IV. Pre-Tour Discussion 

Introduction 

Philtex/Ryton Introduction 

Upon entering the Philtex/Ryton Complex, the EPA and PES visitors were escorted into a 

conference room where they viewed an orientation video that presented the facility's safety 

regulations. Following the safety brief, Mr. Mike Nims presented a brief overview of the 

Philtex/Ryton Complex. Specifically, he described the manufacturing operations carried out at 

the Complex, which is divided into three distinct areas: Philtex Area I, Philtex Area II, and the 

Ryton unit. A sheet summarizing the various product lines was distributed to the visitors 

(Attachment 1). A detailed discussion of Mr. Nims' presentation can be found in the Facility 

Processes section of this memorandum. A copy of the facility's Texas permit was also provided 

(Attachment 2). 

EPA Introduction 

Following the facility introduction, Mr. Steve Shedd, EPA, discussed the background of 

the EPA's regulation of hazardous air pollutant (HAP) emissions. Prior to the Clean Air Act 

Amendments of 1990 (CAAA), regulations were on the basis of individual HAP and a limited 

number of regulations were completed. The CAAA included a HAP list and prescribed that rules 

be developed for categories of sources (industrial types). The stringency of the Organic Liquids 

Distribution (non-gasoline) rule (for existing sources) will be based on "floor" levels of control 

representing the control achieved by the average of the top 12 percent of sources in this category. 

The standards are slated to be proposed in 1999, with promulgation of the final rule in November 

2000. 

Mr. Shedd proceeded to describe the EPA's procedures for handling information that 

companies consider to be confidential business information (CBI). The company will have an 

opportunity to review the draft site visit report prepared by the EPA project team, and to 

comment on its accuracy and to identify any CBI. The report, with any CBI removed, will be 

made a part of the public record for this rulemaking. Philtex/Ryton representatives were asked to 

identify whether any of the information in the conversations or the handout was confidential. No 

information presented was claimed to be confidential.

Facility Processes 

The Philtex/Ryton Complex is situated next to the Phillips Borger Refinery and Natural 

Gas Liquids Center in Borger, Texas, which is located near the northern extremity of the Texas 

Panhandle. The Complex was constructed in 1943 and employs 290 people, of which 

approximately 284 are associated with organic liquid distribution functions other than gasoline. 

The facility operates on a 24 hr/day, 7 days/week, 52 weeks/yr basis, and the representatives 

estimated that it is operating at approximately 75% capacity. The SIC code for the plant site is 

2869, which covers industrial organic chemicals production. 

According to Mr. Nims, the Complex is divided into two major sections. The Philtex 

plant produces, blends, purifies, and repackages specialty organic chemicals. In Area I, the CPU 

manufactures various products including mercaptans (natural gas odorant) using feedstocks 

supplied by the refinery. Unit 5.1/5.2 makes crude and spec isobutylbenzene (an ingredient in 

the medicine ibuprofen). Specialty hydrogenation reactions are also carried out. In the fuels 

blending area, specialty fuels (EPA reference, smokeless, etc.) are produced. Area II has a great 

deal of production flexibility, producing about 300 products in mostly batch processes. Some of 

these include sulfolane, mercaptans, disulfides and polysufides, and alkylated aromatics. The 

Ryton plant produces and compounds Ryton®-brand polyphenylene sulfide plastic. 

The plants receive organic and inorganic chemicals as well as refined petroleum products 

by pipeline, by rail tank car, by tank trailer, and in non-bulk and semi-bulk containers. Materials 

are unloaded, stored, transferred, reacted, purified, blended, repackaged, or otherwise used. 

Some materials may be reacted or purified repeatedly. Approximately 20 million gallons of 

finished organic chemicals consisting of over 300 different products are loaded into rail tank 

cars, tank trailers, intermodal tanks, totes, drums, bags, cans, bottles, and various other packages. 

Finished plastic is loaded into boxes and bags. 

Organic liquids handled at Philtex/Ryton Complex fall into the general categories of raw 

materials, blend stocks, intermediates, products, and by-products. These categories are not 

mutually exclusive, and a material may fall into more than one category. Mr. Nims provided an 

example in which a product is purchased and then repackaged directly into smaller containers for 

sale, or the product may be blended into a variety of mixtures, or further purified. Major organic 

liquid product streams include specialty organic chemicals, specialty fuels, and specialty 

solvents. For purposes of the Organic Liquids Distribution Section 114 survey, distribution 

activities were mostly restricted to raw materials and products. 

Approximately 20 to 25 percent of the organic liquids transferred into or out of the plant 

are "surveyed liquids" (i.e., have a true vapor pressure s.0.1 psia and HAP content _: 1,000 

ppmw). Many of the products that the company reported in the EPA's O.L.D. Section 114 

survey were grouped to reduce complexity. 
P.5 

Site Visit Memo/Philtex-Ryton Complex 

March 18,1999 

Page 4 

Some of the grouped liquids within the survey include: 

95 gasoline blends 

13 leaded gasoline blends 

5 different groups of n-heptane 

4 grades of reformates 

2 grades of light alkylates 

3 grades of toluene 

3 grades of n-hexane 

2 grades of isooctane 

2 grades of cc gasoline 

Additionally, ungrouped liquids reported in the survey include (not exhaustive): 

1,3-butadiene 

Cosdenol 104 

dibutyl ether/toluene mixture 

ethyl chloride 

ethylene dichloride 

isohexanes 

isomerate 

methanol 

methyl tert-butyl ether 

methylcyclohexane 

motorfuel anti-knock compound 

triethylamine. 

