Natural gas drilling can result in discharges to surface waters.

Sewage is treated to control water pollution before discharge to surface waters.

This includes emissions to air, discharges to surface waters, and on-site releases to land.

These actions resulted in significant reductions to the glycol discharges to surface waters.

Many industries treat biodegradable liquid wastes with bacteria before discharge to surface waters.

Depending on the results obtained, the effluent will either be infiltrated into the ground or discharged to surface waters.

The treated effluent may be suitable for discharge to surface waters or possibly for use on land.

All facilities reporting releases in 1996 also indicated use of secondary treatment systems prior to discharge to surface waters (Paper products sector, 1999).

The criteria are for surface waters; however, they may also apply to ground water where it is discharged to surface waters.

These sources include all industries, businesses, municipal sewage plants and storm sewer systems, and other facilities that discharge to surface waters.

MOEE (1994) Determination of treatment requirements for municipal and private sewage treatment works discharging to surface waters.

Industrial effluents contribute to about 1.3 BCM/yr of waste water being discharged to surface waters, only some of which is being treated.

The design recommendations presented will minimize the detrimental environmental effects of once-through cooling water systems, wastewaters discharged to surface waters and groundwaters, and solid waste disposal sites.

Surface water contamination also occurs as a result of direct runoff from waste sites to streams, lakes and wetlands, and indirectly as contaminated groundwater discharges to surface waters.

In the United States these standards are issued by the U.S. Environmental Protection Agency (EPA) for underground injection and discharges to surface waters.

The Scottish Executive Environment Protection Agency (SEPA) has a duty to control discharges to surface waters and groundwaters, including tidal waters out to the three-mile limit.

Total flows include effluent discharges, bypass event flows at the wastewater treatment plant and/or at pumping stations, combined sewer overflows and sanitary sewer system discharges to surface waters.

A Discharge Monitoring Report (DMR) is a United States regulatory term for a periodic water pollution report prepared by industries, municipalities and other facilities discharging to surface waters.

Do not add a new surface water body name unless it will be associated with at least one discharge to surface waters identified in field B12.3,otherwise the software will generate an "orphan water body"error.

A release is an on-site discharge of a pollutant to the environment, within the boundaries of the facility; this includes emissions to air, discharges to surface waters, on-site releases to land and deep-well underground injection.

In Canada, there exists a BOD5 (5 day) effluent guideline of 20 mg O2/L, which is a voluntary limit that applies to all existing or proposed land-based federal establishments discharging to surface waters (Environment Canada, 1976c).

The municipal P load discharged to surface waters (i.e., 5.6 thousand t/yr) is less than the household total because 63 to 93% of the P is removed at the MWTP, depending on the level of sewage treatment provided.

Economic Analyses of Control Documents on Private Sector Enterprises and Municipal Projects (GUIDELINE F-14) Effluent Disinfection Requirements for Sewage Works Discharging to Surface Waters (Procedure F5-4)

The EIS must also include an assessment of changes to coastal processes (e.g., shoreline morphology changes through erosion and sediment transport) with a particular focus on potential impacts of the increased flow from condenser cooling water or other discharges to surface waters and the proposed infilling of Lake Huron.
