Current through Register Vol. 48, No. 6, June 28, 2024
The HWCAQSP is a combined calculation/reference table
					 approach for conservatively estimating short-term and annual average facility
					 impacts for stack emissions. The procedure is based on extensive short-term
					 modeling of 11 generic source types and on a set of adjustment factors for
					 estimating annual average concentrations from short-term concentrations.
					 Facility impacts may be determined based on the selected worst-case stack or on
					 multiple stacks, in which the impacts from each stack are estimated separately
					 and then added to produce the total facility impact.
This procedure is most useful for facilities with multiple
					 stacks, large source-to-property boundary distances, and complex terrain
					 between 1 and 5 km from the facility. To ensure a sufficient degree of
					 conservatism, the HWCAQSP may not be used if any of the five screening
					 procedure limitations listed below are true:
oThe facility is located in a narrow valley less than 1 km
					 wide;
oThe facility has a stack taller than 20 m and is located
					 such that the terrain rises to the stack height within 1 km of the
					 facility;
oThe facility has a stack taller than 20 m and is located
					 within 5 km of the shoreline of a large body of water;
oThe facility property line is within 200 m of the stack
					 and the physical stack height is less than 10 m; or
oOn-site receptors are of concern, and stack height is less
					 than 10 m.
If any of these criteria are met or the Department
					 determines that this procedure is not appropriate, then detailed site-specific
					 modeling or modeling using the "Screening Procedures for Estimating the Air
					 Quality Impact of Stationary Sources," EPA -450/4-88-010, Office of Air Quality
					 Planning and Standards, August 1988, is required. Detailed site-specific
					 dispersion modeling must conform to the EPA "Guidance on Air Quality Models
					 (Revised)", EPA 450/2-78-027R, Office of Air Quality Planning and Standards,
					 Research Triangle Park, North Carolina, July 1986. This document provides
					 guidance on both the proper selection and regulatory application of air quality
					 models.
Introduction
The Hazardous Waste Combustion Air Quality Screening
					 Procedure (HWCAQSP) (also referred to hereafter as "the screening procedure" or
					 "the procedure") provides a quick, easy method for estimating maximum (hourly)
					 and annual average ambient air impacts associated with the combustion of
					 hazardous waste. The methodology is conservative in nature and estimates
					 dispersion coefficients [FN1] based on facility-specific information.
The screening procedure can be used to determine emissions
					 limits at sites where the nearest meteorological (STAR) station is not
					 representative of the meteorology at the site. If the screen shows that
					 emissions from the site are adequately protective, then the need to collect
					 site-specific meteorological data can be eliminated.
The screening procedure is generally most helpful for
					 facilities meeting one or more of the following conditions:
oMultiple stacks with substantially different release
					 specifications (e.g., stack heights differ by >=50 percent, exit
					 temperatures differ by >=50 °K, or the exit flow rates differ by more than a
					 factor of 2),
oTerrain located between 1 km and 5 km from the site
					 increases in elevation by more than the physical height of the shortest stack
					 (i.e., the facility is located in complex terrain), or
oSignificant distance between the facility's stacks and the
					 site boundary [guidance on determining whether a distance is "significant" is
					 provided in Step 6(B) of the procedure].
Steps 1 through 9 of the screening procedure present a
					 simplified method for determining emissions based on the use of the
					 "worst-case" stack. If the simplified method shows that desired feed rates
					 result in emissions that exceed allowable limits for one or more pollutants, a
					 refined analysis to examine the emissions from each stack can be conducted.
					 This multiple-stack method is presented in Step 10.
The steps involved in screening methodology are as
					 follows:
Step 1. Define Source Characteristics
Step 2. Determine the Applicability of the Screening
					 Procedure
Step 3. Select the Worst-Case Stack
Step 4. Verify Good Engineering Practice (GEP)
					 Criteria
Step 5. Determine the Effective Stack Height and
					 Terrain-Adjusted Effective Stack Height
Step 6. Classify the Site as Urban or Rural
Step 7. Determine Maximum Dispersion Coefficients
Step 8. Estimate Maximum Ambient Air Concentrations
Step 9. Determine Compliance With Regulatory Limits
Step 10. Multiple Stack Method
Step 1: Define Source Characteristics
Provide the following source data: [FN2]
FOOTNOTE: [FN2] Worksheet space is provided for three
					 stacks, if the facility has additional stacks, copy the form and revise stack
					 identification numbers for 4, 5, etc.
