As a first step in assessing POTW start-up costs, POTWs should look 
at the overall functional responsibilities which they must meet for a 
pretreatment program. In a large POTW, many of these functions would 
be met by an entire division or department. In a small POTW, the same 
people might fulfill several of these responsibilities. The important 
factor is that each of the following responsibilities be addressed: sampling 
and industrial review; lab analyses, technical and engineering assistance; 
legal assistance; adjudication; and cverall administration. Special equip-— 
ment requirements fall into the areas of field sampling of industrial 
wastes and subsequent laboratory analyses. 
Sampling and Industrial Review 
While the present Federal Pretreatment Regulations are based to a 
large extent on self-monitoring, there appears to be movement away from 
extensive self-monitoring on the part of the industries. At a minimun, 
it is essential that each of the "significant" industries in.a POTW service 
area be. sampled twice .a year. Problem or recalcitrant industries require 
substantially more effort to locate and define the problem and dev ‘op 
a case for enforcement. 
In any event, the provision of a field crew or crews is an essential 
part of POTW Pretreatment Program. Depending upon the nature of the activities 
to be performed by these people, their qualifications can vary. The people 
performing the field sampling and industrial review should be of sufficient 
qualification and training to be able to do an in-plant review of major 
process lines, discuss the processes and sampling techniques with plant 
Management, install and maintain the sampling equipment, and retrieve 
the samples. A two-person crew is generally adequate for most sampling 
situations. It is desirable that at least one member of the crew have 
substantial field experience and advance education at the community college 
or college level. : 
It is estimated that approximately four (4) to eight (8) crew hours 
are required to contact a moderately complex industry, obtain information 
on its plant processing, flow characteristics, etc., and to actually install 
and maintain the monitoring equipment. More complex plants or enforcement 
Problems would greatly magnify the time required. 
After an industrial plant has been thoroughly reviewed, sampling 
routine and locations established, and compliance achieved, a two-person 
crew should be able to handle between 150 to 200 moderately complex industries 
with a twice a year sampling frequency. The cost for such personnel 
would vary, depending upon the wage scales in the area, but it is not 
unreasonable to assume that salaries in the range of $13,000 to $20,000, 
depending upon qualifications, experience, and responsibility are appro- 
Priate. Figure 5-1 summarizes the equipment necessary to outfit one (1) 
two-person industrial waste sampling crew. The prices indicated will 
vary from one area of the country to another, but these are reasonably 
Tepresentative of the costs that are involved. 
As can be seen, the equipment needed for one POTW industrial waste 
Pretreatment sampling and review crew will require approximately $24,950. 
Present Construction Grant Guidelines indicate that most of this equipment
