This report is required by Sections (205)(a) and 5l6(b)(l) of the Clean Water Act. The 1988 Needs Survey, a joint effort by the States and EPA, assesses the capital investment required to build or improve needed municipal wastewater treatment facilities. The 1988 EPA estimates are limited to facilities that are eligible for construction grant funds, including categories eligible through the governors' discretionary authority under Section 201(g)(l) of the Clean Water Act. These estimates do not address the expanded eligibilities of the State Revolving Fund program established by the 1987 Amendments to the Act. The Report also highlights the current status of our Nation's municipal wastewater treatment infrastructure. In conducting the 1988 Needs Survey, we concentrated on maintaining national consistency in estimating and reporting needs by applying the same documentation criteria established in the 1986 Survey. Only facilities with acceptable documentation of water quality or public health problems are included in the EPA estimates. As in the 1986 Needs Survey, we encouraged all States to submit separate estimates where they believe additional needs exist that could not satisfy the water quality/public health based documentation criteria. I believe these efforts have continued to improve the quality of the Survey. I would be pleased to further discuss the results of this Survey at your convenience.

This report provides EPA's detailed estimate of the capital costs to build publicly owned municipal waste- water treatment facilities to comply with the requirements of the Clean Water Act. The 1988 Needs Survey focuses on construction grant eligible category of need, rather than the expanded State Revolving Fund eligi- bilities under the 1987 Amendments to the Clean Water Act. EPA's needs estimates include those facilities for which a water quality or public health problem could be docu- mented in accordance with specific criteria established in the 1986 Survey. The needs for documented facilities are: Ť $83.5 billion to satisfy all catego- ries of need for the design year (2008) population. Ť $67.9 billion to satisfy all catego- ries of need for the current (1988) population. The total design year needs for the Nation rose by $2.9 billion (4 percent) from 1986 to 1988. Compared to pre- vious Surveys, the overall change is small which suggests that grant- eligible needs are beginning to stabilize. The increase was due to a variety of factors. The major reason for the change is revised planning and design of facilities to address changes in project scope, including level of treatment, size of facilities, and greater focus on sludge treat- ment and disposal and new water quality-based permits. States submitted separate optional estimates for needs they believed to be authentic but did not meet the established documentation criteria. A total of 39 States and Territories submitted separate estimates for the 1988 Survey totaling $15.9 billion in design year needs. The 1988 Needs Survey identified a total of 10,835 facilities with docu- mented water quality or public health problems of which 6,248 are treat- ment facilities. A total of 15,591 treatment facilities are operating in 1988, and 17,374 facilities will be in operation when all documented needs are met. These operating facilities currently serve a population of 176 million, representing 71 percent of the Nation's population. When all needs are met, the population served will increase to 248 million or 87 percent of the Nation. Eighty-eight percent of existing treatment facilities currently provide secondary treatment or better. When design year needs are met, nearly all treatment facilities will provide secondary or better treatment. Currently, 13,802 facilities are provid- ing secondary or better levels of treat- ment (up 4 percent from 1986), 1,789 facilities with less than secondary treatment (down 12 percent from 1986), and 117 collection facilities with raw discharges (down 21 percent from 1986). Over 1,100 collection systems have combined sewer systems. Of these, 328 have documented needs in the 1988 Survey, totaling $16.4 billion to correct combined sewer overflow problems. In a separate assessment required by the 1987 Amendments of the Clean Water Act, EPA estimated the current wastewater treatment needs of Federally recognized Indian Tribes at approximately $270 million (in 1987 dollars) to serve over 400,000 Indians with identified needs. The assess- ment was conducted in cooperation with the Indian Health Service of the Department of Health and Human Services, and a report on Indian needs will be delivered to Congress under separate cover in early 1989. The 1987 Amendments authorized a special set- aside of approximately $30 million to fund wastewater treatment projects for Federally recognized Indian Tribes on reservations. A1988 Amendment extended set-aside eligibility to Tribes on former reservations in Oklahoma and Alaska Native Villages, as defined in P.L. 92 - 203. ------- ------- Introduction What is the Needs Survey? This report summarizes the Environ- mental Protection Agency's (EPA) biennial assessment of the cost of