Stack Date
Stack No. 1
Stack No. 2
Stack No. 3
Physical stack height (m)
______
______
______
Exhaust temperature (° K)
______
______
______
Flow rate (m/sec)
______
______
______
Nearby Building Dimensions
Consider all buildings within five building heights or five
					 maximum projected widths of the stack(s). For the building with the greatest
					 height, fill in the spaces below.
Building Height (m)____________________________
Maximum projected building width (m)________________
Nearby Terrain Date
Determine maximum terrain rise for the following three
					 distance ranges from
the facility (not required if the highest stack is less
					 than 10 m in height):
__________(m) __________(m) __________(m)
0-0.5 km 0-2.5 km 0-5 km
Distance from facility to nearest shoreline
					 (km)__________
Valley width (km)_________________________
Step 2: Determine the Applicability of the Screening
					 Procedure
Fill in the following data:
Yes
No
Is the facility in a valley < km in
								width?
______________
Is the terrain rise within 1 km of the facility
								greater than the physical stack height of the tallest stack? (Only applies to
								stacks <=20 meters in height)
______________
Is the distance to the nearest shoreline <5 km?
								(Only applies to facilities with stacks <=20 meters in
								height)
______________
For the building listed in Step 1, is the closest
								property boundary <5 times the building height or <5 times the maximum
								projected building width? (Only applies to facilities with a stack height
								<2.5 times the building height)
______________
If the answer is "no" to all the preceding questions, then
					 the HWCAQSP is acceptable. If the answer to any question is "yes", the
					 procedure is not acceptable.
Step 3: Select the Worst-Case Stack
If the facility has several stacks, a worst-case stack must
					 be chosen to conservatively represent release conditions at the facility.
					 Follow the steps below to identify the worst-case stack.
Apply the following equation to each stack:
K = HVT
where:
K= an arbitrary parameter accounting for the relative
					 influence of the stack
height and plume rise.
H= Physical stack height (m)
V= Flow rate (m/sec)
T= Exhaust temperature (K)
Complete the following table to compute the "K" value for
					 each stack:
Stack No.

Select the stack with the lowest "K" value. This is the
					 worst-case stack that will be used for Steps 4 through 9.
Worst-Case Stack is identified as Stack No. ____
Step 4: Verify Good Engineering Practice (GEP)
					 Criteria
Confirm that the selected worst-case stack meets Good
					 Engineering Practice (GEP) criteria. The stack height to be used in the
					 subsequent steps of this procedure must not be greater than the maximum GEP.
					 Maximum and minimum GEP stack heights are defined as follows:
CEP (minimum)=H + (1.5 x L)
GEP (maximum)=greater of 65 m or
H+(1.5 x L)
where:
H= height of the building selected in Step 1 measured from
					 ground level
elevation at the base of the stack
L= the lesser dimension of the height or projected width of
					 the building
selected in Step 1
Record the following data for the worst-case stack:
Stack height (m) =_______
H(m)=____________________
L(m)=____________________
Then compute the following:
GEP (minimum) (m) = _____
GEP (maximum) (m) = _____
* If the physical height of the worst-case stack exceeds
					 the maximum GEP, then use the maximum GEP stack height for the subsequent steps
					 of this analysis;
* If the physical height of the worst-case stack is less
					 than the minimum GEP, then use generic source number 11 as the selected source
					 for further analysis and proceed directly to Step 6;
* If the physical height of the worst-case stack is between
					 the minimum and maximum GEP, then use the actual physical stack height for the
					 subsequent steps of this analysis.
Step 5: Determine the Effective Stack Height and the
					 Terrain-Adjusted Effective
Stack Height (TAESH)
The effective stack height is an important factor in
					 dispersion modeling. The effective stack height is the physical height of the
					 stack plus plume rise. As specified in Step 4, the stack height used to
					 estimate the effective stack height must not exceed GEP requirements. Plume
					 rise is a function of the stack exit gas temperature and flow rate.
In this analysis, the effective stack height is used to
					 select the generic source that represents the dispersion characteristics of the
					 facility. For facilities located in flat terrain and for all facilities with
					 worst-case stacks less than or equal to 10 meters in height, generic source
					 numbers are selected strictly on the basis of effective stack height. In all
					 other cases, the effective stack height is further adjusted to take into
					 account the terrain rise near the facility. This "terrain-adjusted effective
					 stack height" (TAESH) is then used to select the generic source number that
					 represents the dispersion characteristics of the facility. Follow the steps
					 below to identify the effective stack height, the TAESH (where applicable), and
					 the corresponding generic source number.
