A4. PROJECT/TASK ORGANIZATION

The Clean Air Act of 1970 and the associated Amendments of 1990 provide statutory 

requirements for improving air quality in the United States. Quantification of air quality 

necessitates the gathering, storage, retrieval and analysis of air pollution data. These data, stored 

in the computer-based National Emission Inventory (NEI) database system, provide information 

essential to inquiry, investigation and decision-making. For example, analysis of the data may 

lead to a more thorough consideration of certain industries or certain emissions sources, it may 

provide the basis for the development or evaluation of control strategies, and it may serve as the 

basis for an evaluation of the effectiveness of regulations.

The Shelby County Health Department, through the Pollution Control Section, collects data 

pertaining to the emissions of air pollutants and reports this data in turn to the Environmental 

Protection Agency (EPA) Administrator using the Exchange Network and the EIS Gateway.

The reported data are drawn from submitted Emission Inventory Questionnaire (EIQ) 

spreadsheets for point source data. Calculations by various EPA approved methodologies are 

used for area sources. The National Mobile Inventory Model (NMIM) is used for one area 

category, and the Mobile Vehicle Emission Simulator (MOVES) for mobile source data. These 

systems are installed on the agency’s computer system at the Shelby County Health Department

in Memphis. Data are updated and retrieved through various user-generated programs in this 

system, which is accessible to users via both a Wide Area Network (WAN) and a Local Area 

Network (LAN).

Because of the importance of air emissions data, assurance of its quality is essential. A thorough 

description of the steps involved in the collection, analysis, entry, and extraction of the data are 

described below, immediately following a discussion of the roles and responsibilities of the 

people involved in these tasks.

A5. PROBLEM DEFINITION/BACKGROUND

The Quality Assurance Project Plan (QAPP) is being prepared for the development of air 

emission inventories and to meet an EPA Section 105 grant commitment. An emission 

inventory is a tabulation of all sources of air pollutant emissions, complete with the 

emissions from those sources, in a given area. Emission inventories are the fundamental 

building blocks used to develop air quality control strategies and maintenance strategies on a 

local, regional, and national level.

The Air Emissions Reporting Rule (AERR) (73 FR 76539, December 17, 2008) specifies the 

regulatory requirements for reporting emissions inventories. The reporting requirements also

dictate the requirements for emission inventory data collection and quality assurance. The 

purpose of the AERR is to simplify reporting, offer options for data collection and exchange, 

and to unify reporting dates for various categories of inventories.

The AERR establishes requirements for the reporting of sulfur oxides (SOx), volatile organic 

compounds (VOC), nitrogen oxides (NOx), carbon monoxide (CO), lead and lead 

compounds, primary PM2.5 and primary PM10 (to include condensible and filterable 

emissions of each), ammonia (NH3); and, the reporting requirements for all types of sources 

(Point, Area, Onroad mobile, Nonroad, and Biogenic). It requires reporting on an annual 

cycle for selected point (Type A) sources and a 3-Year cycle for all other (Type B, Title 5, 

Synthetic Minor and smaller) sources.

While the AERR integrates the reporting requirements of the Clean Air Act and 40 CFR 

51.321, there are some additional state implementation plan (SIP) inventory requirements 

that merit specific discussion as some inventories are developed for reasons other than the

standardized annual and triennial inventories. Differences can be due to inclusion of new 

emission factors, results from specific studies, and different inventory versions used for 

different timeframes or types of SIP submissions. In the past Shelby County has developed 

emission inventories for different pollutants to demonstrate attainment and maintenance of 

associated NAAQS, using different generation methods.

The Shelby County Health Department-Pollution Control Section (SCHD-PCS) will include 

emissions from point sources, area sources, non-road mobile sources, and on-road mobile 

sources, as called for, in each emission inventory. The SCHD-PCS will supply emissions for 

point sources drawn from source submitted emission inventory questionnaires. If needed, the 

SCHD-PCS will use the NONROAD2008a emissions model to generate emissions for offroad equipment and will use the Airport Emissions and Dispersion Model (EDMS5.1.3) to 

generate aircraft and ground support equipment emissions. Aircraft engine emissions 

occuring during landing and takeoff operations and the ground suppot equipment and 

auxiallary power units associated with the aircraft will be included in the point source 

inventory. Commercial marine emissions would be estimated from U.S. Army Corp of 

Engineers Trips and Drafts tables in concert with AP-42 emission factors with the emissions, 

whether underway or in-port, to be included in the non-point category. Rail lines operating in 

Shelby County will be surveyed to obtain data such as hours of operation and fuel 

consumption in order to develop emissions utilizing AP-42. Railyard emissions will be 

included in point source inventories. Either MOBILE6.2 or the MOVES2010a emissions 

model will be used to generate on-road mobile emissions. After March 1, 2012, only 

MOVES2010a will be used for the deveolpment of inventories for SIPs with some possible 
10

case-by-case exceptions. The SCHD-PCS will consider EPA estimates for biogenic 

emissions or will develop them in-house using BEIS3.12.

Data has been and will be provided to EPA’s National Emissions Inventory (NEI) database 

using the most current version of the NEI data format. Data will be provided in accordance 

with the National Emission Factor and Inventory Group’s website instructions on the Air 

CHIEF website and by e-mail to EPA (http://www.epa.gov/ttn/chief/eis/index.html).

In addition to use as a building block in developing air quality control and maintenance 

strategies, other specific uses of the emission inventory data include:

• State oversight of point sources

• Public Requests and Websites

• Use in the EPA National Annual Trends Report

• Emission Trading

• Compliance Demonstrations

• Document regulatory impact assessments

• Permitting

• Air Quality Assessments

• Human Exposure Modeling

A6. PROJECT/TASK DESCRIPTION

A6.1 PURPOSE/BACKGROUND

The SCHD-PCS will create emission inventories to comply with Federal air quality standards 

and U.S. Environmental Protection Agency regulations and which may be used to aid in air 

quality planning, air quality modeling, and in environmental risk assessment. The 

development and use of the emission inventories will improve the ability to plan for good air 

quality.

For AERR reporting (annual and base year):

As required by the AERR, the SCHD-PCS conducts an annual (Type A)/triennial (Type B, 

Title 5, Synthetic Minor) inventory to document air emissions, set permit requirements, and 

provide information to the EPA. The applications for emissions inventory data include use of 

the data in annual trends reports, state implementation plan (SIP) development, compliance 

demonstrations, emissions fees programs, the development of transportation conformity 

emission budgets and in modeling activities designed to evaluate ambient air concentrations 

encountered by the general public. For the SIP program, the air emission inventory is a basis

in the development of air quality control and maintenance strategies. Shelby County 

regulations require point sources to report and certify emissions of air pollution, annually.

Point Sources:

The SCHD-PCS is the lead agency responsible for compiling the point source emissions 

inventory for Shelby County, Tennessee, including identification of sources, documenting 

the method used to calculate emissions from each source, and presenting the findings.

The agency collects emission inventory data via a reporting process that starts with the 

annual inventory survey sent to major and minor point sources for the purpose of emission 
11

fees payment followed by another survey, the Emissions Inventory Questionnaire (EIQ), to 

develop the technical aspects of the emission inventory. Records of permit holders, past 

inventories and other sources of information pertaining to manufacturers in Shelby County

are used to compile lists of sources to be inventoried. Sources of information used to compile 

the lists are provided in Appendix E1.

