a --Efficient operations and maintenance saves money!

Since 1956-, nearly $20 billion has been spe--i7fhroukh/EPA's. Construction eants Progiat to build new waste-water treatment 'facilitieS or to Upgrade existing plants.If a.plant fails to do the job it's supposed to, or 1de-,teriorates, these tax monies are wasted'; There is Con-clusive-evidence that one-third to one-half of existingplants are not operating effectively and efficiently.

Undel the sponsorship of the Municipal 70peratiOPSBranch, tie Operation, ,Maintenance ,- and Management manualsdescribed on the following pages, were prepared by operationssperialists with years of in- plant- experience. The manualswere developed in cooperation with EPA regional techni.calstaff, as well as State and local governmental personnel.This Bibliography presents a summary description of -thedata included in the manuals. It will be noted that a t, ,broad spectrum of key information is overed, ranging fromdescriptions of -Process components' an, guidelines for plantstart-up, to troubleshooting, preventive maintenance andlaboratory testing procedures. Aerobic and Anaerobic SludgeDigestion alp addressed, and in Jude case ,histories of op-erational exeriences and probl m-solving techniques. Thematerials are` designed to asis the operators, plant owners,consulting engineers and educators.

Copies of the manuals may. be obtained by writing directto the U.S. Government Printing Office or the National Tech-nical InfoImation Service. Appropriate data for direct ordersare included as Appentlices I and V respectively.

questions relating to any of the -e documents should bedirected-to the appropriate EPA RegiO al Office. A listingof these mailing addresses is shown o _e inside back coverof this Bibliography.

A PLANNED MAINTENANCE MANAGEMENT STEM

FOR-MUNICIPAL WASTEWATER TREATMENT PLANTS

This information was developed and successfully_demonstrated as a Planned Maintenance Management Sys-tem (FMMS) at the lgmgd Lower Potomac WastewaterTreatment Plant of Fairfax County, Virginia. It out-lines a model maintenance management program for waste-water treatment plants throughout the United States. .

Specifics of maintenance needs on each' item ofplant equipment are provtded*and instructions on themaintenance of complex equipment are reduced-to simpleprocedures. For each procedure, the system includesdetails of themethods, materials, tools and petsonnelrequired; schedules the task, and provides for datarecording and feedback.

During the 12-month demonStration of the PMMS, asteady downward trend was noted in the frequency of mal-functions in various mechanical equipment. In many case's ,the early detection of danger signs led to positive cor-rective action in preventing breakdowns.

This report describes the system in technical de,tail; thoroughly explains the installation of the system,including acceptance by the mechanics and coordinationwith plant operations, and outlines an application of thesystem to other wastewater treatment facilities.

AFFECTS OF STATE7WIDEEMERGENCYRESPONSE PRObRAMS-.-

FOR MUNICIPAL WASTEWATER TREATMENT FACILITIES

The material - provided in- this document is designedto assist in the development of4State emergency programsin responding to spills of 'raw or inadequately treatedmunicipal wastewater. It emphasizes the legal aspectsof spill. reporting, the definition of .a reportable spilland State-wide aspects of- emergency response planning.

'Preliminary stepa in this work included a review ofexisting and proposed Federal statutes and current Statewater pollutio* control laws and regulations. Over 55State and inteistate agencies were asked to provide in-.information on existing or future water pollution contin-gency plans; over 200 wastewater treatment facility mana-gers provided'data on emergency actions.

Each State response plan must, of course, be adaptedto the local situation.

ESTIMATING LABORATORY NEEDS FOR

MUNICIPAL WASTEWATER TREATMENT FACILITIES

,Because treatment processes andof processes vary widely, laboratory needs must bespecifically tailored to each installation. Thismanual provides data to make posgible the roughestfmation of laboratory needs for municipste-water treatment plants., Criteria for physical fa-cilities, staffing _and laboratory aeryices are in-cluded.- Con'siderations-for sampling and testing:needs are presented for individual processes, and-include the minimum and the best testing require-ments. The testing programs are designed to meetthe needs of each process.

Guidelines for equipment an supplies are di-vided into six categories: Major Equipment;Xs-:cellaneous Equipment; Expendable Supplies, Glass andPlasticware Test Kits; and Chemicals. The guidelinesfor Major. Equipment and Chemicals. are based on test-ing requirements, while the others are usually general

, and indicate items needed at any laboratory.IIED

.

Estimates for-staffing needs are given as theannual base man-hours for laboratories serving theseveral types of treatment facilities, and includemethods for adjusting the number of man-hours forlocal conditions. The manual desc4bes two ways of

OPERATIONS MANUAL

PACKAGE.TREATMENT PLANTS

Padkage treatment plants were originally designed 'to serve areas not easily connected to existing sewagetreatment plants. Such areas.include the subdivisionsdeveloped the "fities" and commercial establishmentssuch as restaurants, motels and parks. recently,package plants have increased in size so they can servesmall municipalities Many were installed with the con-cept the plants would operate with aittle or noLoperatorattention. However, to meet today's more demandinglution discharge regulations, these plants do requiredaily attention by a knowedgeable and conscientious op-erator thoroughly familiar with the plant. 'Materials in-cludedkn this manual are designed to give the operatoran increased kn9wledge of the basic principles in theeffective operation of a package treatM4ht plant.

The document is also directed to the plant owner andthe design engineer. The owner may be either the actualpurchaser of the plant, if privately owned, or the indi-vidual(s) or group responsible for making policy decisionsconcerning the treatment plant, such as a city council.The owner is responsible for enlarging the treatment4plantwhen necessary, controlling sewer construction practXces inthe service area, keeping supplies at the plant and super-vising the operator. Most importantly, the owner, in thefinal analysis, is legally and administratively responsiblefor the performance of the treatment plant. Detailed des-criptions are provided, which outline the duties and re-sponlibilities of the owner.

Also, for the engineer, this manual provides informa-tion that can be used wholly or in part' with an O&M Manual,prepared for a si-,eific plant. It may be valuable to theconsulting engineer in pant selection, by alluding tovarious design problems inherent in previous package plantinstallations.
