OMB does not
approve the proposed revisions at this time. EPA must document the
practical utility of the proposed additional requirements
Specifically, the agency should answer the following questions: 1.
Without the new requirements, what is the potential for current
plants to cause exceedences of the ambient 1 ug/m3 average? 2. What
information leads the agency to doubt that plants are maintaining
and operating this control equipment properly? 3. Why are hourly
measurements necessary? 4. Would daily measurements achieve the
same goal? 5. Are temperature measurements necessary during the
colder season for devices that cool with tap water? 6. Why are any
reports necessary within 10 days of a parameter exceedence? 7. Why
are the semi-annual reports necessary? Please use OMB comment
number 2060-0097 when reporting to these remark