Once received, agency personnel document receipt of the survey inventories, review and 

analyze the questionnaires for inconsistencies and discuss findings with permit engineers and 

specialists in the agency. Lack of information and/or questionable information is discussed 

with the source prior to final acceptance. The inventory data is then consolidated into the 

database and internal checks are performed to verify its accuracy, completion, and 

consistency with database needs required by the NEI. It should be noted that Federal 

Emission Inventory System (EIS) requirements are reviewed annually and the SCHD-PCS

EIQ and database is then amended to be equivalent to the EIS. Sources not returning the 

questionnaire by specified dates are contacted. Failure to submit the surveys can result in 

enforcement actions. See Section A9 for reference documents pertaining to data quality and 

Section B5 for quality control requirements for point source inventories. The data is then 

entered into the emission inventory system when it’s accuracy has been verified by staff.

The Shelby County stationary point source inventory is the result of efforts to characterize 

pollutant emissions sources since the 1970's. The SCHD-PCS database consists of a large 

number of large (AERR Type A and Type B) and small air emission sources that have been 

compiled since that time. As a result, the database of point sources, above and below an 

actual emission level of 100 tons per year per pollutant, is essentially, if not totally, complete. 

This database provides the foundation of new and future emission inventories developed by 

the SCHD-PCS.

Several methods of source identification are used by the SCHD-PCS to ensure the point 

source inventory remains as complete as possible. The primary data source is the SCHD-PCS

major and minor source permit program, which oversees the registration requirements found 

in the air pollution control codes of Shelby County and the municipalities therein. These 

codes have adopted by reference the State of Tennessee Chapter 1200-3-9, 

CONSTRUCTION AND OPERATING PERMITS. The permit program identifies other 

point sources through annual facility inspections of existing sources, through new source 

review and inspection, and through investigations conducted in response to citizen 

complaints. In addition, sources are found, investigated, and/or added to the source list by 

reviewing commercial news media, trade association memberships, performing area 

surveillance, by referrals from other government agencies, the Chamber of Commerce, and

from source consultants, among possible others.

Following investigation, most of these sources are not considered to be point sources as 

defined for inventory purposes, even though they may require permits. As an example, 

emissions from some sources can be less than one ton per year. However, all sources that are 

permitted by the SCHD-PCS are tracked until notification is received that the equipment or 

emission source has ceased operation. As such, all point source emissions are then subtracted 

from the generated area source category, the remainder of which becomes the “area sources” 

category for Shelby County.

Area Sources:
12

Area sources are required to be included in 3-Year cycle inventories. Methodologies for 

emission estimations are chosen and activity data is gathered for each area source category 

based on the availability of data after all activity data is collected by means of survey,

request, research, or census. Calculations of area source categories are compiled using EPA 

guidance, and after approval by the project manager, are entered into the emission inventory 

data system (Access Database). Area Source Categories inventoried are listed in Appendix 

E3.

On-Road Mobile Sources:

On-road mobile sources are required to be included in 3-Year cycle inventories. On-road 

mobile emissions are prepared by using EPA’s MOBILE6.2 model or MOVES2010 to 

produce emission factors and a local travel-demand model Vehicle Miles Traveled (VMT). 

Data is compiled for EPA in the most current version of the NEI data format.

Non-Road Mobile Sources:

Non-road mobile sources are required to be included in 3-Year cycle inventories. Small 

engine emissions from various categories are calculated using EPA’s NONROAD2008

emissions model. Locomotive emissions are prepared in accordance with methodologies in 

EPA’s Procedures for Emission Inventory Preparation, Volume IV: Mobile Sources. Aircraft 

emissions were calculated using EPA’s EDMS model. Data is compiled for EPA in the most 

current version of the NEI data format.

Biogenic Sources:

Biogenic sources are required to be included in 3-Year cycle inventories. When calculated 

by the SCHD-PCS, biogenic emissions are prepared using the EPA’s Biogenic Emission 

Inventory System (BEIS3.12). Data is compiled for EPA in the most current version of the 

NEI data format. The SCHD-PCS accepts biogenic emissions estimates generated by EPA

but retains the option of generating these emissions in-house.

A6.2 DESCRIPTION OF THE WORK TO BE PERFORMED

1. Point source surveys will provide annual (or seasonal) actual emissions data on a 1-year 

(actual emissions of 100 tons per year and greater) or 3-year (actual emissions less than 

100 tons per year) cycle. Questionnaires are mailed on or about February 1 each year and 

source response is required by April 1. The data is reviewed, corrected where necessary 

and forwarded to EPA on or before December 15.

2. Applicable technical criteria to be used are found in the example instructions and 

screenshots of the EIQ (see Appendices E5 and E6). Section A9 lists all reference 

material.

3. Personnel and equipment requirements: Staff performing data review and analysis are 

professional engineers or have sufficient education/experience to perform emission 

estimation calculations and work with models. The agency has the computer equipment

and software necessary to run the MOBILE6.2, MOVES2010a, NONROAD2008 and 

BEIS3.2 models. Training requirements are outlined in Section A8.

4. The following activities will be utilized for review of data:

• Survey Review
13

• Comparison of like industries

• Checklist Requirements

• Peer Review

• Audit of Coordinates

• Certified Emission Statement Review

• Audit of emission estimate calculations completed before data is forwarded to EPA

• Comparison of Permit Allowables to Emission Inventory Survey

• Comparison of Toxic Release data to data provided in Emission Inventory Survey

5. Schedule of Work:

• Preparation of survey (Mail out survey by February following the year to be surveyed)

• Receipt of survey (April following the surveyed year)

• Internal review (May to December following the surveyed year)

• Preparation of area source inventory (January to November following the surveyed year)

• Approval of inventory (December following the surveyed year)

• Compilation of data in NEI format (as soon as emissions are calculated and verified they are 

placed in NEI Format)

• Submittal to EPA: Emission report to the Region, Electronic Data to the NEI. 

(Emission reports are submitted on or before (December 15) the required reporting date, December 31,

following the surveyed year)

6. Project and Quality Records Required:

• Completed surveys on file

• Completed checklists on file

• Documentation of other data bases used for information on file

• Emission Report to the Region on file

• Correspondence to sources and EPA on file

A7. QUALITY OBJECTIVES AND CRITERIA FOR MEASUREMENT DATA

Emission data collected for reporting to the NEI will encompass industrial air pollution 

sources, area sources, non-road mobile sources, and on-road mobile sources. Emission 

inventories will be entered on an annual basis for Type A point sources and every three years 

(or less) for smaller point sources. Area and mobile source emissions will be submitted in 

lieu of EPA generated emissions every three years or as deemed necessary. The data will 

generally be used as discussed in Section A.5.

Data quality objectives of accuracy, completeness, comparability, and representativeness are 

addressed to ensure an inventory of high quality. The target goals for each objective are listed 

below.

Accuracy: All estimates must be calculated and documented using acceptable methods.

Individual source requirements and availability of data and resources will affect the 

estimation method selection.
14

Completeness: Completeness is addressed by ensuring that all point sources (depending upon 

thresholds) and all applicable area source categories are included in the inventory, and that 

all information required to estimate emissions is present. Applicable area source categories 

are listed in Appendix E3.

