RE:Notification of Potential Enforcement Action for Violations of Section 112 (r) of the Clean.
Air Act
Dear EHS Manager Sandra Cubas:
As you know, representatives from the U.S. Environmental Protection Agency, Region 9 (" EPA ")
conducted an inspection on June 6, 2023, of the TST, Inc. (" Company ") facility located at 11601
S. Etiwanda Avenue Fontana, CA, 92337 (" Facility "). The purpose of the inspection was to
determine compliance with requirements under the Emergency Planning and Community Right-
to - Know Act (" EPCRA ") sections 304-312, 42 U.S.C. 11004-11022; the Comprehensive
Environmental Response Compensation and Liability Act (" CERCLA ") section 103, 42 U.S.C
9603; the Risk Management Program (" RMP ") of section 112 (r) (7), of the Clean Air Act
(" CAA "), 42 U.S.C. 7412 (r) (7); and the General Duty Clause (" GDC ") of section 112 (r) (1) of the
CAA, 42 U.S.C. 7412 (r) (1).
Based upon the information obtained during our investigation, EPA is prepared to initiate a civil
administrative action against the Company to ensure compliance with federal law and assess a
penalty pursuant to section 113 of the CAA, 42 U.S.C. 7413. The anticipated administrative
action includes violations of section 112 (r) of the CAA, 42 U.S.C. 7412 (r), and its implementing
regulations.
After reviewing the Company's responses to EPA's previous information requests, EPA is
considering the allegations described below against the Company. For each allegation, the
corresponding area of concern (" AOC ") mentioned in EPA's Inspection Report sent to the
Facility on August 18, 2023, is provided below.
CAA, 40 C.F.R. Part 68-RMP
1) Hazard Assessment. The Company did not adequately document its hazard assessment as

violation of 40 C.F.R. 68.65 (d) (2) and (3), specifically:
i) The National Fire Protection Association (" NFPA ") diamonds were not affixed to
entry gates or doors associated with the Chlorine Vaporizer Building.2 (AOC 6)
ii) Chlorine storage Tank No. 1 did not have a diked area and sump installed around the
tank to contain the contents if a liquid chlorine release occurs, and the Facility did
not provide documentation of alternative safeguards. (AOC 7)
iii) The gates and doors present in the chlorine storage area and Chlorine Vaporizer
Building lacked panic hardware.4 (AOC 8)
1 The American Society of Mechanical Engineers (" ASME ") Boiler and Pressure Vessel (" B & PV ") Code Section VIII
UG-120 requires a data report to be prepared and available for each pressure vessel.
2 Section 60.5.1.8.2.1 of NFPA 1 (2021) and Section 6.1.8.2.1 (3) of NFPA 400 (2019) state, " Visible and hazard
identification signs in accordance with NFPA 704 shall be placed at the following locations except where the AHJ
has received a hazardous materials management plan and hazardous materials inventory statement in accordance
with Section 1.11 and 1.12 and has determined that omission of such signs is consistent with safety:... (3) At
entrances to locations where hazardous materials are stored, dispensed, used, or handled in quantities requiring a
permit. "
3 Section 6.1 of the Chorine Institute Pamphlet 5 (2017) states, " All new stationary chlorine storage tanks should be
installed in a diked area. The diked area should have a sloping floor leading to a sump. Specific procedures should
be provided for emptying rainwater from the diked area. The diked area, including the sump, should be designed
to hold the contents of 110% of the largest storage tank. "

