Dear Mr. Beacon:
This responds to your letter of May 22, 1984, regarding the proposed construction of a Wilding at the Eau
Claire LNG plant site. The building would house five LNG plant personnel and serve as a gas/electric meter
maintenance shop.
In our opinion, the regulations in 49 CPR Part 193 do not prohibit construction of the building at the Eau Claire
LNG plant site. It is important to not, however, that if the building is. to be toed in relation to any of the LNG
plant processes, it would qualify as an "LNG facility" under the definition of that term in Part 193, and be
subject to applicable Part 193 requirements. Moreover, even if the proposed building is not an "LNG facility",
since it is to be located on the LNG plant site, it would be subject to the gas monitoring and alarm
requirements of 81.93.2819(f).
We do not think that the mere housing of-ING plant personnel during the course of non-LNG related meter
repair duties would be a usage sufficiently connected to LNG plied processes to qualify the building as in "LNG
facility." A more direct connection to LNG processes would be required. For example, your letter said the
personnel may perform security and operational response functions. If in so doing they use communication,
control, or monitoring equipment that is located in the building, the building would provide a direct link to
plant processes that would qualify the building as an "LNG facility." Examples of other usages that would make
the building an "LNG facility's would be the housing of emergency equipment, maintenance vehicles, or
maintenance materials.
We hope this information is helpful to you.
Sincerely,

Dear Mr. Beam:
On Tuesday, May 15, 1984, our Engineer in Gas Operations, Perry Kuznar, spoke with your associate, Walt
Dennis, on our proposal to build a combination gas/electric meter shop/maintenance building on our Eau
Claire, Wisconsin LNG Plant site. Our concern was that the existing 193 Code would disallow its construction
on that site for reasons within the Code. Upon talking with Mr. Dennis, however, it was decided that the
proposed building could be built on our site due to the following:
1. Eau Claire LNG Plant was built in 1968 and put into production on September 2, 1969. This preceded
the introduction of the 49 CFR Part 193 rules. The plant was built under the rules of NFPA 59A, 1967 edition.
There were no provisions for the regulation of new buildings on site at this time.
2. The proposed shop will house 5 LNG operators. These operators will have dual ratings in LNG operation
and in electric or gas meter repair. Having these men on site will give the following advantages:
a. Operators on site for at least 8 hours per day versus the approximate 2 hours per day at
present. Security of both the plant and its functions are greatly enhanced.
b. Response to plant alarms or malfunctions can be handled quickly by men on site versus calling
men in from a distant source.
c. Operators will be exposed more to the plant and thus remain more familiar with it than
someone who works there on a rotating basis (as we do now).
As was discussed with Mr. Dennis, we plan to make this new facility as safe as possible for the occupants who
work in it. We realize that although our plant is grandfathered, we still must try to conform to the highest
safety standards possible for our given situation.
In conclusion, we'd like to thank Mr. Dennis for his time to give us this information. Walt had said to keep on
file all information necessary on our plant and the codes it was built under for future reference, if needed, by
your office. We, therefore, are going to actively pursue the building of this combination meter shop
maintenance building on the Eau Claire LNG Plant site. If, for any reason you have exception to this proposed
building, we ask that you inform us of such in writing by June 30, 1984. After that time we will commence with
the construction of the building.
Thank you very much for your help.
Sincerely,
V. E. Beacom
Vice President
