Andy Oxy Facility Lime Basins - 27 Heritage Drive
----_—__-- -- Buncombe-County,.North-Carolina.--
Dear Mr. Lovin,
A Notice of Violation (NOV) was issued to the Andy Oxy Company on January 5, 2015 -
following a site inspection of two earthen basins containing approximately 1,000 cubic
yards of calcium oxide, otherwise referred to as lime. The Division of Water Resources
(DWR) has reviewed the site and findings of the assessment and offer the following
comments.
The initial site inspection documented off -site migration of the stockpiled lime towards an
unnamed tributary to Smith Mill Creek; a Class C stream. The off -site migration appears,to
be confined to a nearby stormwater culvert and the west side of the dry lime basin. As part,
of fhe,NOV response, you were required to secure the stockpile of lime, assess and remove' ,
any off -site lime, and 'analyze groundwater pH in the vicinity of the earthen basins.
Environmental consultants Amec Foster Wheeler submitted an investigative report'on-May
29, 2015 detailing site assessment activities and efforts to remove any off -site lime. A total
of thirteen soil borings were collected downstream of the stormwater culvert. A small
localized deposit of lime intermixed with native soils was noted at borehole B-5.
Approximately 6.2 cubic yards of lime was removed from the west side of the dry lime
basin. The assessment and removal of off -site lime appears to be adequate. Therefore, no
further action is required with regards to the removal of lime.
The analytical results for both the surface water and groundwater samples indicate a pH
range of between 5 and 6, which appears to be analogous of background le_yels._Analytica!_-
results suggest the lime basins do not appear to be adversely impacting local groundwater
or surface water quality at this time. The Division has determined that the lime does not
meet the definition of industrial wastewater nor does it meet the definitions for solid waste
or wastewater residuals. Therefore, the storage of lime in two earthen basins does not
require a permit and can continue in its present state.

It is advisable that all measures should be takentv4QId impacts to groundwater and
surface water above the water quality standards. If impacts are documented in the future,
you would be subject to surface water regulations (15A NCAC 0213.0200) and/or
groundwater regulations (15A NCAC 02B .0202) and would be responsible for the
assessment and mitigation of those impacts. Any violations of water quality standards
could result in enforcement actions. In order to remain in compliance, the Division
supports the recommendations of your consultant, which include the protective earthen
berm, the staff gauge, and the development of a contingency plan for excess rainwater.

RE: Andy Oxy Co. Inc, SW Permit Application Submittal Request for Extension and Extension
Granted
Laura,
Thank you
At the end of January, we began removing the lime from the dry basin and also constructed a berm to prevent stormwater
from the lime storage area from entering the stormwater pipe at the edge of the pavement. We will maintain this berm
during the assessment and cleanup phases of the project, and will evaluate the possibility of a no -discharge condition in the
future.
Thanks again

Laura,
As discussed, AndyOxy hereby requests a 90-day extension for submittal of an NPDES stormwater individual permit
application for our facility on Heritage Drive in Asheville. As you know we are in the process of assessing and modifying our
lime storage area in response to requests from the NCDENR Department of Water Quality. We are currently arranging for
the assessment work which will include NCDENR DWQ field involvement. As directed by DWQ the cleanup plan will not be
implemented until after the assessment is complete. As such, collection of stormwater samples at this time would not be
representative of the typical site conditions going forward.
Also, we are unsure of the above regulatory implications on our unique industrial process. If the regulatory implications
make if financially unfeasible to continue with the operations, we might be forced to consider terminating the operation. We

have provided DWQ with informatir , other much larger operations similar tr -s that are allowed in other states, and
we are more than willing to work w. .NQ in developing a mutually -agreeable Jon going forward. However, if we are
forced to terminate the operation, the remaining activities at the facility are retail sales only which would not require a
stormwater permit. Therefore, we are requesting the extension to be able to evaluate the results of the assessment,
proceed with the cleanup, and determine if the cost of compliance with the regulations leaves the operation financially
feasible.
Thank you for your consideration as we work towards a common goal.

Brett:
understand you had a conversation with Matt Wallace today. I know we are on a timeline to get a response to the
items in your letter dated January 5, 2015.
As reported in an earlier e-mail, Matt is working with us to formalize a plan to assess the items you listed in the
letter. I understand he has had a phone call with you for clarification on a number of items. Matt is formulating a plan to
assess the groundwater and storm water outfall.
We have contacted many of our customers who we sell the lime to. We will begin moving the lime to the
customers starting Wednesday, January 28, 2015.
Carbide Industries, LLC, the producer of Calcium Carbide, was here yesterday. We discussed the issues at
hand. They are going to make their environmental engineer on staff available to us for any needs. They are also providing
us our annual usage of calcium carbide. We can then tell how much lime we produce in a year,
Matt mentioned meeting here again on Thursday, January 29, 2015 at 10:00 am. We are open to meeting on that
day/time
Andy Oxy is moving forward to meet the items listed. I trust this e-mail and others before this one meet the
required responses time line. We are diligently working to assess the issues at hand.

