Q. Wetlands. Those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally includes swamps, marshes, bogs, and similar areas.

3.7 What is the objective of CWA? The stated objective of the CWA is to restore and maintain the chemical, physical and biological integrity of the Nation's waters. The CWA provides regulations for discharges into surface waters from all types of sources (municipal and industrial point sources, and nonpoint sources). To achieve the stated objective, the CWA establishes as national goals:

(1) Achievement of a level of water quality that provides for the protection and propagation of fish, shellfish, and wildlife and for recreation in and on the water.

(2) Elimination of the discharges of pollutants into the navigable waters.

(3) Prohibition of the discharge of toxic pollutants in toxic amounts.

(4) Construction of Publicly Owned Waste Treatment Works (POTW) with financial assistance.

(5) Establishment of waste treatment management plans within each State.

(6) Establishment of technology necessary to eliminate the discharge of pollutants into the navigable waters, waters of the contiguous zone, and the oceans.

(7) Development and implementation of programs for the control of nonpoint sources of pollution.

3.8 Who implements the CWA? The CWA is a Federal/State program that prohibits discharges of any pollutants by any person except in compliance with the Act's permit requirements, effluent limitations, and other enumerated provisions. The State is often delegated authority to administer NPDES permits for discharges in the State. Additionally, many States have sewage treatment plant operator licensing and certification programs. Local entities may also have enforceable wastewater discharge limitations which regulate discharges to a POTW.

A. The CWA and all State-adopted water quality control laws require the States to establish and maintain water quality standards. A water quality standard is a numerical limit established for each parameter such as dissolved oxygen, pH, and turbidity, which is a suitable value for protecting the classified use of a particular water segment. A standard consists primarily of a numerical limit and may include a definition of how that limit is to be measured.

B. All point sources must treat their wastes to meet water quality standards in addition to applying technology-based effluent limitations. The water quality standards, in order to become effective for a particular point source, are translated into effluent limitations through permit conditions, which are issued to that point source. 

3.9 What is the National Pollution Discharge Elimination System (NPDES)?

A. Permit Requirements. The NPDES is a system of requirements to obtain permits for the commencement or continuation of any discharge of pollutants to surface waters. Discharge of pollutants without a permit is prohibited. The permit program gives the issuing authority precise information concerning the discharger's activities and provides advice to the discharger as to what is permissible. The NPDES permit establishes specific levels of performance the discharger must maintain and it requires the discharger to report failures to meet those levels to the appropriate regulatory agency.

(1) The effectiveness of the permit program in assuring compliance with applicable effluent limitations, water quality standards, pretreatment standards and other requirements depends on the effectiveness of monitoring and data maintenance requirements included in permits pursuant to Section 308 of the CWA for owner or operator of any point source.

(2) States have the opportunity to administer their own monitoring programs and upon obtaining EPA's approval of an appropriate monitoring program, the State becomes the monitoring authority for all point sources within its jurisdiction.

(3) The enforcing authority has the right to enter the premises of the discharger at any reasonable time, inspect the records, take test samples, etc.

(4) All data obtained under Section 308 of the CWA is required to be open to the public except to protect trade secrets.

(5) Results of monitoring must be reported as governed by the terms of the permit to the issuing authority on forms provided by the authority.

(6) Any discharge above the maximum daily discharge limitation for any of the pollutants listed in the permit must be reported within 24 hours as specified in the permit.

(7) NPDES permit application requires extensive waste stream analysis and cataloging of chemicals in the waste stream and imposition of controls on the discharge of these chemicals. All analytical testing must be done in accordance with State and/or EPA approved procedures pursuant to 40 CFR 136.3.

(8) NPDES permits may be valid for terms up to 5 years and may be subject to revocation or modification based on a very minimal showing of cause. Under EPA rules, the complete permit application must be filed at least 180 days prior to existing permit's expiration date. Earlier filing is strongly recommended for affected Service facilities.

