Gila River Indian Community (GRIC) TIP Development 

Generally Applicable Individual Source Requirements 

Technical Support Document 

MARCH 9,2001 VERSION 

Section VI. D. - VOC Requirements 

1.0 Introduction & Source ~escri~tion'~ 

The generally applicable individual source requirements for volatile organic compounds (VOC) 

are intended to cover several subcategories of VOC emitting sources including solvent metal 

cleaningldegreasing, surface and architectural coating, as well as storage and transfer of volatile 

liquids. General operating practices for all VOC sources are also included in the regulation. 

There are numerous VOC emitting sources located on GRIC land that will be covered by this 

regulation. Currently, most of these sources fall under solvent metal cleaningldegreasing. The 

pollutant regulated by this portion of the TIP is VOC, although trace amounts of hazardous or 

toxic air pollutants may also be emitted, however these emissions are not covered by this 

regulation. 

Solvent degreasing (or solvent cleaning) is the process of using organic solvents to remove 

grease, oils, wax, or soil from various metal, glass, or plastic items. Many facilities on GRIC 

land conduct some sort of solvent cleaningldegreasing. The majority of these operations are 

small, simple, batch-type cleaners. Emissions from such sources are small, and these sources are 

mainly controlled by proper work practices. Larger, or more complex, degreasers have higher 

emissions and are therefore often required to apply some sort of controls to limit VOC emissions. 

Surface coating is the application of decorative or protective materials in liquid or powder form 

to substrates. Coatings normally include general solvent type paints, varnishes, lacquers, and 

water thinned paints. Surface coating operations include "industrial" and "nonindustrial" 

applications. Industrial coating applications are those associated with a manufacturing operation, 

such as can or other metal coating. Nonindustrial applications include surface coating of 

architectwai structures and automobile refinishing. Architectural structures can include both 

industridcommercial structures and nonindustrial structures. VOC emissions from surface 

coating are mainly dependent on the VOC content of the coating and the method of application. 

Storage and handling of volatile liquids also covers a broad range of sources on GRZC land. 

Volatile liquids include chemicals used in various types of manufacturing, as well as some 

petroleum products. The loading or transfer of volatile liquids includes activities such as 

unloading from a delivery vessel into a stationary storage tank and loading tanker trucks or 

railcars fiom storage vessels at a facility. VOC emissions fiom these sources depend on the 

liquid involved (e.g., its vapor pressure), the storage container, and how the volatile liquid is 

handled during loadinglunloading and disposal.

2.0 GRIC Source Profde 

The majority of the VOC emitting sources on GIUC land have relatively low emissions. Most 

sources will be covered under the general work practice standards for degreasers and proper 

storage and handling of volatile liquids. The potential exists for future facilities in this source 

category locating on GRIC land. Thus, the regulation was developed to encompass future 

sources as well. 

3.0 Technical Review - Emission Units, Pollutants, and Control Technologies 

3.1 Emissions and Controls 

Emissions from VOC operations depend on the VOC content of the substance, the operating 

practices implemented during the storage, handling, usage, and disposal of the substance, and 

any potential controls. Emissions fiom the individual categories covered by this regulation also 

depend on other factors, such as the application method for surface coating and the amount of 

solvent canyout for degreasing. There are typically three methods to control VOC emissions 

from VOC sources: 1) use of a lower VOC-containing material, 2) process changes and 

improved work practices, and 3) add-on control devices. 

For the sources covered by this regulation, VOC emissions are generated mostly due to 

evaporation, thus proper work practices are critical to preventing unnecessary emissions. When 

a reduction in emissions is required, usually the use of lower VOC-containing materials and/or 

work practice changes are attempted first. If this approach is not possible or additional emission 

reductions are required, the application of a system to capture the exhaust in conjunction with 

add-on controls (e.g., carbon adsorption units or condensers) becomes necessary.

