Lake Tillery Hydroelectric Plant
Certificate of Coverage NCG500189
Montgomery County
Dear Mr. Zalme,
Enclosed you will find a copy of the Compliance Inspection report for the routine
inspection conducted on September 11, 2013 at the Lake Tillery Hydroelectric Plant, where I met
with you and Allen Stowe (Duke Energy Water Management). The purpose of this inspection
was to evaluate compliance with the requirements of the Wastewater General Permit
NCG500000 series. As part of the inspection, a tour of the plant was conducted. All
observations are in Section D. Summary of Findings/Comments of this inspection report. The
001 Outfall sampling point was noted as the tailrace. Please review . the following two
suggestions: #1) the limit pages for both the Once -Through Cooling Water and for the Sumps
and Drains have monitoring requirements for Chemical Oxygen Demand (COD) analyses on a
semi-annual schedule that is applicable when cleaning solvents are added to the system (please
see the three attachments to this report that refer to 2-Butoxyethanol, contained in Blaze -Off
MSDS, as a solvent), #2) NCG500189, Part I, A (3) refers to discharge from sumps. My
understanding is that although it may be permissible to sample from a point where similar
wastewaters (covered by this permit) have commingled, it is preferred that the applicable
parameters in Part I, A (3) be sampled at the main sump in a manner that future evaluation may
be made by the permit writer (during the peunit renewal cycle) so that appropriate improvements
may be made to the permit. Please consider sampling from the main sump for O&G and COD,
and please consider estimating the amount of flow from the sump as a Quarterly measurement.

that smells somewhat like ether. Most people can begin to smell 2-butoxyethanol in air at
0.10-0.40 parts of 2-butoxyethanol per million parts of air (ppm). These levels are about
500 times lower than the present standard for worker exposure. 2-Butoxyethanol has been found
in air, water, and soil as a contaminant. It is completely soluble in water and in most organic
solvents. This means that when 2-butoxyethanol and water or 2-butoxyethanol and organic
solvents are mixed, the mixtures form one layer, unlike mixing oil and water which separate into
two layers. 2-Butoxyethanol is a fire hazard when exposed to heat, sparks, or open flames.
. 2-Butoxyethanol in the environment comes from some industrial activities. It is usually produced
by a reaction of ethylene oxide with butyl alcohol, but it may also be made by the reaction of
ethylene glycol with dibutyl sulfate. 2 Butoxyethanol is widely used as<a solvent ui protective
surface coatings such as spray lacquers, quick -dry lacquers, enamels, varnishes, and latex paints.
It is also used as an ingredient in paint thinners and strippers, varnish removers, agricultural
chemicals, herbicides, silicon caulks, cutting oils, and hydraulic fluids:It. otler_uses=in metal`
cleaners; fabric dyes and inks -Wins tnal and householdcleaners.(as a degreaser), and dry-cleaning
compounds. It is also used in liquid soaps and in cosmetics.
The acetate (ass-e-tate) form of this chemical is 2-butoxyethanol acetate. It is also known as
ethylene glycol monobutyl ether acetate, butoxyethyl acetate, butyl glycol acetate, ethylene glycol
butyl ether acetate, acetic acid 2-butoxyethyl ester, glycol monobutyl ether acetate, Butyl
Cellosolve acetate, or Ektasolve EB acetate. Common abbreviations for 2-butoxyethanol acetate
include BEA and EGBEA. 2-Butoxyethanol acetate has been found in air, water, and soil as a
contaminant. It is a colorless liquid with a fruity odor. Most people can begin to smell

soluble in most organic solvents. This means that when 2-butoxyethanol acetate and water or 2-

OSHA: The legal airborne permissible exposure limit (PEL) is
50 ppm averaged over an.8-hour workshift.
NIOSH: The recommended airborne exposure limit (REL) is
5 ppm averaged over a 10-hour workshift.
ACGIH: The threshold limit value (TLV) is 20 ppm averaged
over an 8-hour workshift.
2-Butoxy Ethanol may be a CARCINOGEN in humans.
There may be no safe level of exposure to a carcinogen, so
all contact should be reduced to the lowest possible level.
n The above exposure limits are for air levels only. When skin
contact also occurs, you may be overexposed, even though
air levels are less than the limits listed above.

Productio
2-Butoxyethanol is produced by
monoethoxylation of butanol:
C2H40 + BuOH -- BuOC2H4OH
In 2004 t t tal European production
of all butyl glycol ethers amounted to
181 kilotons per annum (kt/a),
approximately 50% (90 kt/a) of which
was 2-butoxyethanol. World production
is estimated to be 200 to 500 kt/a, of
which 75% is for paints and coatings.
[citation needed]
Uses
2-Butoxyethanol is a solvent in paints
and surface coatings, as well as cleaning
products and inks. Other products that