Comparability: Data will be compared to the most recent base year inventories depending 

upon the purpose of the project. Generally the base year for the most recent NEI will become 

the previous NEI (i.e, the 2005 for the 2008 NEI). Different base years for various SIPs and 

budgets will be determined depending upon future needs driven by regulatory requirements 

and past accomplishments as warranted. Perceived discrepancies (data outliers) in comparing

one year to another will be corrected or justified.

Representativeness: Actual annual and seasonal daily emissions, as appropriate, will be 

calculated and compared to base year inventories. Local data will be used in inventory 

calculations wherever possible.

A8. SPECIAL TRAINING REQUIREMENTS/CERTIFICATION

All emission inventory quality assurance staff shall have a minimum of a bachelor’s degree 

in engineering or related scientific discipline. These staff members are trained in standard 

emissions estimation methods. The current training requirement is “in house” or on-the-job 

training. Memberships in environmental organizations are voluntary.

A9. DOCUMENTATION AND RECORDS

A9.1 Purpose/Background

Completed point source EIQs, area source, non-road mobile source, and on-road mobile 

source data is retained by the SCHD-PCS. Hard copies of questionnaires and other relevant 

data are kept in files managed by the emission inventory lead engineer. Electronic copies of 

the EIQ and other electronic data are kept on SCHD-PCS computer hard drives and in Shelby 

County Information Technology archives. Backup disks are created to store completed files 

as well. Data is kept for an indefinite period of time and can be found dating back to the 

1970’s.

A9.2 Information Included in the Reporting Packages

Point Source: Electronic files are submitted to EPA through the Exchange Network Web 

Client v2.0 and the EIS Gateway annually and on a three year basis.

Area, & Mobile Sources: Emissions from area, on-road mobile, and non-road mobile 

sources are reported as a Shelby County total. The VOC, NOx, CO, PM10, PM2.5, SO2, and 

ammonia emissions are reported in annual tons per year and in daily tons per average ozone 

season day. In addition, emissions for each category are reported by individual Source 

Classification Code (SCC). For non-road mobile sources the SCCs are combined into classes 

(e.g., lawn and garden equipment, construction equipment) as class totals. Summary tables 

are provided which include major category (point, area, on-road mobile, and non-road 

mobile) totals. Historically, inventories developed for these categories have been used ‘in-
15

house’ and EPA generated inventories for Shelby County have been used in the NEI. The 

option exists for SCHD-PCS to generate and submit these categories for use in the NEI. 

Should this occur, this information will also be submitted to EPA through the Exchange 

Network Web Client v2.0 and the EIS Gateway.

B. MEASUREMENT/DATA ACQUISITION

B5. QUALITY CONTROL REQUIREMENTS

Point Source: The SCHD-PCS maintains a list of all point sources that have received air 

pollution control operating permits. Sources are added to the list as a result of construction 

and operating permit applications, complaints received, surveys performed, media releases 

and referrals from other agencies and the community. This list is maintained and is relied 

upon to actuate Type A and Type B major source lists as the case may be. Once attained, 

these sources are required to provide technical data to better understand and estimate 

emissions and emissions potential. Sources that close are included in the system until such 

time as it is apparent, with certainty, that they will not reopen in the future. Often, closure 

letters are required, where possible, and inspections performed, if needed, to verify such 

events. Existing sources are required by law to verify their annual emissions. File reviews 

and source inspections are conducted annually on major sources and every three years on 

minor sources as a check on the sources status. Enforcement action is taken where needed to 

assure continued compliance with Shelby County regulations.

The SCHD-PCS is authorized to collect air emission inventory information in Shelby County, Tennessee 

pursuant to a number of laws and regulations which are cited in the transmittal letter to the sources . This 

letter can be found in Appendix E4.

Estimation Methods And Data Gathering

Information sources found in A9.3 will be utilized to select estimation methods and gather 

information necessary to develop the inventory. See Appendix E5 and E6 (EIQ instructions 

and EIQ screenshots). QC activities during data gathering include thorough documentation of 

methods and data sources, and checking for reasonableness of data obtained. General 

estimation methods and calculations are discussed in the EIQ instructions. The emissions are 

compared with previous year emissions to detect significant differences.

Missing Data

Missing data will be identified by the inability to complete the calculations. If data are found 

to be missing, a reasonable effort will be made to acquire the data. If this is unsuccessful, 

estimates will be made based on past years' data or default information contained in EPA 

documents and models. Sources of all data are required to be documented.

Application Of Rule Effective And Rule Penetration

Rule effectiveness (RE) reflects the ability of a control device or regulation to achieve all the 

emission reductions that could be achieved by full compliance at all times. Rule penetration 

(RP) is a measure of the extent to which a regulation covers emissions from a source 

category. RE/RP has been the subject of ongoing discussion nationally and is the topic of a 

draft report by the Emissions Inventory Improvement Program (EPA/STAPPA/ALAPCO). 

Briefly, the report recognizes that control efficiencies are often based on in-use conditions, 

and when this is the case, RE has already been taken into account. This is the situation for 

point sources in the NAAs. Additionally, some point source emissions are estimated through 

source testing, and therefore do not use control efficiencies and RE/RP to calculate 

emissions. For area sources, SCHD-PCS will evaluate each control measure to determine 

whether EPA default RE and RP estimates (80% and 100%) should be applied or some more 

representative value used.
17

Corrective Action

Corrective and follow-up actions identified during the inventory development process will be 

noted and referred to the appropriate staff. Both the corrective actions identified and results 

of actions taken in response will be documented and kept on file.

Written documentation specifying inventory methodology and information sources will be 

required.

Area and Mobile Sources: Emissions will be documented in order to trace the sources of the 

methodologies and activity data, including work performed by contractors. Checklists, 

emissions comparison tables, and methodology audits are used in the quality assurance 

process to ensure completeness of data and conformity with methodologies. Peer review of 

contracted and staff generated emissions estimations are conducted by staff. Modeling staff 

reviews the data as well prior to usage. Rule effectiveness and rule penetration are 

incorporated into affected category emissions. Emissions from point sources are subtracted 

where applicable. The emissions are compared with previous year emissions to detect 

significant differences. These significant differences are further reviewed for accuracy. All 

categories are reviewed to determine validity.

In General

• All emission calculations shall be traceable to source reporting or county estimation 

methods.

• Locations of point sources shall be physical addresses; source names shall include the 

corporate name and site.

• All latitudinal and longitudinal coordinates will be verified for accuracy.

• Non-reactive volatile organic compounds will not be included as VOC based upon the 

most recent version of 40 CFR 51.100.

B9. DATA ACQUISITION REQUIREMENTS (NON-DIRECT 

MEASUREMENTS)

Point Source: All point-source data are acquired directly from reporting companies.

Area & Mobile Sources: Area source categories are listed in Appendix E3. Other general 

area categories will be obtained from EPA draft versions of the NEI. Quality control 

requirements described in Section B5 will be applied, which may require replacement or 

elimination of generic data with specific data. Generic data may be replaced with better 

activity or surrogate data. Better activity data consists of the use of the results of surveys of 

categories reporting actual activity data (e.g., fuel use or paint or solvent use), which is used 

in emissions calculations. More appropriate surrogate data may be used (e.g., the actual 

number of employees occupied in an area source business type) to estimate emissions as 

opposed to using the total county population to estimate emissions from that category.

As generic data may be limited in scope or developed for a different domain, data specific to 

Shelby County will be sought out and used whenever available, to include converting state 

and national statistics to county relevant data. Such limitations are noted in national and state 

level data that when apportioned to the county level tend to misstate the impact of the 
18

category. This is readily apparent in aviation, commercial marine, and railroad data for 

Shelby County.