NOV-2014-OP-0007 (Incident #201401886)
Land application of industrial wastewater residuals without a permit
Andy Oxy Co. Inc.
Buncombe County, NC
Dear Mr. Lovin:
On November 5, 2014, Brett Laverty of the North Carolina Division of Water Resources
conducted.a site inspection of the Andy Oxy faciligy at 27 Heritage Drive in Buncombe
County. The purpose of the inspection was to investigate a complaint concerning the off -
site migration of industrial wastewater residuals.
The nature of the complaint and the resulting violation centers on your acetylene
production facility. Acetylene gas is produced almost daily by mixing water and calcium
carbide in a reaction tank. Once the reaction is complete, water and calcium hydroxide are
discharged as wastewater to an unlined earthen lagoon located in the back of the acetylene
manufacturing building. Once dewatered, the calcium hydroxide is moved to an adjacent
earthen lagoon to await distribution as a seasonal agricultural soil amendment. According
to you, the lagoons have been in operation since the early 1970's.
The topography directly behind the lagoons is steeply dipping towards an unnamed
tributary to Smith Mill Creek; a class C surface water. Calcium hydroxide was observed
outside the lagoon containment area and is currently migrating down the hillside towards
the unnamed tributary. Calcium hydroxide was also observed near the tributary and
immediately below a stormwater pipe. The inlet for the storm water pipe is located
approximately 25 feet from the lagoons. A buildup of calcium hydroxide at the pipe's inlet
indicates material is migrating off -site during precipitation events.
Other findings of the inspection include the presence of an unknown quantity of calcium
carbide on the ground directly below a dock where the (calcium carbide) flo-bin containers

Phone; 828-296-45001 Internet; www,ncdenr.gov
An Equal Opportunity 1 Affirmative Action Employer— Made in part by recycled paper

are off-loaded. This dock area is located approximately 70 feet from the above -mentioned
stormwater pipe. It is presumed that any calcium carbide mobilized by, precipitation will
migrate off -site via this stormwater pipe.
Calcium hydroxide is a highly alkaline and soluble material capable of generating a pH
value greater than 11. A pH value outside that range of 6.0 to 9.0 constitutes a violation of
both -surface and groundwater standards. There is ample evidence that episodic discharges
of calcium hydroxide and calcium carbide are reaching nearby surface waters. Given the
length of time the lagoons have been in operation, there are serious concerns that the
underlying groundwater quality may be impacted.
Violations
As a result of the site inspection the following violations are noted:
(1) Discharging to Waters of the State Without a Permit
(2) Operating a Disposal System Without a Permit.
Item 1. Discharge Without Valid Permit
G.S.143-215.1 (a) - No person shall do any of the following things or carry out any of the
following activities unless that person has received a permit from the Commission and has
complied with all conditions set forth in the permit:
(1) Make any outlets into the waters of the State
Item II. Operating a Disposal System Without a Valid Permit
G.S. 143-21.5.1(a) - No person shall do any of the following things or carry out any of the
following activities unless that person has received a permit from the Commission and has
complied with all conditions set forth in the permit:
(2) Construct or operate any sewer system, treatment works, or disposal system within the
S to te.
Required Response
This Office requests that you respond to this letter in writing within 15 days of receipt of
this Notice. Your response should be sent to this Office at the letterhead address. Your
response should address the following items:
1. Immediately secure all waste materials and eliminate any off -site movement of
calcium hydroxide and calcium carbide.
2. Please submit a work plan to assess the volume and extent of the release(s). In
this report, provide a map showing the extent of materials near the unnamed
tributary.
3. Please submit a cleanup plan for the affected areas.
4. Estimate the amount of calcium hydroxide currently being stored on -site, the
amount produced annually and the total estimate waste material'remaining at
the site (including all areas where the waste is present).
5. Provide a scope work and timetable to assess the quality of groundwater in the

1�
vicinity of the lagoons.
6. Provide a scope of work and timetable for the removal and cleanup of the
lagoons
Thank you for your attention to this matter. You may want to retain the services of an
engineering consulting firm to evaluate wastewater and waste management options for
this facility to bring the operation into compliance with applicable regulations. This office
requires that the violations, as detailed above, be abated immediately and properly
resolved. Thank you for your attention to this matter. This Office is considering sending a
recommendation for enforcement to the Director of the Division of Water Resources
regarding these issues and any future/continued violations that may be encountered. Your
above -mentioned response to this correspondence will be considered in this process.
These violations and any future violations are subject to civil penalty assessments.
The violations are subject to civil penalties up to $25,000.00 per day for each
violation as per G.S.143-215.6A(a)(2). Should you have any questions regarding these
matters, please contact me at [phone].

Dear Mr. Lovin:
This letter is in follow-up to the NPDES Stormwater inspection conducted on November
5, 2014 at the Andy Oxy Co., Inc. Asheville facility. Brett Laverty (Division of Water
Resources), Darlene Kucken, and I appreciate your assistance while conducting the
inspection. A review of our findings during the inspection indicates that an NPDES
individual permit is required. Note that during our inspection we observed at least two
stormwater outfails from the facility that convey stormwater from the property to a
drainage area and stream. You are requested to complete the attached application
and to submit to our Stormwater Section in Raleigh at the following address by January
31, 2015: NCDENR; DEMLR — Stormwater Permitting Program; 1612 Mail Service
Center; Raleigh, NC 27699-1612. If you prefer you can complete this application on-

As we discussed on site, efforts should be made to limit stormwater exposure to any
process pollutants. A Stormwater Pollution Prevention Plan (SWPPP) and stormwater
outfall monitoring will be required as part of the permit requirements.

