SOURCE DESCRIPTION

The Tn-Cities Landfill (TCL) is a closed municipal solid waste treatment and disposal facility owned and operated bythe Salt River Pima Maricopa Indian Community (SRPMIC)

The facility is located in Section 34, Township 2 North, Range 5 East, of the Gila and Salt River Baseline and Meridian,

Maricopa County, Arizona. The mailing address of the landfill is Route 1, Box 216, Scottsdale, Arizona 85256.

The TCL site occupies approximately 217 acres and is bounded by State Road 87 on the north, the Salt River on the

south, the Union Rock and Materials Corporation aggregate processing plant to the southwest and open land to theeast. The TCL accepted residential and commercial wastes from 1972 to October 9, 1993. Waste types included

household waste, landscape and other types of green wastes, inert soil, asphalt, commercial construction and

demolition materials, and concrete.

A Site Diagram of the TCL is included as Figure 1SITE CHARACTERISITCS

The TCL was designed using cut and fill methods. Excavated soils were used for daily, intermediate, and final cover.As indicated in the Initial Design Capacity Report and Tier 1 Non-Methane Organic Compound (NMOC) Emission Rate

Report submitted to the EPA on April 6, 2000, the site’s design capacity exceeds the threshold of 2.5 million mega

grams (Mg). Based on the design capacity and the results of the Tier 1 NMOC emission rate, which demonstrated anannual rate exceeding 50 Mg per year for the current year, a landfill Gas Collection and Control System (GCCS) is

required to be installed to fulfill the requirements of the New Source Performance Standards (NSPS).

Gas Collection and Control System

Tn-Cities Landfill has installed a landfill gas (LFG) collection and control system. The current LFG collection and

control system includes 108 vertical extraction wells, lateral and header piping, and a candlestick flare operating

continuously. The GCCS removes landfill gas under a vacuum from the landfill mass. The system collects andcontrols migration surface and subsurface gases from the disposal area.

Tn-Cities Landfill Energy FacilityA portion of the collectable LFG is piped to the Tn-Cities Landfill Energy Facility, owned and operated by Salt River

Project (Permit No

Tn-Cities Landfill Title V Permit Renewal Application

The following is a list of emission sources applicable to this Title V Permit Application.

Description

Non-Fugitive Sources

• The facility has an active 2,500 cfm John Zinc candlestick flare utilized for control and combustion of the

landfill gases generated by the landfill mass. The flare generates combustion emissions.

• Landfills produce surface emissions of non-methane organic compounds (NMOCs), volatile organic

compounds (VOC5), and hazardous air pollutants (HAP5) which are generated by the microbial degradation of

buried refuse. Based on the estimated 2004 LFG generation rate and reported actual flow rates, the implied

collection efficiency is 53%.

Fugitive Sources

• Landfill gas emissions containing non-methane organic compounds (NMOCs), volatile organic compounds

(VOCs), and hazardous air pollutants (HAP5) are generated by the microbial degradation of buried refuse.

The fugitive portion of the landfill gas is estimated to be 47% of the total LFG produced.

• Paved/unpaved roadways used by maintenance vehicles generate fugitive particulate (PM) dust emissions.

However, these emissions are considered to be insignificant for Title V Permitting purposes based on the

emission rates pursuant to Part 71 §71.5(c)(11)(ii)(A) and (B).

No other non-trivial activities conducted in the operations and maintenance of the TCL is expected to impact and/or

cause potential emissions of regulated air pollutants.

METHODOLOGY FOR EMISSION CALCULATIONS

Attachments B and C contain the assumptions, methodologies, conversions, and calculations on which the Title V

permit application is based. Provided below is a discussion of the methodology used to estimate actual and potential

emissions of the emission units located at the TCL.

The landfill gas (LFG) estimates were based on the landfill design capacity and historical refuse disposal rates. The

PTE estimates for the LOG is a conservative estimate, utilizing the “peak” year pursuant to the EPA’s Landfills GasEmission Model (LANDGEM). Because the landfill is now closed, the peak year is the current year. Therefore, actual

and PTE emission estimates are analogous.

Slight numerical differences in calculation results may be created due to spreadsheet rounding errors.
Tn-Cities Landfill Title V Permit Renewal Application

estimated historic disposal rates. The estimated NMOC concentration in LFG also was taken from AP-42’s

recommended default value for MSW landfills (595 ppmv).

The Tn-Cities Landfill was opened in 1973 and accepted waste from 1973 through 1993. The total volume of wastein-place was estimated to be approximately 11.5 million tons based on the disposal history provided by SRP. Becausethe landfill is a closed site, the “peak” year for potential to emit (PTE) estimates is 2004. Calculations for actual and

PTE emissions from LFG are based on 2004 estimations utilizing EPA’s LANDGEM.

EPA’s LANDGEM model results using the estimated disposal history, k, Lo, and NMOC values described above are

shown in Attachment C. As shown in the backup calculations, total LFG generation from the landfill in 2004 is

estimated to be 1,921 SCFM, total methane generation is estimated to be 1,010 million m3 per year, and total NMOC

generation is estimated to be 66 tons (60 Mg). Based on the estimated 2004 LFG Generation rate and the reported

actual flow rates, the implied collection efficiency is 53%.

HAPs/Criteria Pollutants

As noted above, concentrations of NMOCs were taken from AP-42 Table 2.4-2 default value. VOC concentrations areassumed to be 39% of the NMOC concentrations, based on Note C of AP-42 Table 2.4-2. Concentrations of HAPs

present in LFG at the Tn-Cities Landfill were taken from the values reported in a recent Waste Industry Air Coalition

(WIAC) study of the constituents in LFG (“Waste Industry Air Coalition Comparison of Recent Landfill Gas Analyses

with Historic AP-42 Values”). Specifically, the WIAC-1 values listed in Table 2 of that report are used. The WIAC

report and an accompanying memorandum are included in Attachment H of this application. For HAP compoundsnot listed in the WIAC report, AP-42 Table 2.4-1 (“Default Concentrations for LGF Constituents) and Section 2.4-4 are

used. The total estimated emissions of HAPs, VOCs, and NMOCs were estimated using the total LFG flow rate (for

average of PTE conditions) and the molecular weights and estimated average concentrations of each compound.

Flare Emissions

As mentioned previously, a majority of the LFG collected at the Tn-Cities Landfill is combusted in the five IC engines

operated by the Salt River Project. Emissions from the engines are covered under a separate Title V application.

Collected LFG that is not combusted in the engines is routed to a utility flare. Calculation of emissions from the utility

flare is included in this Title V application.

Flare Emission estimates are the total emissions generated by the landfill multiplied by the percent LFG flow to the

flare and the flare destruction efficiencies. Emissions of HAPs and NMOCs\VOC5 from the flare are based on

compound-specific destruction efficiencies provided in AP-42 Table 2.4-3, and the LFG flow rate to the flare.

Emissions of CO and NOx are based on manufacturer provided date. Emissions of the remaining pollutants from the

flare are based on the LFG flow rate to the flare and AP-42 emission factors for PM and Sox.