B10. DATA MANAGEMENT

The following information in this section generally describes the efforts taken to collect, 

protect, and report emission inventory data for Shelby County, Tennessee, so that it may be 

used by the EPA, other agencies, and the public, with a high degree of confidence.

Completed point source EIQs, area source, non-road mobile source, and on-road mobile 

source data is retained by the SCHD-PCS. Hard copies of questionnaires and other relevant 

data are kept in files managed by the emission inventory lead engineer. Electronic copies of 

the EIQ and other electronic data are kept on SCHD-PCS computer password protected hard 

drives and in Shelby County Information Technology archives. Backup disks are created to 

store completed files as well. Data is kept for an indefinite period of time and can be found 

dating back to the 1970’s.

Screenshots of the standard EIQ form used for point source submittal can be found in 

Appendix E6. This form is in MS-Excel and therefore the staff has Excel on their computers. 

This data is then transferred into MS-Access which is also available to staff.

The staff also has Internet access to contact companies and to submit data to EPA in the NEI 

format and to the public and other agencies as needed in a readible format. The Bridge tool, 

downloadable from EPA’s site is also used.

In order to process the off road and on road data, both the NONROAD2008 model for 

nonroad mobile and Mobile Vehicle Emission Simulator (MOVES) for mobile source data 

are used.

Locomotive emissions are prepared in accordance with methodologies in EPA’s Procedures 

for Emission Inventory Preparation, Volume IV: Mobile Sources. Aircraft emissions were 

calculated using EPA’s EDMS model. Data is compiled for EPA in the most current version 

of the NEI data format.

Again, screenshots of the electronic EIQ are found in Appendix E6. The EIQ can be used as 

a checklist and as a reporting tool for emissions from point sources that are required to be 

submitted to the SCHD-PCS.

Models for the generation of on-road and non-road mobile will be used as checklists in and 

of themselves. Default values in those models, EDMS, NONROAD2008, and 

MOVES2010a, will be used where applicable, and will be replaced, where appropriate, with 

values specifice to Shelby County, Tennessee.
19

Area source checklists will be developed depending upon the area source category and will 

generally follow guidance found in the Emission Inventory Improvenment Program (EIIP) or 

AP-42, among others.

C. ASSESSMENT/OVERSIGHT

C1. ASSESSMENTS AND RESPONSE ACTIONS

A number of data quality assessments are performed on the data before it is submitted to 

EPA.

Point Source:

When at least 95 percent of the sources in an EIQ cycle have been completed, emission 

inventory team members conduct a quality assurance survey of all data, identifying incorrect 

or suspicious data, including large sources of unspeciated VOCs, suspiciously high annual 

emissions rates, suspiciously high and suspiciously low ozone season emissions rates, 

probable errors in emissions determination methodologies, suspect emission point 

parameters, and incorrect or suspicious Lat/Long coordinates for emission points. By 

comparing the numbers to those in other inventory databases, the team may identify 

discrepancies in the reporting of hazardous air pollutants. Any suspicious or incorrect data 

discovered during this process is investigated and documented.

As a final step in the QA process, the emission inventory team considers each account 

individually, comparing the total account emissions for the current year with those from the 

previous year. Following the completion of the QA process, the emission inventory team 

evaluate the types of errors and their causes, and when appropriate implement guidance for 

QA review to decrease errors discovered during the QA process.

Area and Mobile Sources:

The inventory team conducts audits of newly completed area and mobile emissions 

inventories. Audits are performed comparing two or more inventories for the same year and 

categories to determine the most accurate methodologies being used in development. The 

final inventory will be comprised of data from the audited inventories with the best 

methodologies having been selected on a category-by-category basis. 

The inventory team is responsible for ensuring that updates are made and that correct 

replacement methodologies are implemented. MOVES model input data is carefully audited 

by inventory staff to ensure accuracy of emissions calculations.

C2. REPORTS TO MANAGEMENT

Status and summary of point source accounts and area and mobile source types and levels of 

emissions are reported to the Air Planning Branch Supervisor and the Pollution Control 

Section Technical Manager, among others, upon request.

D. DATA VALIDATION AND USABILITY

D1. Data Review, Validation, and Verification Requirements

The SCHD-PCS will accept, reject, or qualify data in an objective and consistent manner 

depending on the validity and verification of the data source. Stationary point sources, for 
20

instance, must certify their emission levels with the signature of a responsible company 

official (i.e., owner, operator, CEO). Data review is an in-house examination to ensure that 

data have been recorded, transmitted, and processed correctly. That includes, for example, 

checking for data entry, transcription, calculation, and transformation errors.

D2. Validation and Verification Methods

Once input data is gathered, it is used to calculate emissions for on-road, non-road, and area 

sources. For point sources, if the EIQ is found to be complete and acceptable, the stated 

emissions are used as provided. If emissions calculated or received are not comparable with 

similar inventories or seem to have discrepancies, the staff will check and if needed contact 

the data source and correct the errors. The Project Manager will finalize any methods used, 

corrections made, or the acceptance of emissions data.

EIQs are filed and maintained by the SCHD-PCS. They are available to the EPA, and others, 

in toto, where confidential information has been taken into account. Outputs from the onroad and non-road models list the information used to generate the results and are therefore 

available upon request. Area source information is available upon request and will show 

calculations made and assumptions used in generating their results.

D3. Reconciliation with Data Quality Objectives

The SCHD-PCS intends to address, to the extent feasible, NEI requirements which are used 

in the development of emission inventories for NAAQS and hazardous air pollutants. To this 

end, emission inventories developed by the EPA for on-road and non-road mobile and area 

sources are reviewed and considered against inventories generated in like manner by the 

SCHD-PCS and takes into account new EIIP and Office of Transportation Air Quality

guidance. Where anomalies occur, data in-puts of both inventories are studied as to their 

proper relevance and a decision is made to accept one which is deemed more accurate for 

Shelby County. Data specific to Shelby County and the surrounding area is generally 

preferred by the SCHD-PCS to data with a regional or national connotation.

Concerning stationary point sources, requirements of the EPA’s NEI are reviewed annually 

and modifications are then made to the SCHD-PCS Emission Inventory Questionnaire (EIQ) 

so that data obtained from Shelby County point sources are equivalent or equal to data that 

would be required by EPA should EPA conduct such a survey of Shelby County. Stationary 

point sources, in addition to reporting information requested by the EIQ, must certify their 

emission levels with the signature of a responsible company official. In the absence of other 

emission inventories, this certification acts to validate as much as possible the data and the 

calculated emissions sent to EPA for input to the NEI. A newly developed inventory will be 

compared to previously developed inventories to check for completeness and correctness of 

data and for the purpose of discovering changes in emissions that may or may not have been 

discovered in source compliance inspections and file review. These comparisons will take 

into account new EIIP and AP-42 guidance.

Other audits and activities will be conducted as deemed appropriate and include, among other 

things, the following:

Peer Review: An ongoing data review and validation will be conducted by staff, the 

Project Manager and the Quality Assurance Officer before entering emissions and data 

into the SCHD-PCS data system.
21

Independent Audit: Can be conducted by a contractor or by a different agency upon 

request by the EPA.

Survey Check: Once all survey data is collected and emissions are verified for each 

point source, data is input into the SCHD-PCS data system by the project manager who 

insures that each point source is accounted for.

