Sec. 403.20  Pretreatment Program Reinvention Pilot Projects Under Project XL.

    The Approval Authority may allow any publicly owned treatment works 
(POTW) that has a final ``Project XL'' agreement to implement a 
Pretreatment Program that includes legal authorities and requirements 
that are different than the administrative requirements otherwise 
applicable under this part. The POTW must submit any such alternative 
requirements as a substantial program modification in accordance with 
the procedures outlined in Sec. 403.18. The approved modified program 
must be incorporated as an enforceable part of the POTW's NPDES permit. 
The Approval Authority must include a reopener clause in the POTW's 
NPDES permit that directs the POTW to discontinue implementing the 
approved alternative requirements and resume implementation of its 
previously approved pretreatment program if the Approval Authority 
determines that the primary objectives of the Local Pilot Pretreatment 
Program are not being met or the ``Project XL'' agreement expires or is 
otherwise terminated.

           Appendix A to Part 403--Program Guidance Memorandum

                  U.S. Environmental Protection Agency

                           December 16, 1975.

                     Program Guidance Memorandum--61

Subject: Grants for Treatment and Control of Combined Sewer Overflows 
          and Stormwater Discharges.
From: John T. Rhett, Deputy Assistant Administrator for Water Program 
          Operations (WH-546).
To: Regional Administrators, Regions I-X.

    This memorandum summarizes the Agency's policy on the use of 
construction grants for treatment and control of combined sewer 
overflows and stormwater discharges during wet-weather conditions. The 
purpose is to assure that projects are funded only when careful planning 
has demonstrated they are cost-effective.

                       I. Combined Sewer Overflows

                              A. Background

    The costs and benefits of control of various portions of pollution 
due to combined sewer overflows and by-passes vary greatly with the 
characteristics of the sewer and treatment system, the duration, 
intensity, frequency and areal extent of precipitation, the type and 
extent of development in the service area, and the characteristics, uses 
and water quality standards of the receiving waters. Decisions on grants 
for control of combined sewer overflows, therefore, must be made on a 
case-by-case basis after detailed planning at the local level.
    Where detailed planning has been completed, treatment or control of 
pollution from wet-weather overflows and bypasses may be given priority 
for construction grant funds only after provision has been made for 
secondary treatment of dry-weather flows in the area. The detailed 
planning requirements and criteria for project approval follow.

                        B. Planning Requirements

    Construction grants may be approved for control of pollution from 
combined sewer overflows only if planning for the project was thoroughly 
analyzed for the 20 year planning period:
    1. Alternative control techniques which might be utilized to attain 
various levels of pollution control (related to alternative beneficial 
uses, if appropriate), including at least initial consideration of all 
the alternatives described in the section on combined sewer and 
stormwater control in ``Alternative Waste Management Techniques and Best 
Practicable Waste Treatment'' (Section C of Chapter III of the 
information proposed for comment in March 1974).
    2. The costs of achieving the various levels of pollution control by 
each of the techniques appearing to be the most feasible and cost-
effective after the preliminary analysis.
    3. The benefits to the receiving waters of a range of levels of 
pollution control during wet-weather conditions. This analysis will 
normally be conducted as part of State water quality management 
planning, 208 areawide management planning, or other State, regional or 
local planning effort.
    4. The costs and benefits of addition of advanced waste treatment 
processes to dry-weather flows in the area.

                    C. Criteria for Project Approval

    The final alternative selected shall meet the following criteria:
    1. The analysis required above has demonstrated that the level of 
pollution control provided will be necessary to protect a beneficial use 
of the receiving water even after technology based standards required by 
Section 301 of Pub. L. 92-500 are achieved by industrial point sources 
and at least secondary treatment is achieved for dry-weather municipal 
flows in the area.

[[Page 51]]

    2. Provision has already been made for funding of secondary 
treatment of dry-weather flows in the area.
    3. The pollution control technique proposed for combined sewer 
overflow is a more cost-effective means of protecting the beneficial use 
of the receiving waters than other combined sewer pollution control 
techniques and the addition of treatment higher than secondary treatment 
for dry-weather municipal flows in the area.
    4. The marginal costs are not substantial compared to marginal 
benefits.
    Marginal costs and benefits for each alternative may be displayed 
graphically to assist with determining a project's acceptability under 
this criterion. Dollar costs should be compared with quantified 
pollution reduction and water quality improvements. A descriptive 
narrative should also be included analyzing monetary, social and 
environmental costs compared to benefits, particularly the significance 
of the beneficial uses to be protected by the project.

                        II. Stormwater Discharges

    Approaches for reducing pollution from separate stormwater 
discharges are now in the early stages of development and evaluation. We 
anticipate, however, that in many cases the benefits obtained by 
construction of treatment works for this purpose will be small compared 
with the costs, and other techniques of control and prevention will be 
more cost-effective. The policy of the Agency is, therefore, that 
construction grants shall not be used for construction of treatment 
works to control pollution from separate discharges of stormwater except 
under unusual conditions where the project clearly has been demonstrated 
to meet the planning requirements and criteria described above for 
combined sewer overflows.