constructing all publicly owned wastewater treatment works necessary to meet the goals of the Clean Water Act. This report is required by Sections 205(a) and 516(b)(l) of the Clean Water Act. The 1988 Needs Survey, a joint effort of the States and EPA, is the ninth Needs Survey since enactment of the Federal Water Pollution Control Act Amendments of 1972. Cost estimates presented in previous Surveys have served as a basis for Congressional allotment of funds appropriated for the construction grants program in accordance with the provisions of the Clean Water Act. The Needs Survey is also used extensively to assist the Federal government and the States in pro- gram planning, policy evaluation, and program management. Private firms, public interest groups, and trade associations use Needs Survey information in marketing, cost estimating, and policy formulation. The Needs Survey data base contains cost and technical information on approximately 24,153 wastewater treatment and collection facilities nationwide, including facilities with unmet needs and those for which needs have already been met. The primary emphasis of this report is to summarize the cost information. Summaries of technical data are provided in Appendix C. More detailed technical tables will be published as an addendum to this report. ------- What is a "Need"? A "need" is a capital cost estimate for building a publicly owned waste- water treatment facility that may be eligible for Federal financial assis- tance under Title II of the Clean Water Act. Needs are estimated for facilities used in the conveyance, storage, treatment, recycling, and reclamation of municipal wastewater. Estimates are included for all types of required changes to wastewater facilities, such as the construction of entirely new facilities, and enlarging, upgrading, abandoning, and replac- ing existing facilities. Existing facilities are considered for replace- ment when they have reached the end of their design life and are no longer able to operate satisfactorily. Other types of changes to existing facilities are projected as a response to new statutory requirements of the Clean Water Act (1987 Amendments). Needs estimates do not include costs for operation and maintenance. They also do not include needs that are ineligible for Federal assistance under Title II of the Clean Water Act (1987 Amendments), such as house connections to sewers and certain land acquisition costs not part of a treatment process, nor do they include needs that are newly eligible under Title II or Title VI, such as stormwater, nonpoint source control, or estuary protection activities. The Needs Survey estimates are collected and reported by States in two ways. The first is by type of wastewater treatment project; the second is by timeframe. Type of Wastewater Treatment Project The types of wastewater treatment projects for which needs estimates are presented are: Category I - Secondary Treatment Category II - Advanced Treatment Category IIIA - Infiltration/Inflow Correction Category IIIB - Replacement/Rehabilitation of Sewers Category IVA - New Collector Sewers Category IVB - New Interceptor Sewers Category V - Combined Sewer Overflows Typically, costs for Categories IIIB (replacement/rehabilitation of sewers), IVA (new collector sewers), and V (combined sewer overflows) are ineligible for Federal financial assistance. However, costs for these categories are included because the Clean Water Act provides a governor with discretionary funding authority to use up to 20 percent of a State's construction grant allotment in any fiscal year for these project categories. Because there is no way of knowing which facilities will be funded, or how much of the 20-percent discre- tionary funding authority will be used in any State, the entire need is reported in the Survey. More detailed explanations of each cate- gory can be found in the Glossary of Terms. ------- Timeframe EPA estimates the capital investment necessary to address municipal wastewater treatment needs for two points in time: 1. Current Needs - needs for documented facilities to satisfy the current population on January 1,1988. 2. Design Year Needs- Total needs for documented facilities to satisfy the design year population. Year 2008 is used as the design year to better approximate a 20-year design life for facilities in the Needs Survey. Design year needs include current needs as a subset. In previous Surveys, we have also reported maximum eligible needs, i.e., the portion of the design year needs eligible for Federal financial assistance in accordance with Section 204(a)(5) reserve capacity limitations of the Clean Water Act. This provi- sion limits grant-eligible needs to that portion of a treatment works providing capacity to the existing population on the date of grant approval, or September 30,1990, whichever date is earlier. The 1987 Amendments provided for a transition from the traditional construction grant program to a State revolving loan program (SRF). Under the SRF Program, States will have the discretion to finance the construction of reserve capacity for future needs, therefore, the estimate of maximum eligible needs is