## 1 MEMORANDUM

TO: Amy Hambrick, U.S. EPA, Sector Policies and Programs Division/Natural Resources and Commerce Group

FROM: Amber Allen and Roy Oommen, Eastern Research Group, Inc.

DATE: June 2010

SUBJECT: Facility, Unit, and Emissions Test Da tabase for the Sewage Sludge Incineration Source Category

1.0 INTRODUCTION

This memorandum summarizes the information collection activities and data standardization procedures used to develop the Sewage Sludge Incinerators (SSI) facility, unit, and emissions test database. 1 

## The database discussed in th is memorandum reflects the data utilized in preparation of the proposed regulations. The EPA rece ived additional data after the preliminary data analysis, but due to the court- ordered deadline, did not have sufficient time to review and evaluate the additional data and revise the analyses. EPA intends to review the additional data submitted from a quality assurance and completeness perspective and incorporate that data into the final standards, as appropriate. To the extent the Agency receives additional emissions data during the comment period, the Agency will assess that data as it develops the final emission standards.

Section 2.0 summarizes the data collecti on efforts and Section 3.0 discusses the procedures used to reconcile dup licates and standardize the repor ted data. Appendix A contains a lists and brief descriptions of the tables and fields contained in the SSI database. Appendix B provides a table showing the data conversi ons used to standardize emission units.

2.0 DATA COLLECTION
The initial inventory of SSI units operating in the United States is described in a separate memorandum. 2 

## In October of 2009, EPA issued an Info rmation Collection Request (contained in Docket ID EPA-HQ-OAR-2009-0559) to 9 companies ow ning 10 of the facilities listed in the inventory. These 10 facilities collectively opera te 20 SSI units and were chosen because their units had the most efficient control devices in th e inventory. The ICR consisted of two parts: the first was a survey to collect comprehensive data on the operation of each SSI unit at each facility, and the second was a test plan to collect emission s data from each facility. The survey requested that facilities provide informa tion concerning any operating SSI units (e.g., location of unit, contact person, emissions, fuel type, pollution cont rols, and operational co sts). Facilities were also asked to submit to EPA any relevant test data from the last 5 years. Data from this part of the ICR were reviewed and combined with the SSI inventory data as a first step in the development of an SSI emissions database. The second part of the SSI ICR asked facilities to conduct emission tests for pollutants where emissi ons data were missing from the test data

## 2 submitted in the first part of the ICR. Faciliti es submitted emissions test reports using various means, including hard copies of stack test reports and EPA’s Electronic Reporting Tool (ERT). Survey respondents submitted data for a total of 16 SSI units. A second source of emissions information was test reports collected from St ate environmental agencies’ public databases for nine multiple hearth units at 6 facilities. The emission tests in these reports were conducted between 2000 and 2009. One additional piece of information, needed to determine whether facilities were small entities, was facility population data. The collect ion of this data is described in more detail in the SSI inventory memorandum. 2



## Table 1, in Appendix A, lists the names of the tables within the SSI Database and describes the sources of the data they contain. Tables can be divided into primary data, used directly in determining emission limits, em ission reductions, and cost estimates, and supplementary data, comprising data provided thr ough ICR survey responses not used directly in these analyses. Additionally, look-up tables were created to list control abbreviations, criteria pollutants, and other useful information for the an alysis. Fields within each table and associated descriptions are listed in Tabl es 2a -2d for primary data a nd Tables 3a-3k for supplementary data. A working table, called “Baseline and Cost Inputs” was also created. This table initially contained only known values for all parameters used to calculate cost s and emissions. Several steps were then taken to fill data gaps using s ubcategory averages, flow rate factors, and other assumptions. The fields of this table and how they were used in subsequent analyses are described in further detail in Section 3.3 of this memo.

