Dear Mr. Copeland:
In a letter to the Pipeline and Hazardous Materials Safety Administration (PHMSA) dated
January 12, 2015, you requested an interpretation of the applicability of the 49 CFR Parts 192
and 195 requirements to your pipelines.
You stated that Wacker Polysilicon Notih America. LLC (Wacker) is constructing a chemical
plant in Charleston, TN. Inc! uded in the plant is the construction of two dedicated chemical
pipelines that will transport chlorine gas and sodium hydroxide liquid from Olin Corporation
(where the chemicals are manufactured) to Wacker's facility. The overall length of the
aboveground pipeline for both the chlorine gas and sodium hydroxide is approximately 5,000
feet. You stated that the pipelines cross underneath a county road through an open-to-air box
culvert that separates the two facilities (map provided). You asked for an interpretation as to the
applicability of PHMSA regulations to your pipelines.
You stated that § 192.1 does not appear to exclude the chlorine pipeline. It is your belief that
because chlorine gas is both toxic and corrosive. the chlorine pipeline may be regulated under
Part 192.
As to the sodium hydroxide pipeline, you stated that§ 195.1 provides exclusions and you believe
§ 195.l(b)(3)(ii) exempts the sodium hydroxide line because; (1) the length of line measured
outside of facility grounds is less than one mile; (2) the pipeline serves a manufacturing facility:
and (3) the pipeline does not cross a waterway used for commercial navigation. Therefore, it is
your belief that the sodium hydroxide pipeline is not regulated under Part 195.
Pmi 192 prescribes minimum safety requirements for pipeline facilities and the transportation of
gas. including pipeline facilities and the transportation of gas within the limits of the outer
continental shelf(§ 192.1 ). Also, § 192.3 defines the term ''gas" as natural gas. i1ammable gas.
or gas which is toxic or corrosive. Therefore, as you stated in your request letter, the
transportation of chlorine gas is regulated under Part 192 regulations.
Part 195 prescribes minimum safety standards and reporting requirements for pipeline facilities
used in the transportation of hazardous liquids or carbon dioxide. Section 195.2 defines
The Pipeline and Hazardous Materials Safety Administration. Office of Pipeline Safety provides written clarifications of the Regulations (49 CFR
Parts 190-199) in the form of interpretation letters. These letters reflect the agency's current application of the regulations to the specific facts

hazardous liquids as petroleum, petroleum products, or anhydrous ammonia. Therefore,
transportation of hazardous liquids by pipeline that is not petroleum, petroleum products, or
anhydrous ammonia (in this case sodium hydroxide) is not regulated under Part 195.
Ifwe can be offurther assistance, please contact Tewabe Asebe of my staff at 202-366-5523.

Re: Regulatory Jurisdiction Request, Wacker Polysilicon North America,
LLC; Charleston, TN
Dear Sir or Madam:
Wacker Polysilicon North America, LLC (Wacker) is constructing a chemical plant in
Charleston, TN located at 553 McBryant Road NW, Charleston, TN 37310. Included in the
plant is the construction of two, dedicated chemical pipelines that will transport chlorine gas
and sodium hydroxide liquid from Olin Corporation (where the chemicals are manufac-
tured) to Wacker's facility. The overall length of the aboveground pipeline is approximately
5,000 feet and it crosses underneath a county road (through an open to air box culvert) that
separates the two facilities. Please refer to Appendix A that provides an aerial view of the
route of the pipelines.
Chlorine
The scope of Title 49 CFR Part 192.1 includes pipelines that transport gas. Some exclu-
sions are listed in the rule, but none that appear to exclude the chlorine pipeline. It is
Wacker's interpretation that the chlorine pipeline may be regulated under 49 CFR part 192;
based primarily on the fact that chlorine gas is both toxic and corrosive.
Sodium Hydroxide
The scope of Title 49 CFR Part 195.1 includes pipelines that transport hazardous liquid.
Wacker interprets that the exclusion listed in 49 CFR Part 195.1 (b )(3)(ii) exempts the sodi-
um hydroxide line because; (1) the length of line measured outside of facility grounds is
less than one mile, (2) the pipeline serves a manufacturing facility, and (3) the pipeline
does not cross a waterway used for commercial navigation. Therefore, Wacker concludes

<<<PAGE 4>>>

that the sodium hydroxide pipeline is not regulated by the Federal Department of Transpor-
tation (USDOT).
As requested by USDOT personnel and pursuant to 49 CFR 190.11 (b); Wacker is request-
ing written regulatory interpretation of the US DOT regulatory jurisdiction/PHMSA rules ap-
plicability to each of the the Wacker pipelines described above. Please refer to our user ID
application request already filed with PHMSA and attached as Appendix B. This applica-
tion was filed in June 2014 based on our own rule interpretation that the chlorine line is
regulated. Since filing the application request, Wacker inquired to USDOT as to the status
of the processing of the application and we were directed to send this regulatory interpreta-
tion request to the Office of Chief Counsel.
If you have any questions necessary to provide clarifications or aid in processing our re-
quest or would like to discuss the topics for any reason, please contact me at (423) 780-
7953. You may return your response to Wacker either electronically at:
Jeremy.Copeland@wacker.com or via hardcopy to: Jeremy Copeland, Environmental
Manager, Wacker Polysilicon North America, PO Box 446, Charleston, TN 37310.