no longer needed. ------- ------- The 1988 Needs Survey What Were The Major Objectives? The 1988 Needs Survey focused on grant-eligible categories of need, rather than the expanded eligibilities under the 1987 Amendments to the Clean Water Act. The major objective of the 1988 Survey was to update the 1986 cost estimates on all municipal wastewater treatment facilities. We applied the same documentation criteria established in the 1986 Needs Survey to ensure that a water quality or public health problem existed. These criteria were maintained to provide national consistency in estimating and reporting needs. We also encouraged States to update the technical data on wastewater treatment facilities such as flow, pollutant characteristics, treatment processes, and population estimates. Many of the States were successful in providing more current information. However, some States did not have resources to collect and report this information to EPA. ------- What Are the Needs? EPA's estimates of the capital invest- ment necessary to address the Nation's municipal wastewater treatment needs are presented in Table 1. An estimated $83.5 billion is required to satisfy the total needs of facilities with documented water quality or public health problems. Of this amount $67.9 billion is needed to satisfy the needs of the population in existence on January 1,1988 within the service area of these facilities. The $15.6 billion difference represents needs to serve population growth within these service areas between 1988 and 2008 (the design year population). If only Categories I, II, HIA, and IVB are considered, the design year needs are reduced to $49.6 billion and the corresponding needs for the current population drop to $36.9 billion. These categories include secondary and advanced treatment, infiltration/ inflow correction, and new interceptor sewers. The relationship of design year needs to current needs is shown in Figure 1.

To show how documented needs are distributed geographically through- out the Nation, we have disaggre- gated them by State. Figure 2 presents design year needs for Categories I through V, and shows that needs are generally concentrated in highly populated States such as Texas, Florida, New York, and California. Midwestern States are generally less populated, and consequently have lower needs. Figure 3 shows the needs for projected population growth (design year needs minus current needs). The distribution of States with the highest growth needs is similar to that shown in Figure 2, with the addition of Arizona, Tennessee, and North Carolina. Appendix A pro- vides a detailed presentation of needs for each State and U.S. Territory. Figure 2: Design Year Needs by State Range of Category I - V Needs (January 1988 Dollars in Billions) i r-, -. ,, Greater I $0.0-0.5 Q $0.5 -1.0 $1.0-2.0 D than $2.0 Figure 3: Needs for Projected Population Growth (1988 - 2008) by State Range of Category I - V Needs (January 1988 Dollars in Billions) $0.0 - 0.1 $0.1 - 0.2 $0.2-0.4 Greater than $0.4 ------- How Were the Needs Documented? The documentation criteria for the 1988 Needs Survey did not change from the 1986 Needs Survey. EPA re- viewed State-submitted documenta- tion for each facility and each cate- gory of need to ensure that the docu- mentation met the established list of criteria and was: based on a public health or water quality problem. A current problem (e.g., needs solely for future growth were unacceptable). Project specific (e.g., documenta- tion describing a county-wide problem of septic system failures due to poor soils was unacceptable to document the needs of a particular town in that county). States were also required to docu- ment their cost estimates in addition to their water quality or public health problems. The established documen- tation types were also used to verify cost estimates. The 17 EPA-approved documentation types for the 1988 Needs Survey are listed and defined in Appendix D. Once a State adequately documented a water quality or public health problem, EPA accepted it into the Needs Survey whether or not a documented cost estimate was available. For needs with undocu- mented or unavailable cost estimates, EPA used nationally derived cost curves to calculate the dollar amount.1 The curves used level of treatment (e.g., secondary or ad- vanced), general type of treatment (e.g., lagoon or mechanical plant), population, flow, and type of pro- posed improvement (e.g., upgrade, enlargement, abandonment, or recon- struction) to generate cost estimates. Some States maintain that not all their legitimate needs were included in the Survey because of the established documentation requirements. State concerns regarding documenta- tion are presented in the section entitled "What are the Separate State Estimates?" The most prevalent form of docu- mentation used to substantiate a water quality or public health prob- lem is a facilities plan. The resulting distribution of documentation types for facilities in the 1988 Needs Survey is depicted in Figure 4. Likewise, Appendix D illustrates that the majority of cost estimates are based on facilities plans and other planning documents.