TRI Audit: Project Manager will compare calculated and reported emissions SCHD-PCS 

emissions to recent TRI data and report discrepancies to an SCHD-PCS enforcement 

personnel.

SCHD-PCS data review by EPA: Data submitted to the NEI will be checked by EPA’s 

EIS QA. When corrections and/or changes have been made and all errors removed, the 

data is finalized and input into EPA’s EIA production environment.

Permit Allowables to Actual Emissions Comparison: Project Manager will use MSAccess software to quarry, compare, and maintain a record of allowable to actual 

emissions.

APPENDIX E4: SHELBY COUNTY 2010 EIQ EMAIL LETTER

Dear :

The Shelby County Health Department – Pollution Control Section (SCHD-PCS) is conducting the 

2010 Emissions Inventory Questionnaire (2010 EIQ) of major sources. The goal of the 2010 EIQ is to 

have all major sources update the emissions that were furnished to SCHD-PCS in the 2009 EIQ.

Since we expect this to be fairly simple, facilities are required to submit their completed 2010 EIQ to 

the SCHD-PCS by close of business on December 22, 2011.

To accomplish this task, SCHD-PCS has attached to this e-mail a MS-Excel workbook loaded with 

the emissions data provided for your facility in the 2009 Emissions Inventory Questionnaire (2009 

EIQ). Each workbook contains 4 spreadsheets as follows:

• General Plant Information Form

Note: data reported in the 2009 EIQ is provided on this form, please update where necessary.

• Emissions Form

Note: data reported in the 2009 EIQ is provided on this form, please update where necessary.

• New Emission Sources Form

Note: input the requested data to this form only if you are reporting emissions on the 

Emissions Form from an emissions source that was not reported in the 2009 EIQ. 

Otherwise, no input is required.

• Emissions Data Certification Form. 

Note: verify that the emissions totals indicated on these forms are correct then have it signed 

by a responsible official (i.e. the owner, or the operator).

SCHD-PCS is authorized to collect air emission inventory information in Shelby County, Tennessee 

pursuant to the following:

1. Sections 110 (a) (2) (F) (ii) and 112 (s) (1) (2) (3) (4) of the Federal Clean Air Act

2. Sections 68-201-105 and 68-201-115 of the Tennessee Code Annotated

3. Section 14.5-30 of the Shelby County Code

4. Section 16-98 of the City of Memphis Code

5. Similar sections for each of the other incorporated areas in Shelby County, Tennessee

When returned, the 2010 EIQ should include:

1. hardcopy of your facility’s emissions

2. electronic copy of your facility’s emissions, and

3. a cover letter. 

a. a breakdown of each air pollutant in tons per year (TPY).

b. an explanation of significant increases or decreases in emissions

c. information on the addition of new Groups and Process Unit

d. information on Groups/Process Units to be deleted and the reasons for the deletions

If the emissions from your facility have not changed from the 2009 EIQ, simply provide a cover 

letter to SCHD-PCS that includes a statement to that effect and it will be used for your 2010 

emissions. No other information will be needed.

Finally, notice that the 2010 EIQ Packet has a .piz file extension. Save this file to your hard drive and 

rename .piz to .zip. Be sure to keep copies of all forms, calculations, and information used to determine 

the emissions stated in your facility’s EIQ. For additional assistance, please contact the Emission 

Inventory Staff at (901) 222-9571.

Introduction

The Pollution Control Section of the Memphis and Shelby County Health Department (SCHD-PCS) is required by 

federal law to collect detailed information from facilities located in Shelby County, Tennessee that emit 

contaminants to the atmosphere on actual annual emissions for calendar year 2010. Each facility receiving this 

emission inventory package is required to complete and return it by September 19, 2011. When returned, the 

Emissions Inventory Questionnaire (EIQ) should contain the following:

 All of the requested data forms and any supporting documentation and calculations

 Examples of calculations used to determine the emissions stated in the Emission Inventory forms 

 Actual annual emissions of all pollutants of interest (see topic “Reporting Emissions Estimates”)

 Material throughputs for annual and seasonal rates

 Fuel parameters of heat content, % ash, and % sulfur

 Operating parameters for effective Start and End dates and times

 Emission release point parameters of height, diameter, exit gas temperature, velocity, and flow rate

 Name and description of pollution control equipment in use

 SIC number(s), NAICS number(s), SCC number(s), and any MACT Codes that apply

The primary objectives of the EIQ are:

 To collect and maintain data in a standard format

 To ensure the data meets the requirements of the Federal Clean Air Act 

 To ensure the use of the most current emissions determination methods 

SCHD-PCS is authorized to collect air emission inventory information in Shelby County, Tennessee pursuant to the 

following:

1. Sections 110 (a) (2) (F) (ii) and 112 (s) (1) (2) (3) (4) of the Federal Clean Air Act

2. Sections 68-201-105 and 68-201-115 of the Tennessee Code Annotated

3. Section 14.5-30 of the Shelby County Code

4. Section 16-98 of the City of Memphis Code

5. Similar sections for each of the other incorporated areas in Shelby County, Tennessee

The information provided will be used to assist SCHD-PCS to track emission trends affecting Shelby County.

Be sure to keep copies of all forms, calculations, and information used to determine the emissions stated in your 

facility’s EIQ. Thank you for your help in this matter. For additional assistance, please contact Christopher Boyd at 

(901) 222-9571.

I. Getting Started

1. How to Open the Questionnaire

a. Instructions for Microsoft Office 1997, 2000, and 2003 users

To open the Emission Inventory Questionnaire (EIQ) spreadsheet application, Microsoft Office 1997, 2000, and 2003 

users must ensure that the Microsoft Excel security setting allows macros to be enabled. To adjust the security 

settings you must open the Security dialog box. This is done following these 3 steps:

1. Select Tools from the toolbar

2. Select Macro from the dropdown menu

3. Select Security from the dropdown menu

Figure 2a illustrates how to select the Security Panel from the list of options on the MS Excel menu bar.

Figure 2a: Select Tools > Macro > Security

Figure 2b displays the Security Level dialog form with the (3) security settings for macros. This spreadsheet 

application will not operate if the Security Level is set on “High”. The only choices that will allow the spreadsheet 

application to function are either “Medium” or “Low” (be sure to select “OK” otherwise this modification will not take 

effect).

Figure 2b: The MS Excel Security Panel

Remember, only two of the security settings, either low or medium, will permit the EIQ spreadsheet application to 

operate.

The following three bullets describe how each setting affects the behavior of macros.

 "High" is the highest level of security. It automatically disables all unsigned macros. This setting will not allow 

the EIQ spreadsheet application to function properly. It will prevent the EIQ spreadsheet application from 

opening. If your Microsoft Excel security setting is set to “High” it must be adjusted downward.

30

 "Medium" is the midrange level of security. It displays a warning window stating the dangers of opening 

documents containing Macros and will allow you to make the decision whether to enable 

 or disable the macros. You must choose “enable macros”. Doing so will allow the EIQ spreadsheet 

application to function properly. WHEN YOU HAVE COMPLETED YOUR EIQ, YOU MUST RESET 

YOUR SECURITY SETTINGS TO THEIR PREVIOUS CONDITION AT ONCE IN ORDER TO PROTECT 

YOUR COMPUTER OR SYSTEM FROM MACROS THAT MAY HAVE VIRUSES.

