### The purpose ofthis document is to provide documentation for the calculation of impacts from the control ofVolatile Hazardous Air 

### Pollutant (VHAP) emissions from equipment leaks. The document is 

### designed to be used with 

### aLotus 1·2·3 

### for Windows program. Both the program and this document are based on previous work done on calculating the impacts for control of\'HAP 

### from equipment leaks for the Hazardous Organic NESHAP (HON). The equations used in 

### the spreadsheet are based on the same costing equations and assumptions used in 

### the development ofHON impacts. nus was 

### done in 

### order to assure common basis 

### for comparing estimated HON equipment leak costs to costs calculated by 

### projects using this document and its associated spreadsheet The equations used in 

### the spreadsheet and this document are based on a memorandum from RadiID Corporation to 

### David Markwordt onJune S, 

### 1991. The memorandum is titled Impacts from the Control ofVHAP Emissions from Equipment Leaks in 

### Non-SOCMI Process Units for HON. The memorandum may be

• 2.0 CALC1JLAnON OF COSTS 

### The methodology for calculating equipment leak impacts is based on three steps. The steps used are as follows:

• Step 1. 

### Use Section 114 letters to collect actual equipment leak count data from facilities, or**d~velop estim~tes**  

### ofequipment leak counts by other

. methods. One posslble method is to select the appropriate HON model plants provided in 

### the spreadsheet as a rough representation ofthe industry you are developing impacts for. Step 2, 

### Determine current level ofcontrol for the facilities (i.e. no control. 

## eTa level of**contro~** 

### or MACT level ofcontrol). This may done through the use ofsection 114 information. or a review ofState Rules. Step 3, 

### Based on information from the first two steps, control costs, baseline emissions, and emissioDS reductioDS, are estimated using equipment leak count based algorithms which were developed for the evaluation ofSOCMI precesses. The algorithms are built into the equipment leaks costing softwue contained in 

### a Lotus Spreadsheet The cost methodology including the assumptions for equipment costs, labor rates etc. are presented in section 2.1. The data is presented primarily 

### in tabular format Appendix 1 presents all 

### costing equations and emissions calculation equations used within the software. 2.1 COST METHODOLOGY 

### All costs calculated within the equipment leaks software are based on annualized 1989 dollars. This is 

### done 

### in order to provide acommon baseline for comparing the estimated impacts for standards using this 

### software with the estimated impacts from imposition ofthe HON. Costs for reducing emissiODS 

### from compressoD, open-ended lines, sampling connections. aDd 

### pressure reliefdevices are developed assuming control equipment will 

### be installed. Cosu for 

## reducina emissions from pumps, valves, and connectors are developed assumjng emissions will be 

### reduced through work practices. The general methodology is to 

### determine bue costs for the control ofemissions for each type 

### of equipment. The base costs 

### per component are then used with plant equipment counts to develop capital and annual costs for the control ofemissions from equipment leaks for each plant

2·2

,I

### Table 2-1 presented on the next page presents the cost associated with 

### the purchase and installation ofspecified equipment for the control of

## voe emissions from compressor seals, open-ended lines, sampling connections, and pressure reliefdevices. The base costs presented were taken directly from the Hazardous Organic NESHAP. All 

### cost estimates are based on July 1989 dollars using the ratio ofthe CE Plant Cost Indices. Table 2-2 shows the assumed cost inputs such as labor, monitoringi'requency, initial leak 

### frequency, etc. While Table 2-3 shows the derivation ofannual cost for such factors as the capital recovety cost, annual maintenance cost, annual operating cost, ete. The tables are intended to provide only a briefoverview ofassumed cost factors used in 

### the calculation ofequipment leaks for more detailed information on the cost methodology please read chapter 3: Hazardous Air

### To calculate the cost for a facility you must first input the number ofequipment components into the table provided in the equipment sheet Table 4 lists the inputs that should be 

### provided for each column in 

### the equipment sheet. If

### there are no pieces of equipment for a given equipment type 

### then the input space should be left blank.

/Facili Location State Current Control Level Pump Seals Com ressor Seals Flan es Valves

For the Cost Estimates sheet no input is required. However, for every line that you have inputed equipment a facility the costing equations must be copied to using the copy and paste buttons on the gray tool bar. First push the copy buttoD, then select the lines for which you want to calculate costs for a facility entered on the equipment page. Once this has been done 

### simply push the paste button to paste the costing equations into the selected rows. Model Plant data 

### is set up to be copied direttly into the equipment leaks page. The data is in the same format as the 

### data on the equipment leaks page, you can use the following directions to copy 

### the model plants: highlight the model plantyou wish to copy, then select 

### edit and 

### copy from the 

### top menu, next simply go to the first column on the equipmentpage 

### into which you 

### wish to paste the data and select edit and then paste 

### from the main menu. 3.1 DEFAULT INPUTS The default inputs 

### in the spreadsheet are those inputs that allow the user to change some ofthe underlying costing assumptions used in spreadsheet algorithms. These assumptions are the emission factors, the recovery credit value, and

### th~**frequ~ncy** of

. equipment monitoring. The assumed values may be changed by selectIng the informanon page and then pushing the emission factocs, recovery credit. or**moni~ring ~e~uency**  \...- buttons. The emissions factors are used in the calculation ofthe baseline emlSSlOns and
3·7the eso.mated erruss10ns reduction due to unposition of \{..o\CT controls. Changmg the emissions factors will affect the calculated net annual cost and the COSt effect1 veness. The recovery credit is simply the value of the chemical feedstock or product prevented from released to atmosphere due to imposition ofcontrols. The recovery credit is calculaled by calculating the value ofa megagram ofrecovered product. Due to a unique mix ofcherrucals controUed by eacb standard a new recovery credit should be calculated for each standard. finally the rnon.itoring frequency is the frequency that valves, pumps, compressor seals, and pressure reliefdevices. Cbanging the monitoring requencing affects the operating costs (i.e. reducing the frequencing lowers the cost, wbile raising the frequency increases the cost.), The default inputs are based on values used and documented in the HON. 

### lli emjssjon factors and monitorina frequency values should oot be chanied unless you have developed adequate documentation to support your changes. The default vaules for emission factors are presented in Table 3·1 and the default monitoring frequencies are presented in Table 3·2, The def.ult recovery credit value is based on the value calcul.ted for the HON. Since, the value ofchemicals recovered will be different for e.ch standard a new value should 

### be calculated for each standard. TABLE 3 2 DEFAULT BASELINE EMISSION FACTORS