After accounting for inflation, the total design year needs increased by $2.9 billion, approximately 4 percent, from 1986 to 1988. Estimates from the 1986 Survey are summarized by State in Appendix B. This net change since the 1986 Survey is due to several factors, primarily revised planning and design of facilities, which account for an increase of $4.6 billion. Such revisions resulted from changes to the scope of facilities, including level of treatment, size of facilities, and new requirements being imposed by State governments in response to the 1987 CWA Amend- ments. These new requirements address sludge treatment arid dis- posal, including toxics in sludge, and other new provisions of the CWA. Some States are also imposing more stringent effluent limits in new water quality-based permits. The second major reason for the change in needs is that some needs were met through grant awards between January 1986 and January 1988, accounting for a decrease of $3.6 billion. The third major reason for change between the 1986 and 1988 Surveys is recently identified needs for new wastewater treatment facilities, accounting for an increase of $1.9 billion. 11 ------- Needs have varied considerably from Survey to Survey. A comparison of the design year needs for the four most recent Surveys is presented in Table 2 and Figure 5. The most significant feature of this table is the S63.6 billion (43 percent) decrease in needs from 1982 to 1988. This de- crease is due to several factors includ- ing the emphasis on documentation requirements which began with CSO (Category V) needs in the 1984 Survey and was extended in 1986 to all cate- gories of need. Table 2 shows that the needs categories with the largest dollar changes are combined sewer overflows (Category V), sewer replacement/rehabilitation (Category UIB), and new collector sewers (Cate- gory IVA). Combined sewer overflow needs increased by $0.7 billion, accounting for 24 percent of the increase from 1986 to 1988, and sewer replacement/rehabilitation and new collector needs increased by $0.6 billion (21 percent of the increase) each. Betxveen 1986 and 1988, the total number of existing treatment and collection facilities increased by about 185 to 24,153 hi the 1988 Survey. Of the total 24,153 treatment and collection facilities included in the 1988 Survey, 10,835 have remaining needs. This represents an increase of 7 percent from the number of facilities with needs in the 1986 Survey.

The 1982 and 1984 Surveys estimated design year needs for the year 2000 population. The 1986 Survey estimated needs for the year 2005 population, and the 1988 Survey estimates needs for the year 2008 population to better approximate a 20- year design life for the facilities in the Survey. For comparison purposes, all the needs have been presented in January 1988 dollars. EPA has also included total needs in nominal dollars (the face dollar value not adjusted for inflation) so that these numbers can be compared to past Survey reports. A modification to the published needs estimates in the 1986 Survey has been made to account for an inflation adjustment.

Needs documented in accordance with the 17 criteria discussed in the section entitled "How Were the Needs Documented?" and described in detail in Appendix D are included in the EPA estimates in Tables 1 and 2. Needs that could not be docu- mented with any of the 17 accepted criteria but which States believe are valid needs are included in the separate State estimates in Table 3. States had the option, if available resources permitted, to submit separate State estimates for needs with documentation outside the 17 established criteria or without written documentation. The level of effort by each State varied as separate State estimates were voluntary, not mandatory. The reported needs are not all inclusive or representative of the total needs that would be reported as separate State estimates if State resources allowed. The types of needs identified by the individual States are too varied to allow com- parisons or conclusions on a national basis. A total of 39 States and Territories submitted separate State estimates compared to only 12 in 1986. The design year separate State estimates total $15.9 billion, an increase of $456 million (3 percent) from 1986 to 1988. The separate State estimates are in addition to the EPA estimates. If these estimates are added to the EPA assessment, the total design year needs for 1988 would be $99.4 billion, or 19 percent more than the EPA estimate. A detailed listing of the current and design year separate State estimates are included in Appendix A. ; Table 3 Separate State Estimates - Current and Design Year Needs Alabama Arizona Arkansas California Connecticut Florida Georgia Illinois Indiana Kansas Kentucky Louisiana Maine Maryland Michigan Mississippi Missouri Montana Nevada New Hampshire New, Jersey Current 12 ' 112 228 ; 759 [ 175 ; 19 ' 11 : 792 ! 