### Background

The purpose of this memorandum is to document and update the methods used to

estimate capital and annualized costs for reducin g hazardous air pollutant (HAP) emissions and

volatile organic compounds (VOC) from marine tank vessel loading operations (MTVLO) for

gasoline. 1 

### All cost estimates are based on the applic ation of an add-on control device to reduce

emissions. Potential control options and natio nwide impacts for add-on controls for MTVLO

facilities are presented.

II. 

### Total Capital Investment

Based on information obtained from one vendor, lean oil absorption systems are available

for control of hazardous air pollutants (HAP) and volatile organic compounds (VOC) emitted

during loading of gasoline to marine vessels. 2 

### The equipment cost is based on a typical unit cost

of $650,000 for a lean oil absorption system for a throughput of 5,000 gal/min associated with

barge loading of gasoline and a typical unit cost of $1,200,000 for a lean oil absorption system

for 15,000 gal/min associated with ship loading. The total capital invest ment (TCI) required was

estimated using EPA standard costing procedures . First, the purchased equipment cost (PEC)

was estimated by multiplying the vendor equipmen t costs by a factor of 1.08. The PEC includes

costs for auxiliary equipment, instrumentation, sa les, freight, etc. The TCI was then estimated

by multiplying the PEC by a factor of 1.15 to c over the installation co sts (i.e., foundation and

supports, handling and erection, piping, electrical, in stallation, engineering, construction, startup,

### and performance tests). Thus, the TCI was es timated to be 1.24 times the vendor equipment

costs.

For a typical MTVLO facil ity, the TCI ranged from $807,000 for barge loading to

$1,490,000 for ship loading. These values were base d on the vendor costs. The TCI for typical

MTVLO facilities is shown in Table 1. Ba sed on public comments on the October 21, 2010

proposal, commenters indicated that costs were significantl y higher for offshore loading

terminals and ranged from 1.3 to 2.3 times the costs for a typical MTVLO facility. 3

, 4 

### The

equipment costs were assumed to be approximate ly 2.3 times higher than the costs for a typical

MTVLO facility. 5 

### For offshore loading terminals, the TCI ranges from $1,860,000 for barge

loading to $3,430,000 for ship load ing. The TCI for offshore load ing facilities is shown in

Table 2. Additional details on the TCI calculations are shown in Attachment A.

For comparison with a lean oil absorption system, capital costs for a refrigerated

condenser unit were estimated. Capital costs for lean oil absorption systems were roughly

comparable to costs for refrigerated gasoline va por recovery systems of similar capacity. Costs

for refrigerated gasoline vapor recovery sy stems were based on the OAQPS Control Cost

Manual, 6 

### escalated to 2010. The total capital inve stment of a refrigerated gasoline vapor

recovery system with a capacity of 5,000 ga l/min was estimated at $1,020,000 (2009$). The

total capital investment for a refrigerated gaso line vapor recovery syst em with capacity of

15,000 gal/min was estimated to be $1,870,000 for ship loading at a typical MTVLO. These

costs are within approximately 25 percent of a similarly sized lean oi l absorption system for

either barge loading or ship loading.

III. 

### Total Annual Costs

Annualized costs for the lean oil absorption system were developed based on information

provided by the vendor and EPA sta ndard costing procedures. The lean oil absorption system is

estimated to have a variable operating cost of $0.006 per gallon loaded, and the vendor indicated

that essentially all of this cost is attri butable to electricity. The labor costs for

running/maintaining the control device system were estimated based on an estimated labor

### EPA received comments on the 1995 MTVLO NESHAP on the cost to control vapor emissions from offshore

loading facilities. In general, commenters cited that offshore loading costs would range from 2 to 5 times the costs

for typical MTVLO. One commenter that provided specific cost information at that time noted that TCI costs were

2 times the cost for a typical MTVLO. (See Federal Standards for Marine Tank Vessel Loading Operations and

National Emission Standards for Hazardous Air Pollutants for Marine Tank Vessel Loading Operations, Technical

### requirement of 1.5 hr/day and an assumed labor rate of $25.76/hr and an estimated maintenance

labor requirement of 1.5 hr/day and an assumed labor rate of $26.48/hr (these rates were loaded

with benefits and overhead). 7 

### The maintenance parts cost was estimated to be 1.0 times the

maintenance labor costs. Indirect annual costs included administrative charges, property tax, and

insurance at 4 percent of the TC I, and the capital recovery based on a capital recovery factor of

0.1424 (interest rate of 7 percent for an equipm ent life of 10 years). The assumptions for

estimating the annual costs are provided in Table 3.

Control options were developed based on annual gasoline throughput cutoffs, with a

control efficiency requirement or total organic carbon concentration limit for MTVLO that

exceed the threshold. Model MTVLO were considered for gasoline throughputs of 1,000,000

bbl/yr, 5,000,000 bbl/yr, and 7,000,000 bbl/yr. Th e TAC is dependent on the gasoline

throughput, since the variable operating cost is based on throughput. The TAC for each gasoline

throughput model, for both barges and ships at a typical MTVLO f acility, is shown in Table 1.

TAC for both barges and ships at offshore loadin g facilities is shown in Table 2. Additional

details on TAC calculations are shown in Attachment A.

IV. 

### Emission Reductions for Model MTVLO

The emissions and the emission reductions were estimated for barge and ship loading for

each gasoline throughput model. The VOC emissions from barge loading of gasoline are

assumed to be 3.4 pounds of VOC per 1,000 ga llons gasoline loaded (lb VOC/1,000 gal). 8 

### The

VOC emissions from ship loading of gasoline are assumed to be 1.8 lb VOC/1,000 gal. 5 

### The

HAP content of the VOC is assumed to be 5.0 percent by weight. 9 

### The overall recovery rate for

the lean oil absorption system is assumed to be 99 percent. The emissions reductions for VOC

and HAP for each model are shown in Tables 1 and 2.

Because the lean oil absorption system rec overs gasoline product, a product recovery

credit was included in the cost analysis. The va lue of the recovered product was assumed to be

$560/ton, which partially offsets the operating cost. The TAC considering the recovered

gasoline, is shown in Tables 1 and 2 for barges and ships, for each gasoline throughput model.

VI. Secondary Impacts Estimates for Controlling MTVLO for Gasoline Loading

The operation of lean oil absorption systems ha s an impact on electricity consumption. It

is estimated, based on information from the vendor , that the lean oil absorption systems consume

approximately 0.1 kWhr/gallon of gasoline loaded. Thus, electrical consum ption associated with

a 1,000,000 bbl/yr applicability th reshold would be approximately 9.3 million kWhr/yr on

average per facility. The elec trical consumption associated with a 7,000,000 bbl/y r applicability

threshold would be 29 million kWhr/yr on averag e per facility. These impacts and secondary

emissions for SO 2