4.0 Regulatory Review and Proposed Rule Derivation 

4.1 Tribal Prograrns/Rules 

A comprehensive review of U.S. tribal air quality programs was performed to define the baseline 

of existing tribal rules and source specific standards. The summary findings of this review are 

contained in a separate report. Where tribal rules and standards were identified that were 

applicable to GRIC source categories or met GRIC regulatory objectives, those provisions and 

requirements are detailed herein. 

No tribal programs or rules were identified that pertain to the VOC operations covered in this 

proposed ordinance. 

4.2 Federal Programs and Regulations 

The U.S. Environmental Protection Agency @PA) has developed several Control Technique 

Guidelines (CTG) for source types covered by this regulation (various surface coating operations 

and solvent metal cleaning). These documents discuss how VOCs are emitted and recommend 

controls to reduce emissions depending on the source type. For example, surface coating 

operations are controlled primarily by limits on the VOC content. Many State regulations are 

based on the guidance provided in the CTGs. Consequently, while the individual types of 

surface coating operations covered in State regulations may seem arbitrary, they follow directly 

fkom the categories covered by the CTGs. 

Several New Source Performance Standards (NSPS) and one National Emission Standard for 

Hazardous Air Pollutants (NESHAP) were identified as potentially applicable to the VOC source 

category. . The NSPS cover storage vessels and several types of surface coating (e.g., metal 

fhiture, beverage cans, metal coils). There are three NSPS subparts that cover storage vessels, 

which are broken out by the type of liquid stored and encompass a specific range of dates for 

applicability. The earlier two subparts (Subparts K and Ka) cover only petroleum liquids, while 

the most recent subpart (Subpart Kb) covers the broader category of volatile organic liquids, 

which includes petroleum liquids. Due to the limitations on applicability of the earlier two 

subparts, only the requirements of Subpart Kb are summarized in this TSD. 

Currently, no surface coating operations on GRIC land are covered by the specific NSPS 

subparts for surface coating. Also, there is one facility on GRIC land with a vapor degreaser 

using trichloroethylene, but it is not a major source of HAPS (i.e., emissions are less than 10 tpy 

for a single HAP and less than 25 tpy for total combined HAPS), so NESHAP Subpart T (for 

Halogenated Solvent Cleaning) is not applicable. Thus, the requirements contained in the NSPS 

subparts covering surface coating operations and the halogenated solvent cleaning NESHAP are 

not summarized as part of this TSD.

4.3 State/Regional/Local Regulations 

To define State, regional, and local air quality rules applicable to the source categories present or 

expected to potentially site on GRIC land, representative U.S. State air quality rules were 

screened using Internet resources. This screening identified each State air quality rule set with 

source specific regulations matching the matrix of GRIC source categories. The summary State 

rule screening file, STATEMATRKxls, is included in Appendix A of this document. From 

this, specific rule provisions applicable to the general VOC source category, including emission 

limitations, standards, monitoring, recordkeeping and reporting were documented to form a 

baseline of analogous State rules. Because of the broad representation of State/Local rules 

affecting VOC sources, only a subset of programs were reviewed. 

State/RegionaULocal rules were selected for consideration in TIP development based on 

stringency, technical merit (e.g., work practice standards, control options), presentation, and 

enforceability considerations. The following State/Regional/Local programs were reviewed:

4.4 Analysis of Source Category Emission Limitations and Standards 

4.4.1 Summary and Analysis of Identified Rules/Standards 

In order to evaluate the range of existing tribal, federal, state, and local air quality standards 

relevant to the VOC source categories and make GRIC TIP recommendations, the available data 

set was condensed and organized by emission source. Tables 4-1 through 4-5 provide a 

summary of selected existing standards for the VOC source categories. The tables are organized 

by type of activity as follows:

Table 4-1 General VOC Operations 

Table 4-2 Solvent Cleaning 

Table 4-3 Surface Coating 

Table 4-4 Architectural Coating 

Table 4-5 VOC Storage, Transfer, and Disposal 

Table 4-1 contains a summary of regulations applicable to general VOC sources. This category 

is designed to be applicable to sources not covered under specific source category requirements 

elsewhere in the regulation. General VOC operations cover requirements for VOC that are more 

general in nature (i.e., not associated with a specific activity like degreasing or surface coating). 