10 0 8 i 78 ; 863 57 , 0* , 114 ; 64 : 2 ' 12 55 , 7 (Dollars Design 13 210 312 2003 177 39 14 792 260 0* 31 104 872 60 0* 167 80 15 18 11 7 in Millions) Year New Mexico New York North Carolina Oregon Pennsylvania Rhode Island South Carolina South Dakota Texas Utah Virginia Washington West Virginia Wisconsin Wyoming Guam Marshall Islands Puerto Rico Total Current 108 6310 7 275 1757 46 69 1 4 377 423 75 127 36 18 0 9 258 13278 Design Year 111 6316 10 541 1852 46 1-12 1 11 566 424 142 139 46 18 1 9 327 15857 * Estimate less than $0.5 million . In general, the States reported the following types of additional needs: Needs to build or expand a central- ized system for communities on individual systems. Specific plans or studies (in accordance with the 17 criteria) describing a current problem often do not exist. Also, many communities on septic systems may not have an existing problem, but States believe these systems will fail in the future due to differentiation in lot sraes, or soil or hydrological conditions. Needs to address combined sewer overflow problems where no formal study is available to document evidence of a public health or water quality problem. Needs that are strictly for future growth without any current public health or water quality problems. Although they may become docu- mented needs in the future, they were systematically excluded from the Survey because of the emphasis on current problems. Needs for facilities that are now operating at a satisfactory level, but which are projected to need replacement during the next 20 years and presently have no planning documentation. Other needs (e.g., needs ineligible for construction grant funding, needs using different estimation procedures, or needs not covered by the aforementioned reasons). 13 ------- What is the Status of Municipal Wastewater Treatment Infrastructure? The Federal investment in construc- tion grants, combined with State and local matching funds, has yielded significant infrastructure improvements in our municipal wastevvater treatment capabilities. In the last 10 years, the number of secondary and advanced treatment facilities has steadily increased. Municipalities currently operate over 24,000 treatment and collection facilities, of which 15,591 provide treatment. Presently, 13,802 or approximately 90 percent of all treat- ment facilities are providing at least secondary treatment. However, 117 remaining collection facilities discharge raw sewage. Figure 6 char- acterizes the current treatment capabilities for all operating domestic wastewater facilities. A total of $49.6 billion is needed to meet design year needs in Categories I, II, HIA, and IVB. The infrastructure improvements from meeting these needs are summarized in Table 4.

Most combined sewer systems have the capacity to handle both stormwater and wastewater flow; however, during larger storm events, the flow capacity of these sewer systems may be exceeded. Often the excess flow containing raw sewage, industrial wastewater, and stormwater is discharged un- treated. Current documented needs to control and treat CSOs total $16.4 billion for 328 CSO systems. These CSO systems, with documented needs in the 1988 Survey, serve approximately 25 million people. Over half of the documented national CSO needs are for 53 marine and estuarine CSO systems serving approximately 12 million people. 15 ------- ------- Impacts of the 1987 Amendments to the Clean Water Act A total of $50.6 billion has been obligated through the construction grant program as of September 30, 1988. Construction grants have been awarded primarily for the needs of municipal wastewater treatment facilities. This includes limited funding of related facilities such as combined sewer overflow correction under the Governor's 20 percent dis- cretionary fund in the construction grants program. The governor's discretionary fund was broadened in the 1987 Amendments to allow funding of nonpoint source and groundwater activities. The 1987 Amendments also intro- duced a major change in the financing of municipal wastewater treatment facilities. Federal financial assistance will be through the State Revolving Fund (SRF) in which municipalities may apply for a low- interest rate loan or other assistance rather than a traditional construction grant. The SRF program gives the States more flexibility in the types of projects which can receive Jfunding, including estuarine, nonpoint source, and combined sewer overflow projects. After certain requirements are met, States can allocate SRF funding to a broader range of projects, addressing prob- lems that they consider most signifi- cant in terms of achieving their water quality goals. In the Amendments, Congress authorized $18 billion for water pollution control through fiscal year (FY) 1994, $9.6 billion for the exist- ing construction grant program through FY 1990, and $8.4 billion in "seed" money to capitalize the SRF program through FY 1994. Under the 1987 Amendments, there are new enforceable requirements for storm- water, toxics, and sludge problems, which will have to be addressed once EPA completes development of the regulations. The status and impacts of the SRF program will be addressed in the SRF Report to Congress due in 1990 under Section 516(g) of the Clean Water Act. The 1988 Needs Survey will serve as the basis for estimating needs of noncompliant facilities in the SRF Report to Con- gress. In addition to preliminary projections of the SRF program, the report will provide a construction grant baseline against which future SRF data can be compared. 