|
| |
(3)
|
No person shall operate a medical waste incinerator unless the bottom ash, fly ash and scrubber residuals
are handled and stored in a manner that prevents entrainment into ambient air |
| |
(4)
|
The owner or operator of a medical waste incinerator shall maintain the following:
|
(A)
|
A continuous data recording system which provides for each day of operation continuous recording of the primary
and secondary combustion chamber temperatures; carbon monoxide emissions; the key operating parameters of
the air pollution control equipment, as specified by the district Air Pollution Control Officer; the
hourly waste charging rates; and the opacity of stack emissions or other indicator of particulate matter
which is approved by the district air pollution control officer; |
|
(B)
|
Maintenance records for the incinerator, control equipment, and monitoring equipment; and calibration records
for the monitoring equipment; and |

(5)
|
For purposes of demonstrating compliance with subsection (b)(1) of this rule the owner or operator of a medical
waste incinerator shall conduct a minimum of two annual source tests for the dioxins stack emissions
using ARB Test Method 428, and a minimum of three sampling runs shall be conducted for the method.
Annual source tests shall be conducted until at least two consecutive tests demonstrate
compliance, at which time the frequency of future source tests is at the discretion
of the Air Pollution Control Officer. For purposes of determining compliance with subsection (b)(1)(A)
of this rule, emissions shall be sampled simultaneously from the flue at a location downstream of
the last combustion chamber, but prior to the control equipment, and from the stack during
source testing. For purposes of determining compliance with subsection (b)(1)(B) of this rule, the source
testing shall be conducted at the stack. The information regarding the composition (moisture content, and amount
of the total waste that is infectious, pathological, hazardous, or radioactive) and feed rate of the
fuel charged during the source test shall be provided with the test results. The district Air Pollution
Control Officer can require additional necessary information regarding the composition of the waste.
Source testing shall be conducted at the maximum waste firing capacity (± 10 percent) allowed by the
air district permit. A copy of all source test results conducted for purposes of demonstrating compliance
with this rule shall be provided to the ARB at the same time that it is provided to the local air pollution
control district. |

for the operators and maintenance engineers shall be submitted to the districts and the original certificates
shall be available for inspection at the facility with the permit to operate. |