Wastewater 

According to the survey response that was filled out by the Philtex/Ryton Complex, 

wastewater associated with O.L.D. type operations is primarily a product of cleaning equipment. 

Drains are controlled using p-traps and other types of water seals. Process wastewater from the 

plant, which includes O.L.D. wastewater, is conveyed through a covered system to an enclosed 

phase separator, which is vented to a flare. After phase separation, the wastewater is pumped to 

a fixed-roof atmospheric storage tank. The storage tank drains through a skimmer and then to 

the surge tanks to the refinery's industrial wastewater treatment system. Solids are treated at the 

refinery using thermal desorption. The Philtex/Ryton environmental staff estimates that 

approximately 350,000 gallons of wastewater result annually from organic liquid distribution 

type operations.

Equipment Leaks 

Philtex/Ryton uses the emission factors developed for SOCMI equipment to calculate 

fugitive emissions. However, the Philtex/Ryton staff indicated that SOCMI factors may 

overestimate fugitive emissions for O.L.D. type operations because of intermittent use of 

equipment, and because lines are blown dry with nitrogen after each use. 

MACT Coverage and Annual Emissions 

The Philtex/Ryton staff was asked to provide information on applicable NESHAP/MACT 

coverage at the facility. Applicable MACT standards include the Hazardous Organic NESHAP 

(HON), the under-development Miscellaneous Organic NESHAP (MON), and the Gasoline 

Distribution NESHAP. The staff anticipated that the Organic Liquids Distribution NESHAP 

will cover organic liquid distribution activities at the Philtex/Ryton Complex. The facility is in 

an attainment area for ozone. 

Of the 150 tons of HAP which were estimated to be emitted in 1997, approximately 5% 

(7.5 tpy) are from organic liquids distribution type operations. 

V. Facility Tour 

Upon completing discussions regarding the facility's operations and the survey, the 

Philtex/Ryton staff took the EPA project team on a tour of their facility. The first stop was at a 

small container/package filling station (Dock 1). Small containers, including 5-gallon cans, are 

filled at this location. No vapor recovery is used for the filling of small containers; nevertheless, 

ventilation is provided to lessen the exposure of employees using the equipment.. Nitrogen 

purging is utilized on small containers to prevent explosions/fire while filling with specialty 

fuels, the predominant category of organic liquid transferred into small containers at this site. 

Following the small container/package filling site, the group proceeded to the loading site 

for butanes and propanes. Pressure tanks were observed, which were filled by weight. The 

facility plans to control the butane emissions in the future with the use of a flare. 

The EPA project team had expressed interest in obtaining detailed information regarding 

railcar loadings and unloadings. Following the cylinder filling area, the staff took the EPA 

project team to the railcar loading rack. The team observed numerous tank cars that were 

classified by the Department of Transportation (DOT) as being 11 IA 100-W-l (30,000 gallon, 

general purpose) railcars, some of which were being top loaded. These cars have two vapor 

relief valves (set at 75 psi) and two liquid valves (used for loading purposes). The railcar itself is 

rated at 280.5 psia. The main liquid hatch is equipped with a gasket, which has to be compatible 

with the liquid that is being stored or loaded in the railcar. Numerous replacement gaskets were 

-D 
P.7 

Site Visit Memo/Philtex-Ryton Complex 

March 18,1999 

Page 6 

observed at the railcar rack. Liquids observed being loaded included propylene, Sulfole 120, and 

Soltrol 130. 

Most of the loading/unloading on railcars occurs from the top, but some railcars can also 

be bottom loaded. For unloading purposes, nitrogen is often pumped into the tank, which forces 

the liquid out of the railcar. While loading railcars, the volume and level of liquid are measured 

by time and by the use of a gauging device, which is mounted on the top of the tank. While 

filling tanks, hydrocarbon sensors are activated at the filling dock to detect any leaks or spills 

coming from the railcar. The railcars are filled at an average rate of 100 to 130 gallons per 

minute. 

Following the railcar rack, the team was led to Dock 2, which is a drum filling operation. 

Drums at this location are filled by weight, and use a submerged fill lance so as to avoid splashloading of drums. The drum loading operation has an automatic shutoff function for when the 

desired weight is reached within the drum. No vapor recovery is used, but vapors are routed 

away from employees via a blower. At this location the facility was loading refined fuels, 

diesels, and isopentanes. Drips from the fill lance and small spills from the loading operation 

were being run to a slop tank for storage and eventual treatment. 