(A) Go to Table 5.0-1 and find the plume rise
				  value corresponding to the stack temperature and exit flow rate for the
				  worst-case stack determined in Step 3.
Plume rise= ______(m)
(B) Add the plume rise to the GEP stack
				  height of the worst-case stack determined in Steps 3 and 4.
GEP stack height (m)
+
Plume rise (m)
=
Effective stack height(m)
____________________
+
______________
=
_______________
(C) Go to the first column of Table 5.0-2 and
				  identify the range of effective stack heights that includes the effective stack
				  height estimated in Step 5(B). Record the generic source number that
				  corresponds to this range. Generic source number =______
(D) If the source is located in flat terrain
				  [FN3], or if the generic source number identified in Step 5(C) above is 1 or 11
				  (regardless of terrain classification), use the generic source number
				  determined in Step 5(C) and proceed directly to Step 6. Otherwise, continue to
				  Step 5(E).
(E) For those situations
				  where the conditions in Step 5(D) do not apply, the effective stack height must
				  be adjusted for terrain. The TAESH for each distance range is computed by
				  subtracting the terrain rise within the distance range from the effective stack
				  height. [FN4]
FOOTNOTE: [FN3] The terrain is considered flat and terrain
					 adjustment factors are not used if the maximum terrain rise within 5 km of the
					 facility (see Step 1) is less than 10 percent of the physical stack height of
					 the worst-case stack.
FOOTNOTE: [FN4] Refer to Step 1 for terrain adjustment
					 data. Note that the distance from the source to the outer radii of each range
					 is used. For example, for the range >0.5-2.5 km, the maximum terrain rise in
					 the range 0.0-2.5 km is used.

Step 6: Classify the Site as Urban or Rural
(A) Classify the land use near the facility
				  as either urban or rural by determining the percentage of urban land use types
				  (as defined in Table 3; for further guidance see the footnoted references) that
				  fell within 3 km of the facility. [FN5]
FOOTNOTE: [FN5] The delineation of urban and rural areas,
					 can be difficult for the residential-type areas listed in Table 5.0-3. The
					 degree of resolution in Table 5.0-3 for residential areas often cannot be
					 identified without conducting site area inspections. This process can require
					 extensive analysis, which, for many applications, can be greatly streamlined
					 without sacrificing confidence in selecting the appropriate urban or rural
					 classification. The fundamental simplifying assumption is based on the premise
					 that many applications will have clear-cut urban/rural designations, i.e., most
					 will be in rural settings that can be definitively characterized through a
					 review of aerial photographs, zoning maps, or U.S. Geological Survey
					 topographical maps.

If the minimum distance between any stack and the nearest

					 buffer distance is considered significant and the facility is likely to benefit
					 from use of the HWCAQSP relative to the Tier I and II limits (see discussion of
					 benefits from using HWCAQSP in introduction section).
Step 7: Determine Maximum Dispersion Coefficients
(A) Determine maximum average hourly
				  dispersion coefficients. Based on the results of Step 6(A), select either Table
				  5.0-4 (urban) or Table 5.0-5 (rural) to determine the maximum average hourly
				  dispersion coefficient. [FN6] For flat terrain [defined in Step 5(D) ] and for
				  all sites with generic source numbers 1 or 11, use Step 7(A)(1). For rolling or
				  complex terrain (excluding generic sources numbers 1 and 11), use Step 7(A)(2).
(1) Search down the appropriate generic
				  source number column (based on Step 5(C)), beginning at the minimum fenceline
				  distance listed in Step 6(B). [FN7] Record the maximum average hourly
				  dispersion coefficient encountered. Maximum Average Hourly Dispersion
				  Coefficient = _____ (/m/g/sec)
(2)
				  For each of the three distance-based generic source numbers listed in Step
				  5(E), search down the appropriate generic source number columns, beginning at
				  the minimum fenceline distance listed in Step 6(B). Note that different columns
				  may be used for each of the three distance ranges if there is a need for
				  terrain adjustment. Record the maximum dispersion coefficient for each generic
				  source number.