Ken and Bethany,
See the below info regarding the process at Andy Oxy and the results of the pH bench test. I've canvassed a couple of
other regions to see if they have any similar manufacturers to no avail. Also see attached the photos of the site. If you
have some time next week, I would like to discuss. Mike Lawyer did suggest that this might be similar to a Ready Mix
facility with the carbide lime (activated lime) slurry waste product. See attached MSDS .
Thanks,
Laura

Subject: RE: Andy Oxy Bench Test Results
Laura and Darlene,
Just a follow up to the bench test results. Kathy said her magnetized stirring pellet pick up some metal particles in the
sample. I also found some basic information on calcium carbide and the generation of acetylene gas. The summary is
given below for your reading pleasure:
Calcium carbide is a chemical compound with the chemical formula of CaC2. Its main use
industrially is in the production of acetylene and calcium cyanamide. The pure material is
colorless, however pieces of technical -grade calcium carbide are grey or brown and consist of
about 80-85% of CaC2 (the rest is CaO (calcium oxide), Ca3P2 (calcium phosphide), Ca5

(calcium sulfide), Ca3N2 (calcium nitride), SiC (silicon carbide), etc.). In the presence of trace
moisture, technical -grade calcium carbide emits an unpleasant odor reminiscent of garlic.
Applications of calcium carbide include manufacture of acetylene gas, and for generation of
acetylene in carbide lamps; manufacturer of chemicals for fertilizer; and in steelmaking.
Calcium carbide is produced industrially in an electric arc furnace from a mixture of lime and
coke at approximately 2000'C. This method has not changed since its invention in 1888:
CaO +3 C-> CaC2 +CO
The high temperature required for this reaction is not practically achievable by traditional
combustion, so the reaction is performed in an electric arc furnace with graphite electrodes.
The carbide product produced generally contains around 80% calcium carbide by weight. The
carbide is crushed to produce small lumps that can range from a few mm up to 50 mm. The
impurities are concentrated in the finer fractions. The CaC2 content of the product is assayed
by measuring the amount of acetylene produced on hydrolysis (Britt said his product was 8%
carbide). As an example, the British and German standards for the content of the coarser
fractions are 295 L/kg and 300 L/kg respectively (at 101 kPa pressure and 20 °C temperature).
Impurities present in the carbide include phosphide, which produces phosphine when
hydrolysed.
The reaction of calcium carbide with water, producing acetylene and calcium hydroxide, was
discovered by Friedrich Wohler in 1862.

Laura and Darlene,

water and stirred for an hour. The initial pH of the deionized water was 6.1. Here are the results:

The material Andy Oxy has stored onsite is obviously soluble under natural rainfall conditions and is capable of
generating high pH's. Something to consider for your storm water permit.

Ken and Bethany,
This site manufactures acetylene (SIC 2813). The by-product, calcium carbonate, is sold as a soil amendment. Would
this be subject to an NPDES SW permit and if so under which category? I don't see a general permit that appears to fit?
Thanks,
Laura

Brett,
I have Andrea's notes where you both inspected on July 23, 2014. Did you evaluate for NPDES wastewater
applicability? Is there a release point or outlet from the pond where the calcium carbonate is placed (wastewater)? We
are planning an inspection wrt to stormwater applicability, but wanted to get an update on you on any NPDES
wastewater issues. Let's talk.
Thanks,
Laura

Laura,
I'm certain acetylene manufacture falls in the Chemical Industries category 28xx that is subject to NPDE=S. I'm not
completely sure about the soil amendment, but from our days researching compost, I'm thinking that does too... Either
way, if the main revenue (and primary process) involves acetylene manufacture, AND the site has point source discharges
of storrriwater, it is subject to an NPDES permit (regardless of whether it also makes calcium carbonate or not).
There is no general permit for SIC 28XX. We typically handle those under individual permits because the industry sector
is so broad.
Hope that answers your question!

I couldn't read the attachment at home through the webmail, but I'm looking at it now. Maybe it's the other way
around and acetylene is the by-product? I'll have to look into this more. -Bg

Jason Watkins received complaint call from Roy Borden, representative for adjacent property owner. Complaint stated that waste was
being placed across property lines (byproduct of commercial activity on site) and that liquid waste was stored in pond on site.
I
Jul 14, 2014
Andrea Keller contacted Hazardous Waste Branch to determine if they had a permit with the facility, or history on file (due to wet pond).
Spring Alien (DWM Haz Waste) stated that she remembered the site from visits in the 1990's, that samples were collected from the "pond,"
and that at that time, it was a by-product from the manufacture of Acetylene chat was then sold as fertilizer (lime). They were not
2
Jul 15, 2014
determined to be a HW generator at that time. She contacted Robin Proctor (HW chemist) as she had been the lead on the investigation.
Robin Proctor, in email, stated the following: Andrea. The area of concern in the picture is the "pond" where the calcium carbonate is
placed. This is a by-product of the production of acetylene. It is very high pH (? 13) but changes very quickly to below the levels for
hazardous waste (12.5). We collected samples responding to a complaint sometime in the 90s. The samples were below 12.5 in the pond.
3
Jul 17, 2014
Since it was not hazardous waste, the complaint was referred to water quality and the county. I have no idea if any other agency acted on it.
A. Keller checked with the county and with Water Resources to see if anything was on file. Nothing was found.
A. Keller on site with Brett Lovin and Bill Anderson (manager and owner). The material is the byproduct of producing Acetylene - the
byproducts are water and lime, It is not a machine shop. The slurry is pumped out into the "pond" and the slurry dries out and is is then
sold, They had a long-time verbal agreement with land owner (adjacent) to expand on that side of the property. They were told that a) the
4
Jul 23, 2014
property use dispute was between them and the property owner and that I would put them in touch, that b) this did not appear to be a Haz
0
Waste or Solid Waste issue, and c) that I would be referring this to Land Resources, Industrial stormwaterlwastewater program for further
evaluation.
A. Keller sent email to Roy Borden (rep. for property owner) and Britt Lovin (rep for business owner/generator) to explain the referral to
Land Resources.

