Lakeland, FL 33813
Dear Mr. Maron:
This is in response to your January 8, 2006 letter requesting clarification of the hazardous
materials training requirements under the Hazardous Materials Regulations (HMR; 49
CFR Parts 100-180). Specifically, you ask whether the training requirements apply to
employees at your company.
In your letter, you state that your company, KCI, operates a chemical manufacturing
facility in Florida and has obtained a radioactive materials license from the Florida
Department of Health, Bureau of Radiation Control (FDHBRC). The waste stream from
this facility, hydrochloric acid, is disposed by deep well injection into limestone
formations at a depth of more than 4,000 feet below ground surface, as permitted by the
State of Florida. As part of the injection process, 2,000 gallons of oil are mixed with a
radioactive tracer (5 millicuries of Scandium 46) and injected into the well on a quarterly
basis. The oil protects the steel well casing from corrosion and provides a means of
verifying that the well casing fluid is not leaking. The integrity of the well is verified by
lowering a gamma sensing tool into the well to identify the location of the oil via the
radioactivity of the Scandium tracer. You state that the tracer is purchased from a
company in New Mexico and received by KCI via overnight delivery at the injection site,
where it is mixed with the oil and injected into the well on the day of delivery.
Employees of KCI hand-carry the tracer from the receiving office to the injection well.
You ask whether employees who conduct these specific duties are subject to the
hazardous materials training requirements of the HMR.
The answer is no. Hazmat employees are subject to the hazardous materials training
requirements found in § 172.704. A hazmat employee, as defined § 171.8, is a person
who is employed by a hazardous materials employer and who, in the course of
employment, directly affects hazardous materials transportation safety. For the purposes
of the HMR, "transportation in commerce" begins when a carrier takes possession of a
hazardous material for the purpose of transporting it and continues until the package
containing the hazardous material arrives at its destination.

Re:
Need for Clarification
49 CFR Part 172, Subpart H Training
K.C. Industries, L.L.C.
Mulberry, Florida
Dear Ms. Gorski,
On behalf of K.C. Industries, L.L.C., (KCI), this letter is submitted to respectfully request your
interpretation of the above-referenced rule citation. The following presents a description of the
conditions at the KCI facility and identifies the question pertaining to the need for hazardous
materials training under the requirements of the U.S. Department of Transportation (USDOT).
BACKGROUND
KCI operates a chemical manufacturing facility in Mulberry, Florida. The waste stream from this
facility, a weak hydrochloric acid, is disposed by deep well injection. The fluid is injected into
limestone formations at a depth of more than 4,000 feet below ground surface. The disposal of
the waste stream is permitted by the State of Florida.
As part of the operation of the injection well, approximately 2000 gallons of oil are injected into
the well on a quarterly basis (every 3 months). Prior to injection of the oil, a radioactive tracer (5
millicuries of Scandium 46) is mixed with the oil. Since the oil is lighter than the plant waste
stream being injected, as well as the natural fluid existing in the injection formation, the oil rises
to the top of the "cavity" that has been formed in the limestone formation. The injection of the oil
serves two purposes: to protect the steel well casing from corrosion due to the high chloride
content of the formation fluid and the corrosiveness of the injected waste ctream; and, to
provide a means of verifying that fluid is not leaking upwards around the outside of the wel!
casing. The latter is verified by using a gamma sensing tool that is lowered down the well to
identify the location of the oil via the radioactivity given off by the Scandium tracer that is mixed
In order to receive and inject the radioactive tracer, KCI has obtained a Radioactive Materials
License (No. 3126-1) from the Florida Department of Health, Bureau of Radiation Control
(FDHBRC). Rules governing the issuance of Radioactive Materials Licenses are contained in
Chapter 64E-5, Control of Radiation Hazard Regulations, of the Florida Administrative Code
(F.A.C.). Sections 64E-5.1501 and 64E-5.1502, F.A.C. require licensees to comply with the
applicable requirements of the USDOT specified in Title 49, Code of Federal Regulations
(CFR). More specifically, Part 172, Subpart H of 49 CFR requires all employees involved with
work that directly affects hazardous material transportation safety to receive hazmat training

need tor this training for the tollowing reasons.
• KCI does not ship, prepare the tracer for shipment or transport the radioactive tracer.
The tracer is purchased from SpectraTec Services in Albuquerque, New Mexico, who
ships the tracer via overnight delivery (Federal Express). Federal Express delivers the
tracer to the site and it is mixed with the oil and injected on the day of delivery. The only
"transporting" of the tracer by KCI is when it is carried by hand from the Receiving Office
to the injection well.
•
In discussions with personnel from the USDOT's Hazardous Materials Answer Line, they
have stated that the hazmat rules apply only to persons who transport, or offer for
transport, hazardous materials.
• In the history of receiving the radioactive tracer at the site (over 20 years), there has
never been a need to ship the tracer back to the supplier.
• KCI has developed a Radiation Safety Manual and Operating Instructions, which must
be approved by the FDHBRC prior to issuance of the Radioactive Materials License, that
describes the procedures used to handle the radioactive tracer from receipt to injection
with the oil.
Personnel named on the Radioactive Materials License to handle the tracer material
have undergone training in the handling of radioactive materials in accordance with the
rules of the FDHBRC.
The FDHBRC has stated that the requirement for hazmat transportation training will be waived
for the KCI site if concurrence can be obtained from the USDOT that such training is not
required under 49 CFR Part 172 for the receipt of radioactive materials at the site. Since KCI
only receives and does not ship or transport the radioactive tracer, KCI believes it is not
subject to the training required under 49 CFR Part 172, Subpart H

We will greatly appreciate your written response to this matter. If you have any questions,
please do not hesitate to contact me at 813-781-2670 or Mr. Paul Maasen of KCI at 636-327-