These usually include an emission threshold in lb/day or an annual limit. Sources with emissions 

above the threshold are required to reduce their emissions by using lower VOC-containing 

materials, improved work practices, andlor add-on air pollution control devices.

General VOC TSD-030901 Created on 31910 1 7 
Tables 4-2 through 4-5 summarize the regulatory requirements for the source specific categories. 

They are organized by sub-category with the State regulations listed first alphabetically, 

followed by Maricopa and Pinal Counties as well as the California districts, as applicable. 

General operating requirements (e.g., using closed containers to reduce evaporation) are common 

to various activities using VOCs. In most State rules these provisions are often repeated in each 

individual regulation for the different source types (e.g., solvent cleaning and surface coating). 

The requirements are included with the specific source categories in Tables 4-2 through 4-5, but 

to avoid redundancy the proposed VOC regulation will have these requirements as a separate 

section applicable to all VOC sources. 

Table 4-2 summarizes the requirements for solvent cleaning. The types of solvent cleaning 

operations covered in most State regulations are based on those covered in the solvent metal 

cleaning (degreasing) CTG. These include cold cleaners, open top vapor degreasers, and 

conveyorized parts cleaners. Emission controls in the CTG encompass equipment specifications, 

including the use of some control devices, as well as work practice requirements. The State 

regtllations are similar, although some go beyond the requirements in the CTG. Table 4-2 uses 

Delaware Regulation 24, Section 33 (Solvent Metal Cleaning) and the CTG as a "baseline," and 

then highlights individual components of other StateAd regulations that go beyond this 

baseline. 

The application of surface coatings is broken into two categories -- industrial-type surface 

coating and architectural coating. Both of these source types are usually regulated by a VOC 

content for the material being applied, but they encompass a different subset of materials. In 

order to facilitate comparison among the regulations, industrial-type surface coating 

requirements are provided in Table 4-3 and architectural coating requirements are presented 

separately in Table 4-4. 

Table 4-5 includes requirements for the storage, transfer, and disposal of VOCs. This covers the 

type of storage container as well as methods used when loading and unloading materials 

containing VOCs. Also included in several regulations are provisions covering the disposal of 

VOCs. One of the primary methods for VOCs to be emitted is through evaporation and these 

requirements are aimed at reducing emissions through proper disposal techniques.

The next table contains the regulations used to develop the provisions for surface coating 

operations. Limited surface coating is conducted on GRIC land currently and an increase in 

activity is not anticipated in the fbture. As mentioned previously, there are numerous NSPS that 

cover surface coating operations and the NSPS will be adopted by reference in the GRIC rules. 

Due to the lack of current activity, the individual NSPS requirements are not summarized here. 

Instead, the proposed ordinance will be based on requirements in the EPA's Control Technique 

Guidelines (CTGs) for various types of surface coating. These guidelines are considered 

Reasonably Available Control Technology (Ib4CT) and most State regulations are based on this 

guidance. In some instances the NSPS are more stringent or cover source types not covered by 

the CTGs. Thus, if a new source locates on GRIC land, its VOC emissions would be subject to 

an NSPS (and the general requirements in this ordinance) that will be protective of air quality.

4.4.2 Derivation of Proposed GRIC Source Category Limits/Standards 

The derivation of the VOC rule provisions was as follows: 

There is some variability between State regulations covering VOC source categories, however, 

most State regulations are quite consistent, with the California districts typically being the most 

stringent. For those source categories for which CTG documents exist, most State regulations 

are based on these provisions. Due to this similar approach nationally, decisions on what to 

include in the proposed ordinance were made mostly based on clarity of the regulatory language 

and the ease of understanding. The requirements are kept consistent with the Maricopa andfor 

Pinal County regulations, as appropriate. The basis for each section is discussed fiuther below. 