Completed IS - referred to Land Resources (had discussed site with them in advance of the referral)

Andrea Keller contacted Hazardous Waste Branch to determine if they had a permit with the facility, or history on file (due to wet pond).
Spring Allen (DWM Haz Waste) stated that she remembered the site from visits in the 1990's, that samples were collected from the "pond,"
and that ac that time, it was a by-product from the manufacture of Acetylene that was then sold as fertilizer (lime). They were not

Robin Proctor, in email, stated the following: Andrea. The area of concern in the picture is the "pond" where the calcium carbonate is
placed, This is a by-product of the production of acetylene. it is very high pH (>13) but changes very quickly to below the levels for
hazardous waste (12.5). We collected samples responding to a complaint sometime in the 90s. The samples were below 12.5 in the pond.

Since it was not hazardous waste, the complaint was referred to water quality and the county. I have no idea it any other agency acted on it.
A. Keller checked with the county and with Water Resources to see if anything was on file. Nothing was found.
A. Keller on site with Brett Lovin and Bill Anderson (manager and owner), The material is the byproduct of producing Acetylene - the
byproducts are water and lime. It is not a machine shop, The slurry is pumped out into the "pond" and the slurry dries out and is is then
said. They had a long-time verbal agreement with land owner (adjacent) to expand on that side of the property, They were told that a) the

CARBIDE LIME
DESCRIPTION Carbide limed s by-product calcium hydrate formed by the reactionef water
with calcium carbide in the generation of acetylene. It also is known
as carbide sludge, generator slurry, lime sludge, hydrated lime, etc. It is a poten-
tial top grade hydrated lime because of the high quality of the original raw materials
used in manufacturing calcium carbide and the nature of the electric :urnacing and ace-
tylene generation steps through which it passes.
AVAILABILITY In general, carbide lime is available wherever calcium carbide is used
for generation of acetylene. Since this practice is widely followed in
almost all parts of the country, it follows that carbide lime is available throughout
practically all industrial and agricultural areas. Classified sections of local tele-
phone directories usually list producers or merchandizers of "acetylene" who normally
are in a position to advise where carbide lime can be obtained.
CHEMICAL A typical analysis of dried carbide lime, taken from a generator slurry
C014POSITION settling pit, follows;
Calcium Oxide 70.90 per cent
Combined Water 23.69 "
Carbon Dioxide 1.03
Iron and Aluminum Oxides 1.55

SOLIDS COIITEHT The usual solids concentration of the slurry from "wet generation" is
AND DRYING from 10 to 12 per cent, It is possible to concentrate slurry to about
30 to 40 per cent solids by decanting or by the use of a thickener and
to about 45 to 55 per cent solids by delayed pond settling. in at centrifuge the slurry
can be concentrated satisfactorily up to 60 per cent solids. Drying of the 60 per cent
solids to a moisture content of 1 to 3 per cent can be accomplished in a flash drier
without excessive carbonate.formation.

COLOR, ODOR AND Since carbide lime is a by-product, slight variations in chemical
FOREICH IIATERIALS analysisand presence of alien matter will exist, depending in local
conditions at point of production. As it comes from the generator,
carbide line has a grayish color and a characteristic acetylenic odor. The grayish
color results largely from the very small percentage of combined sulphur contained in
the slurry. The odor passes away with time. Small amounts of ferro-silicon, carbon,
and other impurities also are contained in the slurry.
Only a trace of magnesium is present in carbide lime because the lime originally used
in making calcium carbide must be extremely low in magnesium. Low magnesium and high
calcium contents are especially necessary in most chemical uses of lime because the re-
ulting magnesium products dissolve very easily in pater, while calcium products are
soluble and can be removed easily by precipitation.
PARTICLE SIZE Carbide lime is extremely fine in particle size, comparable to and.us-
ually finer than most commercial hydrated limes. It is completely hy-
drated, that is, free from unslaked line, because it is made in many times its own
weight of water. Ordinary hydrated lime is made with only a fraction of its own.voigyt
of crater In order to avoid subsequent drying which is inconvenient and expensive.
In one test of dried carbide lime, 99.9 per cent passed through a 300-riesh sieve. In
another series of tests, 92 to 98 per cent passed tbrough a 325-mesh screen. This ex-
treme fineness is caused by the process of "stet generation.' The acetylene, while
liberating itself from the calcium carbide, cracks'or breaks open ordinary fine grains
of lime into still finer particles. The heat and excess crater in the generator also
present ideal conditions for the production of very fine particles of hydrated live.
Ordinary commercial hydrated lime does not show as high a percentage as the above passed
through a 200-mesh screen. Conspicuous advantages of carbide lisle. due to its finer
particles. are quicker and more efficient action and the smaller quantity required than
when using ordinary hydrated lime.
— ft fliESS VS- -Despite the eztrcuie fineness of particle size of carbide lime, the solids
SETTLING of a residue slurry generally settle many times faster than the solids of
a water -lime mixture made directly from burned lime, on e-_nth"and.,
uhere fast may De overcome by grinding the wet carbide lime
in a colloid mill. Residue slurry, treated in this manger, can be Feld in tank storage
for a week or more without appreciable settling. In addition, it is less apt to clog
valves or lines of a pumping system.
IIIDtIIIG MID Carbide lime with a solids content in the range of 45 to 60 per cent is
11IIPIIIG amenable to digGine and truck hauling. Slurries of lesser solids content r
are hauled by tank truck or car satisfactorily. Pumping of carbide lime
pis feasible in solids content up to G0 per cent. It bas been shown to be economically
feasible and practical to load and ship carbide lime by river barges in relatively large
tonnages. The use of a drat line scraper for pond live reclamation has proven success-

