The General Permit does not convey any property rights of any sort, or any
exclusive privilege.
(4) The
operator shall maintain and operate as necessary all emission units and air
pollution systems required by the general permit in a manner consistent with
good air pollution control practice for minimizing emissions.

other cause indicate to the Department that equipment may be operating out of
compliance with emission standards or license conditions; or
(ii) pursuant to any other requirement of
this general permit to perform testing.

circumstances representative of the facility's normal process and operating
conditions indicate emissions in excess of the applicable standards, then:
(a) within thirty (30) days following receipt
of such test results, the operator shall re-test the non-complying emission
source under circumstances representative of the facility's normal process and
operating conditions and in accordance with the Department's air emission
compliance test protocol and 40 CFR Part 60 or other method approved or
required by the Department;
(b) the
days of violation shall be presumed to include the date of test and each and