Section 1.0 - General Limitations and Standards 

Several State regulations include a generic VOC rule that is designed to cover those VOCemitting processes not specifically regulated in other sections of their regulations. Table 4-1 

includes examples of the requirements contained in several of these regulations, including those 

for Maricopa and Pinal Couqties. The format and content of the regulations are quite similar 

with the main difference being the stringency of the lb/day or tpy limits. The limits proposed are 

based on those fiom the Maricopa County regulation because it provides more specific 

applicability requirements. 

Section 2.0 - General Operating Requirements 

This section is intended to cover all sources of VOC in order to provide standard operating 

procedures for the handling and use of VOC-containing materials. The requirements are 

included in a separate section to avoid repeating requirements in the specific source category 

regulations and to cover the entire population of sources. Most State rules include these types of 

requirements, either in a separate section or in the individual source specific sections, thus the 

proposed requirements are based on several different State/local regulations and were chosen for 

language clarity and ease of understanding. 

Section 3.0 - Solvent Cleaning 

A CTG document exists for solvent cleaning, thus, State regulations are quite similar in their 

requirements for this source category. Table 4-2 uses the CTG and the regulations fiom the State 

of Delaware as a baseline, with differences contained in other State regulations highlighted. The 

requirements in the CTG are considered Reasonably Available Control Technology @ACT)- 

level controls, thus this level of control is proposed. Once again, due to the similarity in State 

regulations, the proposed requirements are based on a compilation of StateAocal regulations 

chosen for clarity. Also, the work practice requirements for wipe cleaning included in the 

proposed ordinance are based on the State of Wisconsin's regulation. 

General VOC TSD-030901 Created on 3/9/01 25 
Section 4.0 - Surface Coating 

Surface coating requirements are typically a limitation on the VOC content of individual 

coatings. Some industries require certain specifications for coating performance, thus, a single 

"one-size-fits-all" limit that covers all categories of surface coating is not practicable. As a 

result, numerous CTG documents have been developed based on specific types of surface 

coatings. The CTG requirements represent RACT and most State regulations are based on the 

CTG, thus there is similarity among the universe of surface coating regulations. The main 

difference is how VOC content is determined (i.e., not including water and/or exempt 

compounds). 

The basis for the proposed surface coating section is primarily the Maricopa County rule, In 

order to include surface coating operations that could potentially locate on GRIC land in the 

future, additional regulations were consulted. The regulations for Maine and Alabama were used 

due to their format and ease of understanding, All three regulations are based on the CTG 

documents and include a different list of surface coating operations with some overlap. The 

provisions for application methods and controls for spray coating are based on the Maricopa and 

Pinal County requirements. 

Section 5.0 - Architectural Coating 

Architectural coatings are usually treated separately fiom other surface coating operations. 

Table 4-4 includes regulations fiom the State of Arizona, as well as Maricopa and Pinal 

Counties. The Maricopa County and South Coast AQMD rules include an extensive list of 

coatings with limits on VOC content. There is limited architectural coating on GRIC land, thus 

the proposed requirements are based on the more concise, yet still protective, State of Arizona 

and Pinal County regulations. 

Section 6.0 - VOC Storage and Transfer 

Most State regulations include restrictions on VOC handling, storage, transfer, and disposal. The 

requirements for handling and disposal of VOC-containing materials are covered under Section 

2.0. The main variability between State regulations is among applicability provisions such as 

vessel size and vapor pressure cutoffs. The Maricopa County regulations limit applicability to 

bulk plants and terminals, however it was determined that requirements for storage and transfer, 

such as submerged fill pipes, should have broader applicability for the proposed ordinance. The 

State regulations were investigated to determine reasonable size cutoffs, and a vapor pressure 

cutoff was included based on the volatility of VOC-containing substances below the threshold. 

The proposed requirements are primarily based on the regulations from the States of Louisiana 

and Oklahoma due to the level of control required without being unduly cumbersome.

shall be considered as a member of the group having the least allowable percent of the total 

volume of solvents. 

