this subpart, you must develop and make available for 

inspection by the delegated authority, upon request, a 

site-specific monitoring plan. The plan must specify the 

process parameters established during the initial 

compliance assessment and how they are being monitored and 

maintained to demonstrate continuous compliance. 

(h) If you would like to use parameters or means 

other than those specified in Table 4 of this subpart to 

demonstrate continuous compliance with the emission limits 

specified in Tables 1 and 2 of this subpart, you must apply

17

demonstrate continuous compliance.

(i) At all times the owner or operator must operate 

and maintain any affected source, including associated air 

pollution control equipment and monitoring equipment, in a 

manner consistent with safety and good air pollution 

control practices for minimizing emissions. The general 

duty to minimize emissions does not require the owner or 

operator to make any further efforts to reduce emissions if 

levels required by this standard have been achieved. 

Determination of whether such operation and maintenance 

procedures are being used will be based on information 

available to the Administrator which may include, but is 

not limited to, monitoring results, review of operation and 

maintenance procedures, review of operation and maintenance 

records, and inspection of the source.

with the emission limits specified in Tables 1 and 2 of 

this subpart, you must develop and make available for 
18

inspection by the delegated authority, upon request, a 

site-specific monitoring plan. The plan must specify the 

process parameters established during the initial 

compliance assessment and how they are being monitored and 

maintained to demonstrate continuous compliance. 

(m) If you would like to use parameters or means 

other than those specified in Table 4 of this subpart to 

demonstrate continuous compliance with the emission limits 

specified in Tables 1 and 2 of this subpart, you must apply 

to the Administrator for approval of an alternative

monitoring plan under §63.8(f). The plan must specify how 

process parameters established during the initial 

compliance assessment will be monitored and maintained to 

demonstrate continuous compliance.

(n) At all times the owner or operator must operate 

and maintain any affected source, including associated air 

pollution control equipment and monitoring equipment, in a 

manner consistent with safety and good air pollution 

control practices for minimizing emissions. The general 

duty to minimize emissions does not require the owner or 

operator to make any further efforts to reduce emissions if 

levels required by this standard have been achieved. 

Determination of whether such operation and maintenance 
19

procedures are being used will be based on information 

available to the Administrator which may include, but is 

not limited to, monitoring results, review of operation and 

maintenance procedures, review of operation and maintenance 

records, and inspection of the source.

coating mixers, and coaters used to apply asphalt to 

substrate to manufacture roofing products (e.g., shingles, 

roll roofing). 

Asphalt processing operation means any operation 

engaged in the preparation of asphalt flux at stand-alone 

asphalt processing facilities, petroleum refineries, and 

asphalt roofing facilities. Asphalt preparation, called 

“blowing,” is the oxidation of asphalt flux, achieved by 

bubbling air through the heated asphalt, to raise the 

softening point and to reduce penetration of the oxidized 

asphalt. An asphalt processing facility includes one or 

more asphalt flux blowing stills. 

Asphalt roofing manufacturing operation means the 

collection of equipment used to manufacture asphalt roofing 

products through a series of sequential process steps. The 

equipment configuration of an asphalt roofing manufacturing 

process varies depending upon the type of substrate used 

(i.e., organic or inorganic). For example, an asphalt 

roofing manufacturing line that uses organic substrate 

(e.g., felt) typically would consist of a saturator (and 

wet looper), coating mixer, and coater (although the 

saturator could be bypassed if the line manufacturers 

multiple types of products). An asphalt roofing 
28

manufacturing line that uses inorganic (fiberglass mat) 

substrate typically would consist of a coating mixer and 

coater. 

Blowing still means the equipment in which air is 

blown through asphalt flux to change the softening point 

and penetration rate of the asphalt flux, creating oxidized 

asphalt. 

Built-up roofing operations means operations involved 

in the on-site (e.g., at a commercial building) assembly of 

roofing system components (e.g., asphalt, substrate, surface 

granules). 

Coater means the equipment used to apply amended 

(filled or modified) asphalt to the top and bottom of the 

substrate (typically fiberglass mat) used to manufacture 

shingles and rolled roofing products. 

Coating mixer means the equipment used to mix coating 

asphalt and a mineral stabilizer, prior to applying the 

stabilized coating asphalt to the substrate. 

Hot-mix asphalt operation means operations involved in 

mixing asphalt cement and aggregates to produce materials 

for paving roadways and hardstand (e.g., vehicle parking 

lots, prepared surfaces for materiel storage). 

Particulate matter (PM) means, for the purposes of 
29

this subpart, includes any material determined 

gravimetrically using EPA Method 5A - Determination of 

Particulate Matter Emissions From the Asphalt Processing 

And Asphalt Roofing Industry (40 CFR Part 60, Appendix A3). 

Responsible official is defined in § 63.2. 

Saturator means the equipment used to impregnate a 

substrate (predominantly organic felt) with asphalt. 

Saturators are predominantly used for the manufacture of 

rolled-roofing products (e.g., saturated felt). For the 

purposes of this subpart, the term saturator includes 

impregnation vat and wet looper. 

Wet looper means the series of rollers typically 

following the saturator used to provide additional 

absorption time for asphalt to penetrate the roofing 

substrate.

authority to your State, local, or tribal agency, then that 

agency, in addition to the U.S. EPA, has the authority to 
30

implement and enforce this subpart. You should contact 

your U.S. EPA Regional Office to find out if implementation 

and enforcement of this subpart is delegated. 

(b) In delegating implementation and enforcement 

authority of this subpart to a State, local, or tribal 

agency under 40 CFR part 63, subpart E, the following 

authorities are retained by the Administrator of U.S. EPA: 

(1) Approval of alternatives to the requirements in 

§§63.11559, 63.11560, 63.11561, 63.11562, and 

63.11563. 

(2) Approval of major changes to test methods under 

§63.7(e)(2)(ii) and (f) and as defined in §63.90. 

(3) Approval of major changes to monitoring under 

§63.8(f) and as defined in §63.90. 

(4) Approval of major changes to recordkeeping and 

reporting under §63.10(f) and as defined in §63.90.
