NATIONAL TRAINING AND OPERATIONAL
TECHNOLOGY CENTER
The National Training and Operational Technology Center (NTOTC) is located
at the U.S. Environmental Protection Agency Environmental Research Center in
Cincinnati, Ohio.
NTOTC functions in conjunction with USEPA Regional Offices as the
operational focal point for the Office of Water Program Operations in course
development, course presentations, and assistance programs to help provide
Federal, State and local government agencies, educational institutions and the
private sector with the necessary training and skills required to achieve an
effective water pollution control and abatement program. Training self-
sufficiency at the State and local level is a major goal of NTOTC's efforts.
NTOTC conducts training courses in the areas of wastewater treatment, water
quality management, biology, and chemical and bacteriological analyses for
water quality control programs. Training manuals, audiovisual instructional
materials and instructor guides are prepared for use in the presentation of
courses.
NTOTC works directly with personnel at wastewater treatment facilities and
conducts on-site training in process control directed toward improving final
effluent quality. Based on extensive field experience in the operation of
-------
activated sludge treatment facilities, assistance and information for the
development of design criteria, new process control strategies, and training of
wastewater treatment personnel are provided.
NTOTC maintains a comprehensive Instructional Resources Center (IRC) to
provide assistance to those involved in pollution control training and education.
The purpose of the IRC is to systematically inventory and maintain current
pollution control training and education materials and to disseminate these
materials to governmental agencies, educational institutions and the private
sector.
The materials maintained by the IRC are listed in a comprehensive
computerized information base called the Instructional Resources Information
System (IRIS). IRIS categorizes each item according to several specific
parameters including the title, author, source and an abstract. This information
is available to assist in selecting materials for pollution control instructional
uses.
The IRC Study Lab, a special viewing room in the Environmental Research
Center in Cincinnati, is available Monday through Friday to permit educators to
review audiovisual instructional materials. NTOTC staff members are available
at the Center for consultation and assistance.
A major service of the IRC is the Lending Library. The purpose of this
component is to lend audiovisual instructional units to education and training
organizations to support classroom activities. Slide/tape units, videocassette
units and films are available for free, short-term loan. This Water Quality
Control Instructional Materials catalog has been prepared to inform water
quality control training personnel about supporting materials and services
available from the Lending Library.
Instructional materials available from the Lending Library fall into two
categories—audiovisual supportive materials and packaged courses. The
following pages of this catalog provide information on audiovisual materials
and packaged training courses that can be borrowed on a short-term basis from
the Lending Library. Audiovisual materials are designed to supplement
pollution control courses—they are not designed for independent learning. The
packaged courses include a complete unit of printed and audiovisual materials
to teach a specific pollution control topic or procedure.

SLIDE/TAPE INSTRUCTIONAL UNITS
The slide/tape instructional units listed on the following pages are currently used in support of
EPA training efforts. These training aids are not self-contained units designed to replace an
instructor, nor are they intended to provide an exhaustive coverage of any given topic; they
were developed to be used as part of an integrated water quality presentation.
Each unit consists of a set of 2" X 2" slides in sequential order in a carousel tray with cued
narration tape (ANSI Standard 1000 Hz) which automatically changes slides in a projector. To
activate automatic slide changes, the user will need a cassette player for standard size
cassettes to connect to a Kodak Carousel or equivalent to allow the electronic pulse to activate
the slide mechanism on the projector. For manual operation of the slide projector, all units
include a script of the narration with a clearly defined format indicating slide changes.
-------
SUGGESTIONS FOR THE DISCUSSION LEADER
PREPARATION:
-See the catalog description of the intended audience for the unit.
-Preview the instructional unit.
-Review the unit topic.
References are listed in the catalog. The script and any associated information are sent with
the unit. Questions about content should be directed to:
National Training & Operational Technology Center
Office of Water Program Operations
U.S. Environmental Protection Agency
Cincinnati, OH 45268
-Give viewers sufficient notice of any preparatory assignments.
UTILIZATION:
-Tell the viewers about the content of the program and important points to notice while
viewing. Tell them to concentrate on seeing and hearing rather than on taking notes during
the presentation.
-Run the program. The tape playback can be stopped during the program, if desired.
-Conduct a discussion of the content. Particular slides can be projected if desired.
-If necessary, run the program again.

LAND APPLICATION OF WASTES
An instructional package consisting of 21 lessons using printed matter and audiovisuals. The
course is designed for a workshop setting where participants are at all levels of experience.
Land treatment of municipal, agricultural and industrial wastes and residues as an efficient
means of pollution control and resource recovery is evaluated. Information for evaluation
derives from sanitary and environmental engineering, agronomy, soil science and agricultural
engineering, economics and law. The program provides a summary of the basic concepts that
make soil an effective treatment system. Design examples are used to develop problem
solving skills. The course uses an individualized modular approach.
The material in each module requires 0.5 to 3 hours of study time and describes the
knowledge needed prior to use, concepts to be presented, and knowledge to be presented,
and knowledge to be obtained. Concepts in the module relate to each other and to important
concepts in other modules.
The components of the program concentrate on the following topics:
Soil as a treatment medium
Site evaluation procedures
Design approaches
Social factors
Vegetative cover
Alternative treatment systems, efficiency and cost
Monitoring
Nitrogen management
- 73 -
-------
Phosphorus management
Toxic element interactions
Organics
Legal aspects
Crop selection
Non-crop uses
Costing procedure
Water management and climate effects
Completion of this course will enable participants to compare alternative cost estimates,
primary designs, and to locate potential land treatment sites for specific application.
Study materials include combinations of the following (1) a printed study guide, including
drawings, diagrams, questions and problems, (2) cassette audiotape to guide portions of the
module, (3) photographs, slides for viewing, models or mockups and (4) laboratory study
materials when appropriate. Basic needs required are study carrels, tutors, reference
materials and resource personnel. For further information, contact Mrs. Eileen Hopewell,
NTOTC.