Section 6.0 - VOC Storage and Transfer 

Applicability 

Rule 1, Section 6.0 applies to the storage of volatile organic compounds in stationary tanks, 

reservoirs, or other containers, and the transfer of volatile organic compounds fiom a storage 

vessel to a tank truck, trailer, or railroad tank car. 

VOCs with a true vapor pressure less than 1.5 pounds per square inch absolute (psia) under 

actual storage conditions are exempt from this section. 

Storage of VOCs 

Exemption. VOC storage vessels that are subject to equipment standards (e-g., a fixed roof 

in combination with an internal floating cover, an external floating roof, or a closed vent 

system and control device) in 40 CFR Part 60 Subparts K, Ka, or Kb are exempt. 

Storage capacities greater than 40,000 gallons. Each VOC storage vessel with a capacity 

of more than 40,000 gallons shall be a pressure vessel capable of maintaining working 

pressures that prevent the loss of VOC to the atmosphere or be equipped with a permanent 

submerged fill pipe and one of the following vapor-loss control devices: 

1. An external floating roof that consists of a pontoon type or double-deck type cover, or a 

fixed roof with an internal-floating cover. The cover shall rest on the surface of the 

liquid contents at all times (i.e., off the leg supports), except during initial fill, when the 

storage vessel is completely emptied, or during refilling. When the cover is resting on 

the leg supports, the process of filling, emptying, or refilling shall be continuous and shall 

be accomplished as rapidly as possible. The floating roof shall be equipped with a 

closure seal, or seals, to close the space between the cover edge and vessel wall. Floating 

General VOC TSD-03090 1 Created on 31910 1 5 7 
roofs are not appropriate control devices if the VOCs have a true vapor pressure of 11.1 

psia (76.6 kPa) or greater under actual conditions. 

2. A vapor-recovery system that consists of a vapor-gathering system capable of collecting 

85 percent or more of the uncontrolled VOCs that would otherwise be emitted to the 

atmosphere and a vapor-disposal system capable of processing these VOCs to prevent 

their emission to the atmosphere. 

3. Other equipment or methods that are of equal efficiency for purposes of air pollution 

control may be used when approved by the DEQ prior to installation. 

Storage capacities of greater than 250 gallons to 40,000 gallons. Each VOC storage 

vessel with a capacity greater than 250 gallons and up to 40,000 gallons shall be equipped 

with a permanent submerged fill pipe, be a pressure vessel capable of maintaining working 

pressures that prevent the loss of VOC to the atmosphere, or be equipped with a vaporrecovery system as described above. 

Loading of VOCs 

Exemption. Loading facilities subject to the requirements of 40 CFR Part 60 Subpart XX or 

40 CFR Part 63 Subpart R are exempt. 

Loading facilities with throughput greater than 40,000 gallonslday. Each VOC loading 

facility with a throughput greater than 40,000 gallonslday from its aggregate loading pipes 

shall be equipped with a vapor-collection and disposal system unless all tank trucks, trailers, 

or railroad tank cars are bottom loaded with hatches closed. 

1. Va-por-collection portion of the wstem. When loading VOCs through the hatches of a 

tank truck, trailer, or railroad tank car, using a loading arm equipped with a vapor 

collecting adapter, a pneumatic, hydraulic, or mechanical means shall be provided to 

ensure a vapor-tight seal between the adapter and the hatch. When loading is effected 

through means other than hatches, all loading and vapor lines shall be equipped with 

fittings that make vapor-tight connections and that must be closed when disconnected or 

that close automatically when disconnected. 

2. Vapor-disF>osal wrtion of the system. The vapor-disposal portion of the system shall 

consist of a vapor-liquid absorber system with a minimum recovery efficiency of 90 

percent by weight of all the VOC vapors and gases entering such disposal system, or a 

variable-vapor space tank, compressor, and &el-gas system of sufficient capacity to 

receive all VOC vapors and gases displaced from any tank truck, trailer, or railroad tank 

car being loaded. 