One method of reclaiming lime from ponds is to slurry the pond solids with water to
about 25 per cent solids content and pump the latter to an agitated storage tank for
loading out to tank trucks or cars, .Another method is to pump slurries of from 10 to
12 per cent solids content into tank cars and by a process of progressive decantation,
increase the solids content to about 30 per cent or better, prior to the start of the
transportation haul, to reduce the gross volume per unit of solids,

.+OIL CONDIT]01111.0 Lime is applied to land extensively in the form of hydrated lime
and limestone for: (1) neutralizing soil acidity;(2) replenishing
calcium supply (3) promoting activity of beneficial bacteria and depressing injurious
soil organisms; (d) improving soil texture or tilth; (5) hastening organic matter decay
and nitrate formation; (6) killing certain soil -borne plant disease organisms. By-product
carbide lime, or carbide residue, is a Satisfactory liming agent and is not difficult
to distribute oi, the land when sufficiently dry,
The quantity cf carbide lime that should be used depends on whether the soil is mild,,
medium or strongly acid. A farmer or gafdene.r always can secure dependable informa-
tion as to the quantity of carbide lime his particular soil will require by having it
analyzed by properly qualified consultants or Federal Farm Bureau representatives. Acid
soil is encountered in most lawns, and moderate treatment with carbide lime produces
beneficial results.
IIISECTICIDES, FUNGICIDES, Lime enters many. insecticides, fungicides and disinfectants
DISINFECTANTS used for spraying crops, trees, gardens and buildings. Dry,
or as a whitewash, it also is used r.s a mild disinfectant.
Lime sulphur, one of the best fungicides for trees, is prepared by heating sulphur with
milk of lime. In whitewash form, lime long has been recognized for its ability to mi-
tigate the common undesirable odors about farm and dairy buildings.
Carbide lime, because of the traces of sulphur, phosphorus and other chemical elements
which it.contains, possesses properties which make it equally as good as ordinary slaked
lime for the foregoing purposes, For example, it may be used advantageously in the
preparation of spraying solutions, including those carrying sulphur, calcium or lead
senate, Paris Green, or other chemicals. The lime, among other things, serves as an
ahesive agent, assisting in keeping the poison on the vegetation, Care must be exer-
cised that the carbide lime does not contain particles sufficiently large to clog spray
nozzles.
Carbide lime dust has been found excellent for chickens to wallow in and rid themselves
of lice. in a dry powdered state, carbide lime dusted on potato plants, currant bushes
and other growths, has proven effective in banishing ravishing insects.
CKEAICAL REAGENT Lime is one of the most widely used chemical re -agents and enters
directly into the manufacture of hundreds of articles. Bleaching
powder or bleaching solution is made from slaked lime, or milk of lime, and chlorine.
Milk of lime is used as a dechlorinating agent in the manufacture of trichloroethylene,
ethylene glycol, and other organic chemicals. Sy -product carbide lime is always a po-
tential source of high -calcium lime for those uses because of its high reactivity a,ld
fine particle size.
INDUSTRIAL In the pulp and paper industries, lime, or lime and soda ash, is used
APPLICATIONS for cooking rags used in paper manufacture, in a digester under steam
pressure. hydrated .lime is used for. the recovery of, ammonla in by-product
coke plants. In the leather industry, lime is used in the depilation (hair removing)
Process. The skins are soaked in vats containing milk of lime, arsenic sulphide, sodium
sulphide and. sometimes. sod ium._ vd_toxid ._. She lime shauLd—contaia. a ainimum-o f_ga—pe.r
cent Cab, and have a low amount of iron. Paint and'varrtish manufacture requires the
use of lime to neutralize the acids and clarify varnishes, and as a resinate in -paints.
Refinery gases are washed with milk of lime for the removal of various forms of sulphur
and the diminution of the latter's cgrrosive effect on equipment. By-product carbide
lime is suitable for all these purposes.
mETALLURGICAL Lime is used in.connection with the concentration of ore minerals in k
APPLICATIO}iS flotation processes where it serves several parpoies. In fIotat'io�:a

