additional public comment—this usu ally occurs when substantial modifica tions have been made in the initial proposal. Publication as a "tentative final" regulation with further public com ment solicited. This "tentative final" form usually designates a "firmer" proposal by the agency, and one which is less likely to change in significant respects when eventually issued in final text. Issuance of final regulations—no comments solicited. This represents the final phase in an agency's regula tory development. Dissatisfaction by interested parties with this promul gated regulation must now be taken up via the judicial process, which can involve court challenge, a request for stay of the effective date, etc. No publication at all or publication of a statement that terminates agency efforts to issue regulations at this time could also occur.
"ΤΙ recorders help our systems operate 24 hours a day." . . . says Dennis Mach, General Manager of Richmond Instruments Company, manufacturers of ex haust test systems. "We have no problems with TI recorders. They are reliable, easy to mount, clean, and easy to service. That's why we use them in the vast majority of our emission systems. We like the resolution of the wide chart and the good inking system. In addi tion, the removable back panel makes special modifications easy." "We especially like the reliable heavy-duty construction because our systems must operate with little or no down-time to keep our customers satisfied." Richmond Instruments is only one of many satisfied users of TI strip chart recorders. The chances are good that you, too, can profit from the high quality, accuracy and heavy-duty construction of the TI recorders. There's a broad selection of designs to choose from. Drives include unidirectional
and bidirectional synchro systems. Wide and dual-grid 8ervo/riter*II models give a choice of one to five full overlapping channels on a 8.75" grid. And if space saving is a requirement, the Lab/Test recorders use only 7 inches of panel height. Options include full scale adjust able zero, variable spans and inputs, electric pen lifters, felt tip or capillary inking, bidirectional take-up system, synchro or digital drives, and stepper. TI recorders are backed by more than twenty years of proven quality, reliability, accuracy and performance plus a nationwide network of sides and service offices to serve you.

Phase V—Final Regulation All regulations when finally promul gated bear an effective date for com pliance, which is usually at least 30 days after the final regulations appear in the Federal Register unless good cause is shown. Following the year in which final regulations appear in the Federal Register, they become incor porated into the Code of Federal Reg ulations, which contains all regula tions in effect for the Federal agencies. Pesticide Testing A case in point is provided by the pesticide testing guidelines (rules) proposed by the EPA in the Federal Register on July 10, 1978 (comment deadline 9/8/78), under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). Pesticides in this sense means agricultural and house hold pesticides ranging from chlordane to household disinfectant. While these regulations impact on many ana lytical laboratories in their own right, the real impact of these proposed FIFRA rules is reflected in their intro ductory text where the EPA states it plans to propose similar testing rules under the Toxic Substances Control Act (TSCA). While the FIFRA testing guidelines only affect the pesticide in dustry, the TSCA rules will apply broadly across the whole chemical in dustry and thus affect nearly every analytical facility. Comments on these FIFRA guide lines can be sent to: Federal Register Section Technical Services Division (WH-569) Office of Pesticide Programs, EPA Room 401, East Tower 401 M Street, S.W.