Loading facilities with throughput equal to or less than 40,000 gallons per day. Each 

loading pipe at a VOC loading facility with an aggregate throughput of 40,000 gallonslday or 

less shall be equipped with a system for submerged filling of tank trucks, trailers, or railroad 

tank cars that is installed and operated to maintain a 97 percent submerged factor. This 

applies to vessels with a capacity greater than 200 gallons. 

Provisions must be made to prevent spills during the attachment and disconnection of filling 

lines or arms. No liquid or gaseous leaks shall exist during loading or unloading operations. 

Tnspection for visible liquid leaks, visible fumes, or significant odors resulting from VOC 

dispensing operations shall be conducted by the owner or operator of the VOC loading 

facility or the owner or operator of the tank truck, trailer, or railroad car. VOC loading or 

General VOC TSD-030901 Created on 31910 1 5 8 
unloading through the affected transfer lines shall be discontinued immediately when a leak 

is observed and shall not be resumed until the observed leak is repaired. 

Monitoring 

The owner and operator of any subject loading facility shall be required to perform an 

inspection of each loading rack handling volatile organic compounds for facility vapor leaks 

or liquid leaks, and the vapor collection system and vapor disposal system, if applicable, on 

the following schedule: 

1. monthly, if sight, sound, and smell are used as detection methods; 

2. quarterly, if an organic vapor analyzer is used to monitor for vapor leaks. 

Each detection of a leak shall be repaired or replaced within 72 hours. The repaired or 

replacement component shall be re-inspected the first time the component is in operation 

after the repair or replacement. 

The owner or operator of any floating roof tank subject to this section shall inspect the tank 

and seals at least once every 6 months to determine ongoing compliance with both the 

applicable standards of this section and any permit conditions pertaining to the tank. 

Determinations of secondary seal gap area on external floating roofs can be made only once 

per year. Records of these inspections shall be maintained and made available to the DEQ 

upon request. 

All storage tank gauging devices, anti-rotation devices, accesses, seals, hatches, roof drainage 

systems, support structures, and pressure relief valves shall be maintained and operated to 

prevent detectable vapor loss except when opened, actuated, or used for necessary and proper 

activities (e.g., maintenance). Such opening, actuation, or use shall be limited so as to 

minimize vapor loss. Floating roof tanks shall have no visible holes, tears, or other openings 

in the seal or in any seal fabric. 

Detectable vapor loss shall be determined visually, by touch, by presence of odor, or using a 

portable hydrocarbon analyzer. When an analyzer us used, detectable vapor loss means a 

VOC concentration exceeding 10,000 ppmv. Testing and calibration procedures to 

deterinhe compliance &dl be consistent with EPA reference method 21 of 40 CFR Part 60. 

The reference compound may be methane or hexane, and a leak is dehed as a reading of 

10,000 ppmv of the reference compound. 

For tanks subject to this section, keep accurate records of the liquids stored in such tanks 

including either the true or the Reid vapor pressure ranges of each stored liquid. 

For loading facilities subject to this section, keep a daily record of the total throughput of 

VOC loaded at the facility, and the number of delivery vessels loaded at the facility and the 

quantity and type of VOC loaded. 

The results of inspections required by this section, including a record of any leaks found at 

the facility and the corrective actions taken. 

General VOC TSD-030901 Created on 3/9/01 59

including the piping outside of the loading area, shall be conducted according to EPA 

Reference Method 21. 

D. True Vapor Pressure: True vapor pressure shall be determined by ASTM Method 2879- 

83 and by temperature measurement under actual conditions using an instrument accurate 

to within rt 1 degree Fahrenheit or 5 0.5 degree Celsius. For purposes of recording and 

rewg, the Reid vapor pressure and the foregoing temperature detea-mination may be 

used in conjunction with the method of American Petroleum Institute Bulletin 2517, 

February, 1980, to determine true vapor pressure, unless the DEQ specifies ASTM 

Method 2879-83. 

E. Reid Vapor Pressure: Reid vapo~ pressure shall be determined by ASTM Method 

D323-82 or by ASTM Method D-5 191.
