7011.0922 OPERATIONAL REQUIREMENTS AND LIMITATIONS FROM PERFORMANCE TESTS.

Subpart 1.

Throughput limit.

The owner or operator of a hot mix asphalt plant shall not exceed the production throughput at which compliance with part 7011.0905 or 7011.0909 was demonstrated during the plant's most recent performance test, unless authorized by subpart 2.

Subp. 2.

Certain exceptions to throughput limit.

Except as provided in items A and B, if a hot mix asphalt plant demonstrated compliance for particulate matter and opacity during its most recent performance test and its tested emission rate (gr/dscf or lb/hr) was less than 80 percent of the applicable rule or permit emission limit, then the owner or operator may increase production throughput ten percent over that allowed under subpart 1.

A.

If a hot mix asphalt plant with a fabric filter control device has conducted a performance test since January 1, 1991, has demonstrated compliance for particulate matter and opacity, and its tested emission rate (gr/dscf or lb/hr) was less than 50 percent but greater than or equal to 25 percent of the applicable rule or permit emission limit, then the owner or operator may increase production throughput 15 percent over that allowed under subpart 1.

B.

If a hot mix asphalt plant with a fabric filter control device has conducted a performance test since January 1, 1991, has demonstrated compliance for particulate matter and opacity, and its tested emission rate (gr/dscf or lb/hr) was less than 25 percent of the applicable rule or permit emission limit, then the owner or operator may increase production throughput 20 percent over that allowed by subpart 1.

Subp. 3.

Monitoring and record keeping required.

To determine compliance with subpart 1, the owner or operator of a hot mix asphalt plant must:

A.

operate an accumulating hour meter on the dryer burner at all times the dryer burner is in operation;

B.

record each day the plant's hours of operation as determined by the hour meter and total tons of hot mix asphalt produced; and

C.

determine the production throughput by dividing the total tons of hot mix asphalt produced by the hours of operation for each calendar day of operation.