 "Low" is the lowest level of security. It allows all macros to run. This setting will allow the EIQ spreadsheet 

application to function properly. WHEN YOU HAVE COMPLETED YOUR EIQ, YOU MUST RESET 

YOUR SECURITY SETTINGS TO THEIR PREVIOUS CONDITION AT ONCE IN ORDER TO PROTECT 

YOUR COMPUTER OR SYSTEM FROM MACROS THAT MAY HAVE VIRUSES.

b. Instructions for Microsoft Office 2007 users

To open the Emission Inventory Questionnaire (EIQ) spreadsheet application, Microsoft Office 2007 users must ensure 

that the Microsoft Excel security settings allow macros to be enabled. To adjust the security settings, locate the 

“Security Warning” message bar and left-click on the button labeled “Options” (see Figure 3a). This will display the 

“Microsoft Office Security Options” userform. Proper operation of this 

Figure 3a: the “Security Warning” message bar

gather production rate information. This might be in the form of the amount of fuel burned, cubic yards of concrete 

produced, or pounds of solvent used, etc. Remember, only report emissions from equipment operated in 2010.

2. How to Complete the 2010 Emission Inventory Questionnaire (EIQ)

STEP 1: Table 3 displays a list of the EIQ forms. Included in it are brief remarks for each form. Pay particular attention 

to these remarks because they indicate the specific form that each source type is responsible for completing. If your 

facility is a Minor Source you must complete only the “General Plant Information Form” and the “Emission Data 

Certification Form”. Otherwise, if your facility is a Major or Synthetic Minor Source you must complete all of the 

EIQ forms with the exception of the Control Equipment Form, which is required only when there are devices employed 

to control air contaminants.

regulated. These substances are carcinogens, mutagens, or reproductive toxins, and they are produced by certain "sourcespecific" industries. "Major" sources of HAPs are defined as sources that emit 10 tons or more per year of any single 

HAP or 25 tons or more per year of a mixture of HAPs. "Area" sources are smaller facilities that release lesser quantities 

of toxic pollutants into the air. Area sources are defined as sources that emit less than 10 tons per year of a single air 

toxic, or less than 25 tons per year of a combination of air toxics. Each MACT standard establishes its own compliance 

date. The MACT compliance date is usually but not always three years after the promulgation of the MACT standard. In

ACTUAL THROUGHPUT NUMERIC VALUE - As the START DATE and END DATE of the Emission Period 

Form designates the emissions time period, the ACTUAL THROUGHPUT NUMERIC VALUE field on the Emission 

Period Form should be reported as the activity value for the same time period delineated by the Start and End Dates. The 

ACTUAL THROUGHPUT NUMERIC VALUE data reported here should be the annual total for the year taking into 

account the various reporting periods as discussed in I. 9. Identification Numbers (IDs), Their Use and Retirement on 

pages 6 and 7.

When reporting ACTUAL THROUGHPUT NUMERIC VALUE, the following unit codes must also be reported: UNIT 

of MEASURE, MATERIAL, and MATERIAL I/O.

16
42

The values reported for the three throughput unit fields should match the values reported for the associated unit fields for 

Emission Factor Numeric Value on the Emissions Form. 

For example, if the ACTUAL THROUGHPUT unit fields reported on the Emission Period Form are as follows:

UNITS of MEASURE = TON;

MATERIAL = Coal;

MATERIAL I/O = I

Then the EMISSION FACTOR unit fields reported on the Emission Form should be as follows:

EMISSION FACTOR NUMERIC VALUE = numeric value 

EMISSION FACTOR UNIT NUMERATOR = LB;

EMISSION FACTOR UNIT DENOMINATOR = TON;

MATERIAL = Coal; and

MATERIAL I/O = I (for Input)

And the unit code values reported for the EMISSION FACTOR on the Emission Form should be as follows:

FACTOR UNIT NUMERATOR = LB;

FACTOR UNIT DENOMINATOR = EACH-YR;

MATERIAL = Employee (or Person); and

MATERIAL I/O = E (existing).

Operating Schedule Parameters may be reported for a facility that differ from the annual average operating schedule 

parameters reported for the facility on the Emission Process (EP) record. For example, a facility normally operates 7 

days per week and 24 hours per day, but during the summer months (e.g., June through August) only operates 5 days per 

week and 16 hours per day. The value of 7 days per week and 24 hours per day should be reported in Annual Average 

Days per Week and Annual Average Hours per Day fields on the Emission Process Form. The seasonal operating 

schedule of 5 days per week and 16 hours per day should be reported in the Period Days per Week and Period Hours per 

Day fields on the PE Record, and should also designate the Start Date and End Date for the seasonal period.

How to Enter Seasonal Throughput for Total Annual Emissions

Providing the seasonal throughput percentages with process schedule data and the total annual emissions is a good 

way to provide air quality modelers with information needed to determine average day emissions for a specific season of 

interest. Thus, the Preferred Reporting Method is as follows:

Form Data Element Entry Value

Emission Period START DATE YYYY0101 (YYYY = calendar year, i.e. 2010)

END DATE YYYY1231

ACTUAL THROUGHPUT Specify the total activity for the year 

Material is the material used that created the pollutants at each process. Depending on the type of source category, 

material may refer to the type of fuel combusted, raw material processed, product manufactured, or material handled or 

processed.

Material I/O - Indicate whether the material above was consumed or used (I), produced (O), or existed (E).

Supplemental Information for the Emission Process Form

The following information is for specific data elements in the Emission Process Form and is provided in addition to the 

Emission Process Form data dictionary. This information will assist you in correctly implementing the noted fields.

PROCESS MACT CODE - Major/Area source classification under the CAAA Sections 112 & 129. A 

Maximum Achievable Control Technology (MACT) Code is a 4-digit code assigned to all MACT categories and 

sub-categories. The MACT code should be reported for all relevant facilities at the process (SCC) level within a 

MACT category. If MACT codes are not reported, SCHD-PCS will make default assignments. More information on 

the MACT source categories and the MACT program is located at www.epa.gov/ttn/uatw/eparules.html. Should you 

need assistance call (901) 544- Select to open the Menu which will show links to other forms, websites and a variety 

of information needed to submit the emission inventory.

PROCESS MACT COMPLIANCE STATUS provides information on the controls that are in place due to Sections 

112 & 129 of the Clean Air Act Amendments (CAAA). Codes are provided for the following:

• Major Sources that are listed under Sections 112 & 129 for which:

 the compliance date has not yet occurred; source is assumed major (>10/25 tons per year) and will be 

subject to standards under Sections 112 & 129, Code value = 01;

 Compliance date has occurred; source is classified major because emission levels are >10/25 tons per 

year as of initial compliance date, even if emission levels are <10/25 tpy at a later date, Code value = 02.

• Area Sources (<10/25 tpy) that are listed under Sections 112 & 129, and:

 Are subject to Section 112 or 129 standards as regulated area source category, Code value = 03;

 Are not subject to Section 112 or 129 standards as a synthetic minor source (regulated major source 

category and the source has reduced emissions below major source status before initial compliance date), Code 

value = 04;

 Are not subject to Section 112 or 129 standards as a true area or natural minor source, Code value = 

05.

As annual throughput is reported on the Emission Period Form, the seasonal activity percentages and average annual 

operating data must be reported on the Emission Process Form in order to enable SCHD-PCS, EPA, or other NEI users, 

to disaggregate the reported annual activity and emissions to seasonal activity and emissions and compute emissions for 

an average season day.