3.0 DATA STANDARDIZATION PROCEDURES
3.1. Survey Data Because the ICR survey was formatted as a questionnaire rather than a series of spreadsheets, the information reported had to be tr ansposed to a spreadsheet in order to be used effectively in a database. Fields were create d as needed to accommodate the information presented, and data was modified as appropriate in order to be used in calculations for all subsequent data analyses. For instance, in some cases, facilities returned one survey for multiple units, yielding responses that needed to be separa ted by unit. Text-heavy res ponses that didn’t fit specifically into one field were often included in a ‘Note’ or ‘Details’ field within the database. Units of measure were converted to be consistent with all other re ported units of measure before entering into the database. Several examples of how pieces of data we re transferred to the database are presented below. Steps such as thes e were taken wherever necessary in the database development process.

but currently limited to 1,814 lbs/hr by SCDHEC Converted 1,814 lb/hr to 22 dry tons per day (all other facilities provided tons per day) and entered as current maximum capacity. Noted original capacity in ‘Note’ field.


## Types of control devices used with each SSI unit were previously included in the inventory database 2 

## , but detailed control information was pr ovided in response to the ICR survey as well. To merge the data consistently in the Un it table, two fields were created: one descriptive field to merge the names of all controls listed in both the inventory data and the surveys, and one concise field abbreviating the controls and in corporating each unit into a control category representing a specific combinati on of controls. For instance, inst ead of associating a unit with a “dry cyclone scrubber, venturi quench followed by impingement tray scrubber, and internal afterburner prior to dry cyclon e” throughout the analysis, a unit would be assigned the control category “abo - cs - vs - imp.” This allowed the un its to more easily be grouped by their controls devices. See Table 4a for a list of control abbreviations.

3.2 Emissions Test Data Most of the fields presented in the Emissions table of the database were taken directly from ERT files as populated by the respondent. Ho wever, additional data fields such as ‘Notes’ and ‘Calculation Notes’ were added to the data base to accommodate additional data extracted from submitted test reports. To track where the data originated, a ‘DataSource’ field was also added.
Emissions data from the ERT was already report ed in the units of measure desired for the analyses, so no further standardization was necessary for this data. However, not all test reports received reported data consiste ntly; consequently, units of m easure were converted to units consistent with the ERT data before importing test report data to the data base. The data reported by facilities were converted into the following st andardized units of measure (see Appendix B for data conversion equations):

## 4  Parts per million by volume on a dry basis, corrected to 7 percent oxygen (ppmvd @ 7% O 2 

## ) for hydrogen chloride (HCl), hydrogen fluoride (HF), sulfur dioxide (SO 2 

## ), carbon monoxide (CO), and nitrogen oxides (NOx);

 Milligrams per dry standard c ubic meter, corrected to 7% O 2 

## (mg/dscm @ 7% O 2 

## ) for metals (including cadmium (Cd), mercur y (Hg), and lead (Pb)), condensable particulate matter (PM), filterable PM; PM 10 

## ; PM 2.5 

## ; total PM (including condensables);

 Nanograms per dry standard cubi c meter, corrected to 7% O 2 

## (ng/dscm @ 7% O 2 

## ) for dioxin/furans (both totals a nd specific congeners); and

 Percent (%) for opacity.

 Dry tons per hour (dtph) for sludge feed rate.

 Dry standard cubic feet per minute (dscfm) for stack gas flow rate.

In order to analyze the emissions data on a pollutant-by-pollutant basis, pollutant names needed to be standardized as well. Table 4b s hows the reported pollutant name (‘Pollutant’) and what standardized pollutant names were chos en (‘CommonName’). Names in the Emissions table were updated to the common names listed in the look-up table.
3.3 Preparing for Data Analysis

In order to perform cost and emission re duction analyses for the MACT floor limits, actual or estimated values need to be obtained for each unit in the inve ntory for the following parameters:

1. Unit Sludge Capacity (for cost algor ithms and to estimate unknown feed rates) 2. Operational Hours (for co st algorithms, baseline emissions, and emission reductions) 3. Average Dry Sludge Feed Rate (for cost algorithms and to estimate flow rates) 4. Average Flue Gas Flow Rate (for cost algorithms, baseline emissions, and emission reductions) 5. Average PM concentrations (for fabric filter costs) 6. Annual Unit Operating Cost (for de termining alternative disposal costs) 7. Tipping Fee (for determining alternative disposal costs)

Average feed rates and flow rates can be calculated for all units for which test data is available. Emissions data used for developing th e proposed standards consist of test data for 25 units at 15 facilities. There are therefore data ga ps in flow rate and feed rate for the other 193 units in the inventory. Note that not all units have test data for every criteria pollutant, so there are more data gaps for the average pollutant concentration.