or caustic under certain conditions. Lime is used rather extensively in the cyanide
process. In iron and steel making, lime, hydrated lime, o'r milk of lime is employed to
neutralize waste pickling acids before they are discharged into rivers and streams.
Foundry molds are sprayed or dipped with milk of lime to prevent sticking of the metal
to the mold. In wire drawing, the coils of wire are diplped into milk of lime to neu-
tralize the remaining pickling acid and to serve as a lubricant in the drawing process.
The lime must be absolutely free of grit, By-product carbide lime has been used for
many of the foregoing applications,
VATER SOFTE111UG Lime, or a mixture of lime and soda ash, is used extensively for
softening water, When water contains considerable quantities of the
bicarbonates and sulphates of calcium and magnesium, it is hard. The bicarbonates
produce what is termed "temporary hardness," When excess Mime is added, the bicarbonates
form carbonates that are much less soluble in water, and a precipitate is created which
is removed by filtration. Carbide lime can be substituted for all or part of the line
employed for this operation.
SEIfAGE TREATMENT Ferric chloride and quicklime are added at one point in the sewage
treatment process to form a coagulant to facilitate dewatering of
the sewage sludge. Carbide lime has been used to replace the quicklime with success.
It is equally effective and is already hydrated, whereas the quicklime must be hydrated
before using. Considerable savings have been realized 1y using carbide lime in place
of quicklime for sewage treatment.
SUILDIIIG ACID Quicklime and hydrated lime are used in Clue building industry, Quicklime
COBSTRUCTIO)i must be made into a putty by proper slakimg and hydrated lime should be -
soaked before.usine. Physical properties of the hydrate, such as plas-
ticity, sand -carrying capacity, strength when mixed with sand, time of set, and color,
are important to consider for building uses. Lime (or hydrate) for mortar, plaster and
masonry must meet or exceed the following chemical requirements:
Ca0, min. 75 per cent
CaO plus MgO, min. 95 " "
Silica. Iron. etc.. max. 5 " "
CO2 content, max. 10 "
The sample shall leave a residue of 0.5 per cent maximum on a 30-mesh sieve and 15 per
cent maximum on a 200-mesh sieve. Carbide lime will meet the above specifications ex-
cept, perhaps, where color is important. The slurry, of course, must be concentrated
to about 55 per cent solids, or greater, for use in mortars and cements. otherwise, the
mix will contain too much water.
Lime mortar is made by mixing lime putty with sand and water. The substitution of car-
bide lime for the lime in straight lime mortar or lime -.cement mortar has proven com-
pletely successful in a large amount of construction work countrywide. Because of its
complete hydration and extreme fineness,' mortar made with carbide lime spreads more
— s" othly'with-less effort and has as much "pull" to it as the average grade of high
magnesium hydrated lime. In addition, it resists wea'theu conditions better. Special

factor. The plasticity, or spreading quality of plaster made with carbide lime, is said
to be superior to that of plaster made tiTith ordinary hydrated lime. It works more
smoothly under the trowel and is said not to "buckle" or "pit.' A coarse sand or small
aggregate is used for outside stucco work.
Concrete has its plasticity, workability and resistance to water absorpticn increased
by the addition of hydrated lime. The latter is added to the batch as it goes to the
mixer. ;lydrated lime also prevents segregation or unmixing of concrete, eliminates
stone pockets or honeycombing and makes the concrete denser: It reduces placing andfin-
ishing costs. Carbide lime serves as an excellent substitute for hydrated lime for this
purpose.
BRICK Silica brick, which is used chiefly for furnace linings, requires large ton-
nages of lime in its manufacture. Milk of lime is added to silica in quanti-
ties ranging from 1.5 to 4 per cent CaO. The mixture is,molded and burned under care-
fully controlled conditions.
Sand -lime brick is made by mixing sand and carbide lime, pressing the brick into form
and treating it under high steam pressure. The lime must be hydrated completely before
the mizt.ure is pressed, otherwise subsequent hydration will cause expansion and rupture
of the brick.
Cinder brick is a special type of clinker brick which is made by a patented process from
prepared volcanic ash or cinders and hydrated lime.
rbide lime 'can be substituted for hydrated lime in making any of the above types of
.ck. Also, new brick furnace arches that have been given a coating of carbide lime
thinned with water to the consistency of molasses, have been found to glaze perfectly

PIPE LIMES pletely .around an underground steel pipe line, will protect the pipe line
from possible corrosive attack, due to acid soil or similar conditions,
and aid in postponing leaks, maintenance and replacement of the pipe line.
FE)iCE POSTS A gallon or two of, carbide lime slurry, poured around fence posts when
setting them will prevent decay. The slurry should be strongest in the
surface layer of earth.
STABILIZATIOil OF Many hard -surfaced roads have been built on clay roadbeds. During
CLAY ROADBEDS therainy seasons, the clay underneath the road surface absorbs water
and becomes very soft and begins to swell. Then, in the summer, the
clay dries out to some extent and the road base begins to sink. As a result, the road
surface becomes broken and rough. The treatment of soils to produce a good road base
—is.-known as soil stabilization. -Recent laboratory investigations indicate -that -hydrated
lime is best for stabilizing heavy or sticky clays.
n preparing a road base or s aEi-ITzing, the sofl—usua7lyis plowed to a depth of six
to eight inches. The clods are broken up as finely as possible with a disp before the
lime is spread. To obtain the best results in mixing, the soil should be dry. Sacks
of hydrated lime are distributed along the road, spaced so as to provide the proper
amount of lime per square yard.
,..e clay is mixed thoroughly with the proper amount of lime and water. The water is'�
added by means of the usual type of water sprinkler. As the water is absorbed by the
clods, it carries the lime with it. The clay becomes as friable as sandy soil. This
Is a very desirable feature of clay soil. stabilized with lime.