19
45

How to Enter Seasonal Throughput for Total Annual Emissions

Providing the seasonal throughput percentages with process schedule data and the total annual emissions is a good 

way to provide air quality modelers with information needed to determine average day emissions for a specific season of 

interest. Thus, the preferred reporting method is as follows:

Form Data Element Entry Value

Emission Process WINTER THROUGHPUT PCT Whole number between 0 and 100

SPRING THROUGHPUT PCT Whole number between 0 and 100

SUMMER THROUGHPUT PCT Whole number between 0 and 100

FALL THROUGHPUT PCT Whole number between 0 and 100

ANNUAL AVG DAYS PER WEEK Whole number between 1 and 7

WEEKS PER YEAR Whole number between 1 and 52

5. Emission Release Point Form Instructions

Sample Emission Release Point Form

The Emission Release Point Form reports emission point information for your facility. An “emission release point” is 

defined as a stack, pipe, vent, or opening through which a significant percentage of emissions (from one or more 

processes) are released into the atmosphere (with or without a control device). The physical attributes and the location 

coordinates of the emission release point must be reported to identify where emissions are released to the ambient air 

whether by a stack or non-stack (e.g., fugitive release). If a non-stack release, coordinates may be reported for the 

general location of the emission release point. The height, diameter, longitude and latitude, exit temperature, exit 

velocity, and gas flow rate must be provided when completing this form. Use the instructions below to complete the 

Emission Release Point Form.

Please note the following helps

Command Buttons:

MENU - Select to open the Menu which will show links to other forms, websites and a variety of information 

needed to submit the emission inventory.

PREVIOUS - Select to open the Emission Unit Form.

NEXT - This selection will open the Emission Form for a Major or Synthetic Minor Source.

the Emission Period Form.

Item 2 - Emission Release Point Type Code: Left double-click in the cell to initiate a code search. Then follow the 

instructions provided by the onscreen dialog boxes. Select the Emission Release Point Type code that best applies to 

your facility from the codes retrieved by the code search. For more information see the topic below entitled, “Emission 

Release Point Type”.

Item 3 - Emission Release Point Height: Left double-click and enter the Emission Release Point height (in units of 

feet). Note that the Emission Release Point height is the distance above ground to the discharge point. Thus, for an 

emission release point located on the roof of a building, the height equals the sum of the height of the building plus the 

length of the Emission Release Point. For example, the Emission Release Point height of a 10-foot Emission Release 

Point atop of a 30-foot building is 40 feet.

Item 4 - Emission Release Point Diameter: Left double-click and enter the Emission Release Point Diameter (in feet). 

The Emission Release Point Diameter is the inside measurement of the stack at the discharge point. If the Emission 

Release Point Diameter is not circular, calculate the equivalent diameter (De) using, De = 2(H * W)/(H + W). 

Where H is the height and W is the width of the cross sectional area of the flow.

Note: This field is equipped with an Equivalent Diameter Calculator. To access it:

• right-click Emission Release Point Diameter data field

• enter the height (H) and the width (W) into the appropriate input box

23
49

• select “Calculate Equivalent Diameter” to calculate the equivalent diameter using the equation given above

• select “Enter Value”

Item 5 - Emission Release Point Fenceline Distance: Left double-click and enter the distance from fenceline to the 

facility in feet (ft).

Item 6 - Exit Gas Temperature: Left double-click and enter the temperature of the exit gas (in degrees Fahrenheit --

°F). Note, quantify the amount, DO NOT enter “Ambient” in this field.

Item 7 - Exit Gas Velocity: Left double-click and enter the velocity of the exit gas (in feet per second -- ft/s).

Item 8 - Exit Gas Flow Rate (a calculated field): the flow rate of the exit gas stream is automatically calculated. 

However, this calculation is only performed when data has been input to the Stack Diameter field and then the Exit Gas 

Velocity field. The flow rate at actual exhaust gas temperature and normal atmospheric pressure is determined and the 

value is expressed in units of actual cubic feet per second (ACFS). The following equation is used,

ACFS = SCFS x (Ta + 460)/(Ts + 460)

Where;

Ta = actual exhaust gas temperature (degrees F)

Ts = temperature at standard conditions (normally 70 degrees F)

Should you need assistance call (901) 222-9571.

Item 9 - X Coordinate (Longitude): Left double-click and enter the longitude coordinate in decimal degrees. This is 

a negative data point for N. America. Include (-) sign. Example: the longitude for the Memphis and Shelby County 

Health Department is -90.03315 degrees. For more information see the topic below entitled, “X and Y Coordinates”.

Item 10 - Y Coordinate (Latitude): Left double-click and enter the latitude coordinate in decimal degrees. This is a 

positive data point for N. America. Include (+) sign. Example: the latitude for the Memphis and Shelby County Health 

Department is +35.14354. For more information see the topic below entitled, “X and Y Coordinates”.

Item 11 - Horizontal Fugitive Emissions Area: Left double-click and enter the horizontal area of the fugitive 

emissions in square feet (ft2

). For more information see the topic below entitled, “Emission Release Point Type”.

Item 12 - Fugitive Emissions Height: Left double-click and enter the release height above the terrain of the fugitive 

emissions in feet (ft). For more information see the topic below entitled, “Emission Release Point Type”.

Item 13 - Emission Release Point/Name Description: Left double-click and enter a description for the equipment or 

process served by the Emission Release Point(s).

Supplemental Information for the Emission Release Point Form

The following information is for specific data elements in the Emission Release Point Form and is provided in 

addition to the Emission Release Point Form data dictionary. This information will assist you in correctly 

implementing the noted fields.

Special Command Button: The Equivalent Diameter Information command button is located on the Emission 

Inventory Toolbar. When selected this button will provide a brief overview on how to calculate the equivalent diameter 

of a non-circular area. In addition, it provides instructions on how to start the Equivalent Diameter Calculator, which is 

launched by right-clicking in the “Diameter” data field. From that point, the equivalent diameter can be calculated by 

supplying the height and width of the cross sectional area of the flow.

Reporting a Single Process that Goes to Multiple Stacks

A very typical scenario is that one emission process vents to one emission release point. In some instances however, one 

emission process may vent to several emission release points. In that case, create and report a ‘dummy’ PROCESS ID 

for each additional EMISSION RELEASE POINT ID. Split the PROCESS ID (and therefore emissions) and create the 

necessary number of (unique) PROCESS IDs to match the respective number of emission release points.

24
50

Example (Record ID)

SITE EMISSION UNIT EMISSION PROCESS EMISSION RELEASE POINT

(SITE ID) (EU ID) (PROCESS ID) (ERP ID)

01 B 1 1

01 C 1A 1

01 C 1B 2

01 C 2 2

01 C 3 2

Note: Emission Unit ‘C’ has a process segment 1 that emits through stacks 1 and 2. In this case, Process 1 is divided into 

PROCESS 1A and PROCESS 1B, creating two unique processes, one for each stack.

X and Y Coordinates reported as Latitude and Longitude must be reported in decimal degrees. If you need assistance 

obtaining the latitude and longitude of your facility, please refer to “18. How to Find the Latitude and Longitude 

Coordinates for your facility on the Internet”(located on page 9). If you need to convert latitude and longitude 

coordinates in degrees, minutes, and seconds to decimal degrees, a conversion tool can be accessed at 

http://www.fcc.gov/mb/audio/bickel/DDDMMSS-decimal.html.

