Federally owned treatment works

Prior to discharge, the condensate flows to the on-site federally owned treatment works, which includes an activated-sludge sewage treatment plant. The crystallized salts are shipped to an off-site commercial treatment, storage, and disposal facility. 

The Effluent Filtration Module removes most of the remaining suspended solids from the SBR supernatant in the Continuous Backwash Sand Filter. The filter effluent is stored in the Filtered Effluent Surge Tank for transfer to the Federally Owned Treatment Works.

Finding 2-12a. The Army s plan to destroy highly organic neutralent waste streams by incineration is appropriate. Plasma arc systems are also adaptable to destruction of highly organic neutralents when incineration is not available or acceptable. Use of such high-temperature processes to destroy aqueous secondary wastes would be inefficient, although it may be expedient in some cases. If such aqueous liquids cannot be disposed via publicly or federally owned treatment works (POTW or EOTW), chemical oxidation or wet air oxidation may be attractive alternatives for this purpose. 

As was the case for RRS and MMD wastes covered in the earlier report, the treatment goals for the EDS neutralent destruction technologies considered are that the chemical species and their concentrations in the treatment residuals are such that the residuals could be released directly into the environment or to a pubUcly owned (or federally owned) treatment works (POTW or FOTW). Because this is a supplemental report, only the eight treatment technologies considered previously are considered here the same criteria used previously to evaluate these technologies are also applied here (see Appendix E).

Any residual agents, Schedule 2 compounds, or other materials in the neutralents are at low levels that do not preclude discharge directly to a POTW or federally owned treatment works (FOTW). 

Because acrylonitrile is listed as a hazardous substance, disposal of waste acrylonitrile is controlled by number of federal regulations (see Chapter 7). Rotary kiln, fluidized bed and liquid injection incineration are acceptable methods of acrylonitrile disposal (HSDB 1988). Underground injection is another disposal method. The most recent quantitative information on amount of acrylonitrile disposed in waste sites is for 1987. Emissions were 0.9 metric tons in surface water, 152 metric tons disposed through Publicly Owned Treatment Works (POTW), 92 metric tons disposed of on land 1,912 metric tons by underground injection (TR11988). Because acrylonitrile is relatively volatile and is also readily soluble in water, release to the environment from waste sites is of concern. 

The Federal Clean Water Act (CWA) mandates the establishment of pretreatment standards for discharges to "publicly owned treatment works" (POTW). Institutions that are connected to public sewers must comply with the CWA pretreatment standards. This could result in not allowing certain compounds down the drain even if diluted (e.g. formaldehyde cannot be discharged to a POTW even in minute quantities with abundant dilution). 

The Clean Water Act is an example of a federal law that is frequently delegated to the states for enforcement. Often the responsibility is passed down to the local level for setting water quality standards. The local authority, such as the publicly owned treatment works (POTW), then regulates industries that discharge their effluent to it.

Disposal in the sewer system (down the drain) had been a common method of waste disposal until recent years. However, environmental concerns, the viability of publicly owned treatment works (POTW), and a changing disposal culture have changed that custom markedly. In fact, many industrial and academic laboratory facilities have completely eliminated sewo" disposal. Again, like trash disposal, most sewo" disposal is controlled locally, and it is therefore advisable to consult with the POTW to determine what is allowed. Yet, it is often reasonable to consider disposal of some chemical waste materials in the sanitary sewer. These include substances that are water-soluble, that do not violate the federal prohibitions on disposal of waste materials that interfere with POTW operations or pose a hazard, and that are allowed by the local sewer facility. 

The committee began by establishing some boundaries for the study. As required by the Statement of Task, only liquid neutralent wastes from the RRS and MMD were considered. First, EDS neutralents were omitted because the liquid neutralent (at the time this report was developed) had not been well characterized. Second, the end point of the neutralent treatment technology was taken to be solids that could be disposed of in a permitted landfill and liquids that could be released to a federally owned or publicly owned treatment works. Third, the air discharges would contain only CO2, water vapor, and nitrogen. Therefore, setting discharge parameters would not be necessary. 

Waste from a municipal water system is normally treated in a publicly owned treatment works (POTW). In the United States, these systems are allowed to discharge only effluents that have attained a certain level of treatment, as mandated by federal law. One of the major objectives in the treatment of hazardous wastes, which usually have a high content of water, is to bring the water byproduct up to a quality that can be sent to a POTW for treatment and release.

Regardless of whether a state is authorized to implement either the NPDES or the pretreatment program, if it develops its own program, it may enforce requirements more stringent than federal standards. In any case, disposing to a POTW requires working closely with the treatment facility.