17 ------- ------- Glossary NOTE: Definitions are given to help the reader understand the terms used, but are not to be used for legal purposes. 19 ------- ------- Glossary Advanced Treatment See Needs Categories, Category II. Biochemical Oxygen Demand (BOD) The amount of dissolved oxygen required to decompose organic matter in water. BOD is a measure of pollution since heavy wasteloads have a high demand for oxygen. Collector Sewers See Needs Categories, Category IVA. Combined Sewer Overflows (CSO) See Needs Categories, Category V. Conveyance Needs Capital investment needed to construct, expand, or upgrade sewer systems for transporting wastewater to treatment plants. Conventional Pollutants Pollutants consisting of orgcinic wastes such as biochemical oxygen demand (BOD) and suspended solids (SS). Domestic sewage and industrial wastes of plant and animal origin contribute to the formation of these conventional pollutants. Current Needs The cost estimate for building publicly owned wastewater treatment facilities (to serve the 1988 population) eligible for Federal financial assistance under the Clean Water Act. Design Capacity The average daily flow that a treatment plant is designed to accommodate. Design Year Needs The cost estimate for building publicly owned wastewater treatment facilities to satisfy the design year (2008) population for documented facilities. The design year estimate also includes current year needs as a subset. Do cumentation A process in which the States were required to provide certain plans, reports, etc. to show that an actual problem existed and that it was: (1) related to a water quality or public health problem, (2) current, and (3) project specific. Needs were documented by using the list of 17 documentation types which the EPA accepted as verification of a need and a cost estimate. This list of 17 docu- mentation types is listed in Appendix D. Effluent Liquid that is discharged to the environment from a treatment facility after completion of the treatment process. Effluent Standard A limit on how much of a particular pollutant may be discharged by industries and municipalities into the environment. Effluent standards are set for each individual treatment facility. Minimum standards for all plants are set by ti.<; Clean Water Act. More stringent standards are set on a case-by-case basis when- ever the protection of local water quality warrants. 21 ------- Glossary Enforceable Requirements Conditions or limitations under Clean Water Act Section 402 or 404 permits which, if violated, could result in the issuance of a compliance order or initia- tion of a civil or criminal action under Section 309 of the Act or applicable State laws. If a permit has not been issued, the term includes any requirement which, in the Regional Administrator's judgement, would be included in the permit when issued. Where no permit applies, the term includes any require- ment which the Regional Administrator determines is necessary for the best practicable waste treatment technology to meet applicable criteria. Facilities Plans Plans and studies which directly relate to the construction of treatment works necessary to comply with the Clean Water Act. A facilities plan investigates needs and provides information on the cost effectiveness of alternatives. A recommended plan and an environmental assessment of the recommendations are also presented in a facilities plan. A facilities plan includes a description of the treatment works for which construction drawings and specifications are to be prepared. The description includes preliminary engineering data, cost estimates for design and construc- tion of the treatment works, and a schedule for completion of design and construction. Infiltration/Inflow Correction See Needs Categories, Category IIIA. Influent Wastewater flowing into a treatment facility. Interceptor Sewers See Needs Categories, Category IVB. Lagoon A pond in which algae, sunlight, and oxygen interact to restore water to a quality that is often equal to the effluent from the secondary treatment stage. Lagoons are widely used by small communities to provide wastewater treatment. Majors Publicly owned treatment works (POTWs) with flows greater than or equal to 1 million gallons per day (mgd) or service population equivalent to 10,000 persons and certain other POTWs having significant water quality impacts. National Estuary Program A program established under the CWA Amendments of 1987 to develop and implement conservation and management plans for protecting estuaries. Objectives include restoring and maintaining the chemical, physical, and bio- logical integrity of the estuary as well as controlling point and nonpoint pollution sources. Minors Publicly owned treatment works (POTWs) with flows less than 1 million gallons per day (mgd). 