## 5 The table ‘Baseline and Cost Inputs’ was crea ted as a working table in which calculations could be performed in order to fill these data gaps. Values for data gaps were estimated as follows for the above parameters:

1. Unit Sludge Capacity:
As described in the inve ntory database memorandum 2 

## , some data gaps were filled with capacities obtained through stat e permit information or through web searches of unit owner or operator web sites. This data, comb ined with the survey data, yielded capacity values for 105 units. These are listed in th e field ‘KnownCapacity(dtph)’. The capacities for the remaining 113 units were filled in us ing the subcategory averages of the known capacities (2.26 dry tons per hour for fluidized bed (FB) units and 2.69 dry tons per hour for multiple hearth (MH) units). Final capacities used for all subsequent analyses are listed in the field ‘Capacity (dtph).’

2. Operational Hours:
As described in the baseline emissions memo 3 

## , it was assumed that facilities with only one SSI unit would be operating the unit the entire year (8,400 hours assuming 2 weeks downtime). Facilities with two units w ould be operating one unit one year and the second unit the next, averaging to 4,200 hours for each if normalized to a yearly basis. Facilities with even numbers of units followed this assumption. Facilities with three units were assumed to be operating two units the majority of the year (8,400 hours) and one unit would be a backup and operate 360 hours (assuming operation during 2 weeks downtime for other units). The operational hours obtained from these assumptions and used in all subsequent analyses, are listed in the field ‘OperationalHours.’ 3. Average Sludge Feed Rate: Feed rates were averaged for each unit having test data. Of the 193 remaining units, 80 units had known capacities associated with them. A utilization factor of 75% was applied to these capacities to obtain a feed rate for these units. The resulting feed rates and average feed rates from test data are listed , in dry tons per hour, in the ‘KnownFeedRate’ field. The feed rates for the remaining 113 units were filled in using the subcategory averages of the feed rates from the test da ta (1.69 dtph for FB units and 2.02 dtph for MH units). Final feed rates used for all subseque nt analyses are listed in the field ‘Feedrate dtph.’ 4. Average Flue Gas Flow Rate: Flow rates were averaged for each unit having te st data. These averages are listed in the field ‘KnownFlowRate.’As noted in baseline emissions memorandum 3 

## , the flue gas flow rate exiting the SSI units where data were not available was calculated by using a flow rate factor relating flue gas flow rate to the dry tons of sludge fired in the incinerator. An average flue gas flow rate factor from all the test data was calculated for each subcategory (5,455.7 dscfm/dry tons per hour of sludge for FB units and 9,642.5 dscfm/dry tons per hour of sludge for MH units) and then multiplied by the average sludge feed rates. Final flow rates used for a ll subsequent analyses are listed in the field ‘Flow Rate dscfm.’

## 6 5. Average PM Concentration: The process by which average pollutant concen trations were determined for all units is described in the baseline emissions memorandum. 3 

## For the fabric filter cost algorithm, PM concentrations were required as inputs, and units needed to be in grains per dry standard cubic feet rather than mg/dscm. Concentrations were converted using the corresponding equation in Appendix B and ar e listed in the fiel d ‘PM (gr/dscf).’ 6. Annual Unit Operating Cost: The cost to operate each SSI unit needed to be estimated in order to determine the costs associated with facilities that would choose to shut down thei r units and divert their waste to landfills. As described in a separate memorandum 4 

## , the annual costs for some units were provided in the SSI survey responses . These values are listed in the field ‘KnownTAC.’ Cost factors were determined, in dollars per ton, for these units. Average and minimum cost factors for each subcategory were applied to all other units to estimate annual costs to operate all other units. F actors and resulting co sts using these two scenarios are listed in the fields ‘TAC factor (avg)($/dry ton)’, ‘TAC (avg)’, ‘TAC factor (low)($/dry ton)’, and ‘TAC (low).’ 7. Tipping Fees: Tipping fees used in the landfill cost algorithms are described in detail in a separate memorandum. 4 

## They are listed in the ‘TippingFee’ field of the Baseline and Cost Inputs table.