Mercaptans, non-HAP liquids that are used as an odorant in natural gas (and other gases 

used for fuel) are loaded using a venturi scrubber/packed tower as an odor-control device. 55-

gallon drums are placed within an enclosure, and filled by weight. Vapors emanating from the 

filling operation are vented to the scrubber. 250-gallon totes are also filled with mercaptans and 

vented to the scrubber. Since the scrubber will not remove DMS, the facility is considering 

adding a carbon adsorption system before the scrubber. 

The team briefly stopped at a "multi-purpose" tank truck loading rack. No HAPcontaining liquids are loaded at this rack, and the Philtex/Ryton staff indicated that mercaptans 

are blended and loaded into tank trucks at this site. The rack is also equipped with a flare 

connection to control emissions. 

After visiting the mercaptan loading facility, the tour visited the packaged products 

loading area. At this site 55-gallon drums are loaded with high purity hydrocarbons (such as 

isooctane). In addition to 55-gallon drums, 35- and 55-gallon cylinders are also filled. No vapor 

control is used to control emissions from filling the 55-gallon drums. 

Following the packaged products loading area, the team was led to Unit 5 Tank Truck 

Rack, which is used to load gasolines. The rack has four loading spots, and a threecompartmented tank trailer was observed on site (inactive). Emissions from the transfer of 

gasoline at this rack are routed to a thermal oxidizer which is manufactured by Calladis 

Technologies, Inc. The thermal oxidizer uses natural gas as a supplemental fuel, and it operates 
P.8

March 18,1999 

Page 7 

at approximately 1,240 degrees Fahrenheit. The operating temperature is continuously 

monitored. The thermal oxidizer was put into operation in January 1998. The Philtex-Ryton 

staff reported that they had electrical problems during the initial start-up of the thermal oxidizer. 

VI. Post-Tour Discussion 

Following the tour of the facility, the EPA project team and the Philtex/Ryton staff 

reconvened in the conference room for a debriefing. Some questions remained regarding the 

Section 114 survey, which were clarified at this time. After all of the company's questions were 

discussed and answered, the meeting was concluded. 

VII. Action Items 

No action items were identified at the conclusion of the meeting.

cooling tower, loading, unloading and tank emissions of carbon monoxide, nitrogen oxide, 

particulate matter, S02, and VOC must be calculated mondily and the monthly calculation 

and 12-mondi rolling annual total must be recorded. These emission rates will be 

combined widi the results from the flare testing, the initial (and subsequent) stack testing 

of the scrubbers, and fixed VOC sources (process fugitives) to calculated mondily VOC 

emissions. The accumulated total emission for each pollutant must be less than its 

respective permitted annual emission cap. 

Demonstration widi die hourly emission cap shall be made upon request of representatives 

of the TNRCC or any local program having jurisdiction. The permit holder shall have 

15 days from die date of die request to provide information for any single compound and 

45 days from the date of the request to provide information for multiple compounds. 

After calculating emissions as required by this condition, if die accumulated total annual 

emissions exceed the established ^annual emission caps, a report shall be submitted to the 

TNRCC Regional Office within 30 days.

SPECIAL CONDITIONS 

Permit No. 21918 

Page 22 

The report shall identify which emission caps were exceeded, cause of the exceedance 

(if known) and corrective action that will be taken. 

42. The emission caps in this permit are based on the control upgrades specified in 

Attachment B. The permit holder will implement the controls as specified in tiiis 

attachment or on any otiier schedule as necessary to comply with the emission caps. If the 

permit holder chooses to use alternative approaches to emission reductions to achieve the 

emission caps, the permit holder must maintain documentation as required under Special 

Condition No. 41. 

ADJUSTMENT OF EMISSION RATES 

43. The emission rate estimates for scrubbers, flares, wastewater, and cooling tower sources 

being tested as specified in die conditions of this flexible permit and die associated 

emission caps shall be adjusted as necessary to reflect consistency with testing results. 

Piping component counts and fugitive emission estimates for the current and final emission 

caps shall be adjusted as necessary to reflect actual component counts as shown by the 

required leak detection and repair program(s). Adjustments which result in an increase in 

estimated emissions shall require a permit amendment and decreases in emission estimates 

may be effected by die use of a permit alteration. 

FACILITY IDENTIFICATION NUMBERS 

44. By April 30, 1998, the permit holder shall request an alteration of die permit 

representations to alter Attachment C to include die Facility Identification Numbers for all 

sources as reported in the emissions inventory.

EMISSION SOURCES - MAXIMUM ALLOWABLE EMISSION RATES 

Emission Source Caps 

Permit No. 21918 

This table lists the maximum allowable emission rates and all sources of air contaminants on the applicant's 

property covered by this permit. The emission rates shown are those derived from information submitted as 

part of the application for permit and are the maximum rates allowed for these facilities. Any proposed 

increase in emission rates may require an application for a modification of die facilities covered by this permit. 

The sources and emission points authorized under this permit are noted in Attachment C, Emission Caps List. 

Compliance with the emission rates is based on the aggregate emissions of the sources noted on the Emission 

Cap List Table which are subject to that cap.