22 ------- Glossary National Municipal Policy (NMP) A policy created by EPA and the States in 1984 to bring all POTWs into compli- ance with Clean Water Act requirements. The deadline for compliance was July 1,1988 and it applied regardless of whether a facility had received any Federal funding. The NMP applied to facilities that needed construction as well as facilities that needed to improve operation and maintenance to comply. Needs The cost estimate for constructing publicly owned wastewater treatment facilities potentially eligible for Federal financial assistance under the Clean Water Act. Needs Categories Categories of projects that are potentially eligible for Federal financial assistance under the Clean Water Act. Needs categories are as follows: 1) Secondary Treatment (Category I) The minimum level of treatment that must be maintained by all treatment facilities, except those facilities granted ocean discharge waivers under Sec- tion 301 (h) of the Clean Water Act. Treatment levels are specified in terms of the concentration of conventional pollutants in the wastewater being dis- charged from a facility. Secondary treatment requires an 85-percent reduc- tion in conventional pollutant concentration in the wastewater treated by a facility. Needs reported in this category are necessary to attain secondary treatment. Needs to attain incremental reductions in conventional pollutant concentrations beyond secondary treatment requirements are included in Category II. 2) Advanced Treatment (Category II) A level of treatment more stringent than secondary treatment. Advanced treatment requires greater than 85 percent reduction in conventional pollutants, or a significant reduction in nonconventional pollutants present in the wastewater treated by a facility. Needs reported in this category are necessary to attain incremental reductions in pollutant concentrations beyond basic secondary treatment. 3) Infiltration/Inflow Correction (Category IIIA) Control of the problem of penetration into a sewer system of water other than wastewater from the ground through such means as defective pipes or manholes (infiltration) or from sources such as drains, storm sewers, and other improper entries into the system (inflow). Included in this category are costs for correction of sewer system infiltration/inflow problems. Costs also are reported for preliminary sewer system analysis and for detailed sewer system evaluation surveys. 4) Replacement/Rehabilitation of Sewers (Category IIIB) Reinforcement or reconstruction of structurally deteriorating sewers. This category includes cost estimates for rehabilitation of existing sewer systems beyond those for normal maintenance. Costs are reported if the corrective actions are necessary to maintain the structural integrity of the system. 5) Collector Sewers (Category IVA) Pipes used to collect and carry wastewater from an individual source to an interceptor sewer that will, convey the wastewater to a treatment facility. This category includes the costs of constructing new collector sewer systems and appurtenances. 23 ------- Glossary 6) Interceptor Sewers (Category IVB) Major sewer lines receiving wastewater flows from collector sewers. The interceptor sewer carries wastewater directly to the treatment plant or to another interceptor. This category includes costs for constructing new interceptor sewers and pumping stations necessary for conveying wastewa- ter from collector sewer systems to treatment facilities or to another interceptor. 7) Combined Sewer Overflows (CSO) (Category V) A discharge of a mixture of stormwater and domestic wastes that occurs when the flow capacity of a sewer system is exceeded during a rainstorm. Costs reported are for grant-eligible facilities to prevent or control periodic bypassing of untreated wastes from sewers which convey a combination of wastewater and stormwater to achieve water quality objectives. This cate- gory does not include costs for overflow control allocable to flood control or drainage improvement, or for treatment or control of stormwater in separate storm and drainage systems. Nonconventional Pollutants Pollutants other than the traditional TSS and BOD such as nitrogen, phosphorus, or ammonia which may be in the form of organic wastes, sediments, viruses, bacteria, oil, grease, acids or heat. Nondischarging Treatment Plants A nondischarging treatment plant is one in which treated wastewater is not dis- charged to any stream or river. Most of these nondischarging plants are pond systems that dispose of the total flow they receive by means of evaporation or percolation to groundwater, or facilities that dispose of their effluent by recy- cling, reuse (e.g., spray irrigation or groundwater recharge). Ocean Discharge Waiver A variance from the secondary treatment requirements for discharges into marine waters under Section 301 (h) of the Clean Water Act. Primary Treatment The first stage of wastewater treatment; removal of floating debris and solids by screening and sedimentation. Replacement/Rehabilitation of Sewers See Needs Categories, Category IIIB. Reserve Capacity Extra treatment capacity built into treatment plants and interceptor sewers to accommodate flow increases due to future