(9) If a Service facility is discharging stormwaters associated with an industrial or construction activity, it is required to apply for an individual permit, apply for a permit through group application, or seek coverage under a general permit pursuant to 40 CFR 122.26(c).

B. Discharge of Toxic Pollutants. The discharge of most toxic pollutants is regulated under the Best Available Technology (BAT) effluent limitations guidelines, new source performance standards, and pretreatment standards pursuant to Section 307(a) of the CWA.

3.10 What is the policy regarding oil spills?

A. Spill Prevention. The CWA requires any facility that has the capacity to store oil products in an aboveground tank greater than 660 gallons, has a total aboveground storage capacity greater than 1320 gallons, or has an underground storage capacity of more than 42,000 gallons to maintain and implement an SPCC plan.

(1) All SPCC plans must be in accordance with 40 CFR 112.7 and must be reviewed and certified by a Registered Professional Engineer.

(2) Keep a complete copy of the SPCC plan on site and review it at least once every 3 years. Amendments are required whenever a change occurs that affects the facility's potential for discharge or to include more effective prevention and control technology.

(3) A copy of the SPCC plan must be available at sites that are normally attended at least 8 hours/day where there is a potential for a discharge.

(4) All facility personnel involved with the management and handling of oil and hazardous substances must take part in periodic training in spill prevention and response.

(5) All bulk storage tanks (over 660 gallons) must be provided with a secondary means of containment for the entire contents of the largest single tank plus sufficient free board to allow for precipitation.

(6) Appropriate containment and/or diversionary structures, and cleanup equipment to prevent discharged petroleum products from reaching navigable water course must be readily available at the facility.

(7) Drainage of rainwater from diked areas must be controlled by a valve that is locked when not in active use or attended.

B. Spill Notification. The CWA requires that the discharge of oil or a Reportable Quantity (RQ) of a hazardous pollutant into or upon the navigable waters of the United States or adjoining shorelines or into or upon the waters of the contiguous zone or into areas that may affect natural resources belonging to or under the exclusive management authority of the United States be brought to the attention of the National Response Center (NRC) at 800-424-8802. The Service facility manager/project leader must notify the Regional Spill Coordinator, whenever feasible, prior to notification to the NRC. Severe penalties apply to those who discharge oil or hazardous pollutant quantities in excess of the RQ and fail to report them and who fail to take appropriate cleanup and remedial action in response to such spills.

3.11 What is the Dredge and Fill Permit Program?

A. Section 404. Section 404 of the CWA controls dredging activity and the disposal of dredged or fill material into navigable water by granting the Corps of Engineers (COE) the authority to designate disposal areas and issue permits to discharge dredged and fill material therein. Section 404 authority extends to all waters of the United States, including wetlands, and the COE has construed it to cover the emplacement of dredge or fill material for development purposes and the construction of structures. Also, Section 404 permits are subject to the National Environmental Policy Act (NEPA).

B. Permit Program. States have been authorized to establish permit programs for dredge and fill activities in non-navigable waters. States must comply with extensive requirements and must obtain EPA's approval of the program. A copy of each permit application and each proposed permit also must be sent to the EPA, COE, and the Service for review and comments.

3.12 What is the Marine Sanitation Device Standard? The standard applies only to vessels that the United States owns and operates and on which a marine sanitation device has been installed.

A. Freshwater Sources. In freshwater lakes, freshwater reservoirs, or other freshwater impoundments, marine sanitation devices certified by the U.S. Coast Guard, installed on all vessels must be designed and operated to prevent the overboard discharge of sewage, treated or untreated, or any waste derived from sewage.

B. Other Waters. In all other waters, Coast Guard certified marine sanitation devices installed on all vessels must be designed and operated to either retain, dispose of, or discharge sewage. If the device has a discharge, the effluent must not have fecal coliform bacterial count of greater than 1,000 per 100 ml nor visible solids.

C. State Requirements. A State may completely prohibit the discharge from all vessels of any sewage, whether treated or not, into some or all of the waters within such State.