vii) Piping supports above Chlorine Storage Tank No. 2 were severely corroded and
broken (AOC 12).
viii) Chlorine piping throughout the Facility was not adequately labeled.9 (AOC 13)
3) Process Hazard Analysis (" PHA "): The Facility did not adequately document its PHA as
follows:
a) The Facility's 2019 PHA listed external flooding as a possible risk, but the description
says, " No more of a hazard than other similar facilities. " However, the Facility has an
above - average flooding risk for RMP facilities, according to a US Government
Accountability Office climate change report. 10 Thus, the Company did not adequately
consider natural hazards in its PHA, in violation of 40 C.F.R. 68.67 (c) (5). (New AOC)
b) The Company had inadequate PHA recommendation tracking. The due date for all but
one recommendation was listed as July 1, 2020, in the PHA (and the other was July 1,
2021), but there were still incomplete recommendations as of July 2023, in violation of
40 C.F.R. 68.67 (e). (New AOC)
4) Training: Chlorine delivery truck drivers were not trained to operate the chlorine storage
tank filling valves, in violation of 40 C.F.R. 68.71 (c). (AOC 16)
5 Section 3.4 of the Chlorine Institute Pamphlet 66 (2007) states, " An Emergency Kit C should be on site in a
location sufficiently away from the tank car so it will be accessible during an emergency. The kit should be
inspected frequently to ensure the equipment is ready for use. "
6 Section 6.2.1.5 of NFPA 400 (2019) states, " Buildings or portions thereof in which explosive, flammable,
combustible, corrosive or highly toxic dusts, mists, fumes, vapors or gases are, or might be emitted, shall be

the General Duty Clause requirement to design and maintain a safe facility taking such steps
necessary to prevent releases:
a) Piping was suspended from other piping using ropes. 12 (AOC 15)
b) The hoists used to move material from the furnaces are adjacent to chlorine piping and
were not being inspected in accordance with applicable RAGAGEP. 13 (AOC 17)
c) The propane storage tank permit to operate was expired. 14 (GDC AOC 1)
d) The propane storage tank nameplate was corroded and illegible. 15 (GDC AOC 2)
11 Section 10.8 of the Chlorine Institute Pamphlet 6 (2020) states, " A protective coating system (for example, an
epoxy - based system) on the pipe should be considered to limit external corrosion. Painting specifications should
consider the environment. " Also, Section 12.2 of the Chlorine Institute Pamphlet 6 (2020) states, " As part of a good
overall preventative maintenance program, consideration should be given to ensuring that the following items are
checked periodically and corrected as needed... paint condition. " This section goes on to state " consideration
should be given to repainting on a regular basis, with timing determined by individual site conditions. This will
maximize pipe life and minimize leaks by minimizing external corrosion. "
12 Manufacturers Standardization Society (MSS) Recommended Practice (RP) -58 (2009) Section 6.13 states, " Pipes
shall not be suspended directly from each other unless formal calculations are performed and accepted by the
responsible Piping Design Engineer. If no calculations have been made, the individual hanger for each horizontal
pipe in a vertical bank shall have the load transmitted directly to the rods above, not the pipe. "
13 Section 16-2.1.5 of ASME B30.16 (2017) states that facilities should conduct and document an annual inspection
of the hoists that includes fasteners for the following conditions: "... 2) evidence of loosening, 3) load blocks,
suspension housings, hand chainwheels, chain attachments, clevises, yokes, suspension bolts, shafts, gears,
bearings, pins, rollers, and locking and clamping devices for evidence of wear, corrosion, cracks, and distortion, 4)
hook - retaining nuts or collars, and pins, welds, or rivets used to secure the retaining members for evidence of
damage, 5) load sprockets, idler sprockets, drums, and sheaves for evidence of damage and wear,... 13) welded
link chain for gouges, nicks, weld spatter, corrosion, and distorted links. Slacken the chain and move the adjacent
links to one side to inspect for wear at the contact points. "
14 California Code of Regulations, Title 8, Division 1, Chapter 4, Subchapter 1 (Unfired Pressure Vessel Safety
Orders), Article 5 (LP-Gas Systems), Section 470, Permit to Operate states, " (a) Except during the time a request for
a permit remains unacted upon, no employer or employee shall use or cause to be used any pressure vessel for the
storage or transportation of LP-Gas without first securing from the Division a permit to operate such container. (b)
Permits to operate dispensing units, trap tanks, and skid tanks shall expire in not more than 3 years while the
permit to operate transportation tanks, mobile fuel tanks, and storage tanks shall expire in not more than 5 years. "
15 ASME B & PV Code, Section VIII, Division 1, UG-119 (a) states, " Nameplates shall be used on vessels except when
markings are directly applied in accordance with UG-118. Nameplates shall be metal suitable for the intended
service and shall bear the markings called for in UG-116. " Also, ASME Boiler and Pressure Vessel Code, Section VIII,
Division 1, UG-116 states that each pressure vessel nameplate shall include the official certification mark, name of