population growth. Secondary Treatment See Needs Categories, Category I. Separate State Estimates Needs which were not included in the EPA estimates presented in this report because these needs either were justified with documents outside the estab- lished documentation criteria or had no written documentation. Septic Tank Used as part of an on-site septic system to treat and dispose of wastewater from an individual house. The septic tank is the predominant method used to treat 24 ------- Glossary wastewater from individual houses located in unsewered areas. The septic tank is an enclosure that stores and processes wastes. Bacteria decompose the organic matter into sludge which must be pumped off periodically. The liquid is disposed of through a subsurface drain field. State Revolving Fund Revolving funds are financial institutions that make loans for specific water pollution control purposes and use loan repayments, including interest, to make new loans for additional water pollution control activities. Under the State Revolving Fund (SRF) program, States and Municipalities will be primarily responsible for financing, constructing, and managing wastewater treatment facilities. The SRF program is based on the 1987 Amendments to the Clean Water Act which called for a phase-out of the construction grants pro- gram and the initiation of the SRF program. Suspended Solids (SS) That portion of the pollutants that are in the form of very small solid particles. Suspended solids are removed through a combination of settling and filtering operations. Tertiary Treatment Advanced treatment of wastewater that goes beyond the secondary or biologi- cal stage. It removes nutrients such as phosphorus and nitrogen. See Needs Categories, Advanced Treatment, Category II. 301(h) Ocean Discharge Waiver A variance from the secondary treatment requirements for treatment facilities discharging to bays or estuaries. Treatment Plant A structure constructed to treat wastewater prior to discharging to the environ- ment. Treatment is accomplished by subjecting the wastewater to a combina- tion of physical, chemical, arid/or biological processes which reduce the con- centration of contaminants in the wastewater. Trickling Filter Unit Process A biological treatment process where wastewater is treated by trickling waste- water over rocks or other media on which colonies of bacteria are growing. The bacteria remove the organic impurities from the wastewater and use it as a food source. The name "trickling filter" is a misnomer since no filtering action occurs in a physical sense. Water Quality-Based Permit A permit with an effluent limit more stringent than a limitation based on technology performance. This more stringent limit may be necessary to protect the designated use of a receiving water body (i.e., recreation, irrigation, indus- try, or water supply use). An effluent limit is a restriction on the amount of a specific pollutant that a facility can discharge into a stream, river, or harbor. Wastewater Dissolved or suspended waterborne waste material. Sanitary or domestic wastewater refers to liquid material collected from residences, offices, and institutions. Municipal wastewater is a general term applied to any liquid treated in a municipal treatment plant. Industrial wastes refer to wastewater from manufacturing plants. 25 ------- Glossary Wastewater Infrastructure The plan or network for the collection, treatment, and disposal of sewage in a community. The level of treatment will depend on the size of the community, the type of discharge, and/or the designated use of the receiving water. 26 ------- ------- ------- Appendices These Appendices contain State and national summaries of various cost and technical data.

The current needs represent the capital investment necessary to build all needed publicly owned wastewater treatment facilities to meet the requirements of the Clean Water Act. The current needs do not contain an allowance for future population growth and migration. The assessment includes all planning, design, and construction activities eligible for Federal financial assistance under the Clean Water Act. All ineligible project costs are excluded from the assessment. States were asked to provide both design year and current needs for all facilities in the 1988 Survey. For facilities where the current needs were unavailable, the EPA estimated them by prorating needs based on the ratio of 1988 to 2008 popu- lations. Needs estimates presented in Table A-1 may vary slightly from those presented in Table 1 due to rounding.

A-3 ------- Table A-2 1988 Needs Survey Design Year Needs for Publicly Owned Wastewater Treatment Works Table A-2 summarizes the 1988 EPA assessment of documented needs by State to satisfy the design year (2008) population. The total design year needs represent the capital investment necessary to build all publicly owned wastewater treatment facilities that have met the established documentation criteria. These are the funds necessary to provide adequate wastewater treatment systems for the 1988 population, plus population growth and migration for the next 20 years.