                       III. Multi-purpose Projects

    Projects with multiple purposes, such as flood control and 
recreation in addition to pollution control, may be eligible for an 
amount not to exceed the cost of the most cost-effective single purpose 
pollution abatement system. Normally the Separable Costs-Remaining 
Benefits (SCRB) method should be used to allocate costs between 
pollution control and other purposes, although in unusual cases another 
method may be appropriate. For such cost allocation, the cost of the 
least cost pollution abatement alternative may be used as a substitute 
measure of the benefits for that purpose. The method is described in 
``Proposed Practices for Economic Analysis of River Basin Projects,'' 
GPO, Washington, D.C., 1958, and ``Efficiency in Government through 
Systems Analysis,'' by Roland N. McKean, John Wiley & Sons, Inc., 1958.
    Enlargement of or otherwise adding to combined sewer conveyance 
systems is one means of reducing or eliminating flooding caused by wet-
weather conditions. These additions may be designed so as to produce 
some benefits in terms of reduced discharge of pollutants to surrounding 
waterways. The pollution control benefits of such flood control 
measures, however, are likely to be small compared with the costs, and 
the measures therefore would normally be ineligible for funding under 
the construction grants program.
    All multi-purpose projects where less than 100% of the costs are 
eligible for construction grants under this policy shall contain a 
special grant condition precluding EPA funding of non-pollution control 
elements. This condition should, as a minimum, contain a provision 
similar to the following:
``The grantee explicitly acknowledges and agrees that costs are 
allowable only to the extent they are incurred for the water pollution 
control elements of this project.''
    Additional special conditions should be included as appropriate to 
assure that the grantee clearly understands which elements of the 
project are eligible for construction grants under Pub. L. 92-500.

  Appendix D to Part 403--Selected Industrial Subcategories Considered 
         Dilute for Purposes of the Combined Wastestream Formula

    The following industrial subcategories are considered to have dilute 
wastestreams for purposes of the combined wastestream formula. They 
either were or could have been excluded from categorical pretreatment 
standards pursuant to paragraph 8 of the Natural Resources Defense 
Council, Inc., et al. v. Costle Consent Decree for one or more of the 
following four reasons: (1) The pollutants of concern are not detectable 
in the effluent from the industrial user (paragraph 8(a)(iii)); (2) the 
pollutants of concern are present only in trace amounts and are neither 
causing nor likely to cause toxic effects (paragraph 8(a)(iii)); (3) the 
pollutants of concern are present in amounts too small to be effectively 
reduced by technologies known to the Administrator (paragraph 
8(a)(iii)); or (4) the wastestream contains only pollutants which are 
compatible with the POTW (paragraph 8(b)(i)). In some instances, 
different rationales were given for exclusion under paragraph 8. 
However, EPA has reviewed these subcategories and has determined that 
exclusion could have occurred due to one of the four reasons listed 
above.
    This list is complete as of October 9, 1986. It will be updated 
periodically for the convenience of the reader.

               Appendix E to Part 403--Sampling Procedures

                           I. Composite Method

    A. It is recommended that influent and effluent operational data be 
obtained through 24-hour flow proportional composite samples. Sampling 
may be done manually or automatically, and discretely or continuously. 
If discrete sampling is employed, at least 12 aliquots should be 
composited. Discrete sampling may be flow proportioned either by varying 
the time interval between each aliquot or the volume of each aliquot. 
All composites should be flow proportional to either the stream flow at 
the time of collection of the influent aliquot or to the total influent 
flow since the previous influent aliquot. Volatile pollutant aliquots 
must be combined in the laboratory immediately before analysis.
    B. Effluent sample collection need not be delayed to compensate for 
hydraulic detention unless the POTW elects to include detention time 
compensation or unless the Approval Authority requires detention time 
compensation. The Approval Authority may require that each effluent 
sample is taken approximately one detention time later than the 
corresponding influent sample when failure to do so would result in an 
unrepresentative portrayal of actual POTW operation. The detention 
period should be based on a 24-hour average daily flow value. The 
average daily flow should in turn be based on the average of the daily 
flows during the same month of the previous year.

                             II. Grab Method

    If composite sampling is not an appropriate technique, grab samples 
should be taken to obtain influent and effluent operational data. A grab 
sample is an individual sample collected over a period of time not 
exceeding 15 minutes. The collection of influent grab samples should 
precede the collection of effluent samples by approximately one 
detention period except that where the detention period is greater than 
24 hours such staggering of the sample collection may not be necessary 
or appropriate. The detention period should be based on a 24-hour 
average daily flow value. The average daily flow should in turn be based 
upon the average of the daily flows during the same month of the 
previous year. Grab sampling should be employed where the pollutants 
being evaluated are those, such as cyanide and phenol, which may not be 
held for an extended period because of biological, chemical or physical 
interaction which take place after sample collection and affect the 
results.