The Manufacturing
Process
There are two basic conversion processes used to make acetylene. One is a chemical
reaction process, which occurs at normal temperatures. The other is a thermal cracking
process, which occurs at extremely high temperatures.
Here are typical sequences of operations used to convert various raw materials into
acetylene by each of the two basic processes. ICA
y S
Chemical reaction process
Acetylene may be generated by the chemical reaction between calcium carbide and
water. This reaction produces a considerable amount of heat, which must be removed to
prevent the acetylene gas from exploding. There are several variations of this process in
which either calcium carbide is added to water or water is added to calcium carbide.
Both of these variations are called wet processes because an excess amount of water is
used to absorb the heat of the reaction. A third variation, called a dry process, uses only
a limited amount of water, which then evaporates as it absorbs the heat. -The first
variation is most commonly used in the United States and is described below.
i. Most high -capacity acetylene generators use a rotating screw conveyor to feed
calcium carbide granules into the reaction chamber, which has been filled to a
certain level with water. The granules measure about o.o8 in x o.25 in (2 mm x b
mm), which provides the right amount of exposed surfaces to allow a complete
o
reaction. The feed rate is determined by the desired rate of gas flow and is
controlled by a pressure switch in the chamber. If too much gas is being produced
at one time, the pressure switch opens and cuts back the feed rate.
2. To ensure a complete reaction, the solution of calcium carbide granules and
water is constantly agitated by a set of rotating paddles inside the reaction

chamber. This also prevents any granules from floating on the surface where they
could over -heat and ignite the acetylene
3. The acetylene gas bubbles to the surface and is drawn off under low pressure. As
it leaves the reaction chamber, the gas is cooled by a spray of water. This water
spray also adds water to the reaction chamber to keep the reaction going as new
calcium carbide is added. After the gas is cooled, it passes through a flash
arrester, which prevents any accidental ignition from equipment downstream of
the chamber.
4. As the calcium carbide reacts with the water, it forms a slurry of calcium?
cr arbonate, which sinks to the bottom of the chamber. Periodically the reaction
must be stopped to remove the built-up slurry. The

COMMERCIAL LIME AND CARBIDE LIME
Existing forms of commercial lime fall into the following categories:
Limestone - calcium carbonate (CaCO3)
Quicklime, pebble, burnt, hot, or lump lime - calcium oxide (CaO)
Dolomitic quicklime - a mix of calcium oxide (CaO) and
magnesium oxide (MgO)
Dolomitic hydrated lime - a compound mixture of calcium
hydroxide (Ca(OH)Z) and magnesium hydroxide (Mg(OH)2
Hydrated lime - calcium hydroxide (Ca(OH)z)
CARBIDE LIME FALLS INTO THE HYDRATED LIME CATEGORY

UANTITY OF CARBIDE LIME PRODUCED BY A TYPICAL ACETYLENE PLANT
Carbide lime, Ca(OH)2, is a product of the reaction of calcium carbide, CaC, with water,
H2O, during the generation of acetylene.
When calcium carbide and water are combined, the following reactions take place in the
acetylene generator:
CaC2 + 2H20 CH, 1 + Ca OH
calcium carbide + water acetylene + carbide lime
CaO + H2O Ca OH
calcium oxide + water carbide lime
By using the above reaction, it can be shown that one ton of calcium carbide generated into
acetylene will produce approximately 1.18 tons of carbide lime.
The carbide lime will contain approximately 70.01 % available calcium oxide (CaO).
The following example shows how to determine the amount of available calcium oxide in
a given volume of carbide lime slurry:
ASSUMPTIONS
1. 4,000 gallons of 25% solids carbide lime slurry,
density 9.6 lbslgal (pg. 7).
2. Carbide lime contains 70.01 % available calcium oxide
(CaO) (dry basis).

