PART Env-A 2102  EMISSION STANDARDS FOR PARTICULATE MATTER

 

          Env-A 2102.01  Applicability.

 

          (a)    Subject to (b), below, this part shall apply to any stationary source or device that is a source of particulate matter emissions discharged to the ambient air through a stack or through an exhaust and ventilation system.

 

          (b)    Those sources of particulate matter emissions that are governed specifically by other chapters, parts, or sections of this subtitle shall be controlled by those particular chapters, parts, or sections.

          Env-A 2102.02  Definitions.  “Exhaust and ventilation system” means any system that removes and transports particulate matter from the point of generation to the ambient air.

          Env-A 2102.03  Emission Standards for Particulate Matter.

 

          (a)  For any stationary source or device installed after February 18, 1972, the owner or operator shall not cause or allow the emission of particulate matter at such source or device to exceed the emission standards specified for “New Devices” as listed in Table 2102-1, in (c), below.

 

          (b)  For any stationary source or device installed prior to or on February 18, 1972, the owner or operator shall not cause or allow the emission of particulate matter at such source or device to exceed the emission standards specified for “Existing Devices” as listed in Table 2102-1, in (c), below.

 

          (c)  Particulate matter emission standards shall be as set forth in Table 2102-1, below:

          Env-A 2102.04  Calculation of Particulate Matter Emission Standards.

 

          (a)  Where the process weight rate is not explicitly listed in Table 2102-1, the maximum allowable particulate matter emission rate shall be calculated using the applicable equation in (b) or (c), below, where:

 

(1)  “E” means the maximum allowable particulate matter emission rate in pounds per hour (lb/hr); and

 

(2)  “P” means the process weight rate in tons per hour (tons/hr).

 

          (b)  For a stationary source or device installed prior to or on February 18, 1972, if the process weight rate is:

 

(1)  Up to 30 tons/hr, P shall be raised to the 0.67 power and multiplied by 5.05, as shown in the formula below:

 

E = 5.05 P0.67

 

(2)  In excess of 30 tons/hr, P shall be raised to the 0.11 power and multiplied by 66.0, and then 48 shall be subtracted from that result, as shown in the formula below:

 

E = 66.0 P0.11 - 48

 

          (c)  For a stationary source or device installed after February 18, 1972, if the process weight rate is:

 

(1)  Up to 30 tons/hr, P shall be raised to the 0.67 power and multiplied by 4.10, as in the formula below:

 

E = 4.10 P0.67

 

(2)  In excess of 30 tons/hr, P shall be raised to the 0.11 power and multiplied by 55.0, and then 40 shall be subtracted from that result, as in the formula below:

 

E = 55.0 P0.11 - 40

PART Env-A 2103  VISIBLE EMISSION STANDARDS

 

          Env-A 2103.01  Applicability.

 

          (a)  Subject to (b), below, this part shall apply to any stationary source or device that is a source of visible emissions.

 

          (b)  Those sources of visible emissions that are governed specifically by other chapters, parts, or sections of this subtitle shall be controlled by those particular chapters, parts, or sections.

          Env-A 2103.02  Visible Emission Standards.

 

          (a)  The owner or operator shall not cause or allow visible emissions from any stationary source or device subject to this part to exceed an average of 20 percent opacity for any continuous 6-minute period.

 

          (b)  Opacity shall be determined in accordance with Env-A 807.
