system operator is
responsible for complying with the procedures and policies established at the
installation, including directives on waste disposal that have been issued by the
installation environmental engineer. The responsibilities of the installation environmental
engineer include compliance of the installation's directives with government
Review of Chemicals. The installation environmental engineer should
review the procedures for use of a new water treatment chemical to determine whether
or not it can be safely disposed of using the existing procedures, or if new disposal
procedures must be developed.
Environmental Regulations. Numerous environmental regulations
established by law may apply at the installation level. Current regulatory information is
available from the installation environmental engineer.
The Toxic Substances Control Act. The Toxic Substances Control Act
(TCSA) authorizes the United States Environmental Protection Agency (EPA) to control
all new and existing chemical substances that have been determined to pose a potential
unreasonable risk to the public health or environment.
The Clean Water Act. The Clean Water Act (CWA) incorporates the
Federal Water Pollution Control Act and amendments. The CWA establishes limits for
the discharge of pollutants to navigable waters, provides regulation of specific toxic