Emission Release Point Type

When reporting Emission Release Point Type Code = 02, 03, 04, or 05 (all are stack descriptions), physical stack 

parameters apply and should be reported. Those data elements are: STACK HEIGHT, STACK DIAMETER, STACK 

(base/centerline) to FENCELINE DISTANCE, EXIT GAS VELOCITY, EXIT GAS TEMPERATURE, and EXIT GAS 

FLOW RATE.

When reporting Emission Release Point Type Code = 01 (fugitive) or 06 (downward-facing vent), then the stack 

parameters (listed above) do not apply. However, HORIZONTAL AREA FUGITIVE, RELEASE HEIGHT FUGITIVE, 

and FUGITIVE DIMENSIONS UNIT must be reported. These dimensional data are used in emission estimation models 

to predict ambient concentrations of fugitive emissions.

Equivalent Diameter for Non-circular Emission Release Points:

 De = 1.1 28 HxW

 Where: H is the height of the cross-sectional area in feet (ft)

 W is the width of the cross-sectional area in feet (ft)

Temperature Conversions:

• Fahrenheit (οF) to Celsius (οC): [ 32] 9

5 °C = °F −

• Kelvin (K) to Celsius (οC): °C = K − 273.15

Exit Velocity of Emission Release Points:

 A

Q V =

 Where: V is the gas exit velocity in feet per second (ft/s)

 Q is the volumetric flow rate in cubic feet per sec (ft3

Supplemental Information for the Control Equipment Form

The following information is for specific data elements in the Control Equipment Form and is provided in addition to the 

Control Equipment Form data dictionary. This information will assist you in correctly implementing the noted fields.

Capture Efficiency (%) means the weight per unit time of a pollutant entering a capture system and being delivered to a 

control device divided by the weight per unit time of the total pollutant generated by the source of the pollutant, expressed as 

a percentage. The capture system includes, but is not limited to, hoods, ducts, fans, booths, ovens, dryers, etc., that contain, 

collect, and transport an air pollutant to a control device. For emission sources such as combustion devices where the 

exhaust system is integral to the equipment, the capture efficiency is 100%.

Total Capture/Control Efficiency (%) is the collective percent efficiency value for all control devices reported, 

including system percent capture efficiency if known. This field is only applicable when there are device types reported 

in addition to a primary control device. The capture efficiency must be input if total capture/control efficiency is input. If 

unknown, consult the supplier of the equipment

When One Control Device Serves Multiple Process Segments

If one control device serves multiple processes, create a Control Equipment record for every process that is controlled, 

e.g., duplicate the control equipment record for each unique process that shares the control device. In this scenario, the 

control equipment percentage reported on duplicate control equipment records should be the same unless the control 

equipment percentage varies by the pollutant being controlled.

Example: Emission Processes 1 and 2 are vented to the same control device, with PRIMARY CONTROL EFFICIENCY 

equal to 85%.

Record No. Record Type Key Data

1 Emission Process Process ID = 1

2 Emission Process Process ID = 2

3 Control Equipment Process ID = 1 Primary Control Efficiency = 0.85

Common Pollution Control Device Efficiencies

In most cases, the control efficiencies for air pollution control devices that are commonly employed throughout 

industry can be obtained by consulting the Emission Inventory Improvement Program (EIIP), Volume II, Chapter 

12, entitled “How to Incorporate Effects of Air Pollution Control Device Efficiencies and Malfunctions into 

Emission Inventory Estimates”. This is an EPA publication that can be obtained at 

www.epa.gov/ttn/chief/eiip/techreport/volume02/ii12.pdf. A copy of this publication will be available to reference in 

our office from 8:00am – 4:30pm Monday through Friday (except on holidays). If this publication does not include 

the control efficiency information for the control equipment installed at your facility then you should request that the 

equipment manufacturer or supplier provide it to you. For more information please contact us at (901) 222-9571

retrieve the numeric quantities of each pollutant reported on the “Emission Form”. As you can see in the screenshot 

above, the “Criteria Pollutants” section of this column does not require any data entry because the criteria pollutants are 

already listed in spaces 1-9. Hence, nothing is required of Major and Synthetic Minor Sources in this section.

On the other hand, to locate and retrieve the numeric quantities of each pollutant reported on the “Emission Form” for 

the “Other Pollutants” and “Hazardous Air Pollutants” sections, Major and Synthetic Minor Sources must enter the 

Chemical Abstract System numbers (CAS#) into the appropriate spaces provided in this column (note: CAS# should 

only be entered one time exactly as it appears on the “Emission Form”). Specifically, all non-HAPs must be entered in 

the “Other Pollutants” section in spaces 10a through 10k. And all HAPs must be entered in the “Hazardous Air 

Pollutants” section in spaces 11a through 11an on page 1 of this form and in spaces 11ao through 11ci on page 2 of this 

form. Once all CAS#s have been entered, the total amount for each pollutant reported on the “Emission Form” will 

automatically be entered in both the “Annual Emissions” columns and the “Total Emissions” columns.

Minor Sources need not do anything for 1 through 9 because this information has already been entered. However, in

both the “Other Pollutants” and “Hazardous Air Pollutants” sections the pollutant CAS# must be entered next to the 

alphabetic characters in spaces 10 and 11. Again, use space 10 for non-HAPs and use 11 exclusively for HAPs. 

Item 2 - (Major & Synthetic Minor Sources Only) Annual Emissions: Major and Synthetic Minor Sources that have 

utilized the electronic format to report emissions activity in this questionnaire will find that this information has been 

auto-filled for the criteria pollutants. However, for the non-HAPs and HAPs the CAS#s must entered in the appropriate 

spaces.

Item 3 - (Minor Sources Only) Annual Emissions: Left double-click and enter the annual emission amounts for each 

pollutant. Express criteria pollutant amounts in tons and hazardous pollutant amounts in pounds.

Item 4 - Accidental Releases: Left double-click and enter information pertaining to accidental releases. Express 

criteria pollutant amounts in tons and hazardous pollutant amounts in pounds.

Item 5 – Total Emissions: No input is required here, however, if CAS#s has not been entered for the non-HAPs and the 

HAPs, totals will not appear. This spreadsheet application will automatically sum the pollutant totals. Please make sure 

that you have expressed the criteria pollutant in tons and the hazardous and other air pollutants in pounds. Please verify 

the accuracy of the totals.

Item 6 - Total Emissions for which Emissions fee has been paid: Left double-click and enter the emissions amounts 

for each pollutant that you paid emissions fees for in your 2010 Emissions Fees Bill. 

Item 7 - Does this report contain confidential information?: Please respond Yes or No. Express criteria pollutant 

amounts in tons and hazardous pollutant amounts in pounds.

Item 8 - Source Number: No input is required here. A default value has been selected based upon the Source Number 

entered on the General Plant Information Form.

Item 9 - Company Name: No input is required here. A default value has been selected based upon the Company Name 

entered on the General Plant Information Form.

Item 10 - Please Print Your Name Here: Left double-click and enter the name of the responsible company official 

here.

Item 11 - Please Sign Your Name Here: The “Emissions Data Certification Form” must be signed by an official 

responsible for attesting to the accuracy of the emission inventory data. This form must be printed, signed and returned 

with the emission inventory data.

Item 12 - Date: Enter the date.