Because of its fine particle size (90% through 325 mesh) and low magnesium content,
carbide lime is very fast reacting. The available calcium oxide content is the yardstick by
which the effectiveness, reactivity, or neutralizing value of lime is measured for most uses.
Carbide limes grayish color is due to the presence of small amounts of finely divided carbon
and ferrosilicon -- natural impurities in calcium carbide lime. These properties do not limit
the usefulness of carbide lime but serve only to distinguish carbide lime from other sources
of lime.

operators of similar systems have provided the following "tips" for a smooth
operation:
1. Screening the carbide lime as it enters the pit prevents foreign matter from
entering the pump.
2. Pipelines should be slightly pitehes to permit self -draining.
3. 3" diameter pipes, hoses, fittings... etc., are preferred for the handling of the
carbide lime.
4. Some pumps that have been used to satisfactorily move carbide lime of up to
40% solids are:

POTENTIAL USES OF CARBIDE LIME
STEEL AND METAL WORKING
Waste pickling acid neutralization - Most waste pickling liquors contain either 4 - 7% sulfuric or
hydrochloric acid and 14 - 15% iron salt as either ferrous sulfate or ferrous chloride. Low cost
carbide lime slurry is ideal for neutralizing these pickling acids.
Recovery of ammonia in coke plants - Coke oven volatiles contain ammonia which is removed by
contact with carbide lime slurry in a stripping tower. The recovered ammonia is saturated with
sulfuric acid to give ammonium sulfate which is sold as fertilizer.
Coating lubricant - Carbide lime slurry acts as a coating lubricant for pig iron molds and cinder pots.
Water softener for chemical water and boiler water treatment - Carbide lime slurry precipitates the
calcium and magnesium bicarbonate hardness for removal by filtration.
SEWAGE DISPOSAL PLANTS
Carbide lime slurry and ferric chloride act as coagulants to facilitate de -watering of the sewage solids
or "sludge" on vacuum filters; this is generally known as the Guggenheim System for Sewage
Treatment.
CHEMICAL
Chemical reagent - Carbide lime's high calcium oxide content and fine particle size contributes high
reactivity and is, therefore, an ideal reagent for many chemical processes.
Dehalogenation - Carbide lime is used in manufacturing trichloroethylene. Production of ethylene
oxide, ethylene glycol, propylene oxide, propylene glycol, and other organic chemicals also make
use of carbide lime.
Neutralization of various wastes - For example, wastes such as acids, phenol, fluorine, dyes, etc. are
neutralized with carbide lime.
PULP AND PAPER
Causticizing agent - Carbide lime is very effective for converting the sodium carbonate in the spent
black liquor to sodium hydroxide as part of the recovered white liquor.
Bleaching pulp - Carbide lime slurry reacts with chlorine to form calcium hypochlorite, a bleaching
agent for pulp.
7

BUILDING AND CONSTRUCTION
Manufacture of brick - Carbide lime is mixed with sand and placed in autoclaves under high steam
pressure to form a sand -lime brick of top quality comparable in physical properties and cost to clay
brick. Cinder or clinker brick has also been economically made with carbide lime.
Pozzolanic clay -soil road bed stabilization - By using 8 parts of The C/G Group's lime (dry basis)
to 92 parts of soil, the stabilization of road beds in highway construction is achieved.
MASONRY CEMENT
Carbide lime has been used advantageously in commercial practice for a masonry cement mix
containing three parts carbide lime (50% solids), three parts cement and seven parts sand.
LEATHER -TANNING
Debilitant or hair removing agent - Another application is in the paddle vats for dehairing hides or
skins in the tanning industry. A saturated lime solution along with a small amount of sodium sulfide
produced the desired effect.
ACID MINE DRAINAGE TREATMENT
Carbide lime neutralizes acidic mine drainage and precipitates out its ugly brown color (ferric
sulfate).
AGRICULTURE
Antiseptic or germicide - Carbide lime is an ideal whitewash material for interiors of poultry
buildings and for many other purposes around the farm.
Neutralization of soil acidity - Either as dry or as concentrated slurry, carbide lime can be
mechanically distributed successfully on farm land for neutralization of soil acidity.
Additional Applications for carbide lime are given in the Compressed Gas Association pamphlet G-
1.5 entitled "Carbide Lime: Its Value and Its Uses,"

SAFETY
Eye and skin irritation may result from contact with carbide lime unless treatment is
administered quickly. Strict first aid procedures should be followed:
A. Eve contact - Clean around eyes using boric acid solution (1:1000 - see (C) below),
turn back eyelid and, using sterile cotton swab, clean carbide lime out of eye. Flush
with boric acid solution for 5 to 15 minutes. If blisters are apparent, use ice packs
for 20 to 30 minutes, then apply 0.5% Gantrisin Ophthalmic Ointment - Q.I.D. (4
times daily). See a physician.
B. Skin contact - Wash skin with vinegar to neutralize. Vinegar has a 4% acid base and,
like boric acid solution, serves as a neutralizer for carbide lime. Vinegar should be
used first when dealing with carbide lime contact on the skin. Oiling of the skin
where exposed to carbide lime is then recommended. The oil may be coconut,
Vaseline, or other skin lubricants. If oil is not used, skin cracks may develop, leading
to possible infection.
C. Directions for boric acid solution Q-1000) - Mix together 1 teaspoon boric acid
powder to 1 pint distilled water. Boil until crystal clear. Keep in closed container
and away from light.

in nitrogen. If acetylene concentration is more than
0.6% (25% L.E.L.), restart nitrogen flow and repeat
procedure 5. Remove tubing and close port valve.
7. When acetylene concentration is less than 0.6%
(25% L.E.L.), the nitrogen flow rate can be reduced
unfit the container is needed for production.
8. When container is to be used and is already posi-
tioned on the support stand or in a property gas-
keted dispensing unit, proceed to `Discharging
Calcium Carbide from Container.'
Discharging Calcium
Carbide from Containers
1. Set containers on unloading stand or on properly
gasketed dispensing unit.
2. Attach suitable grounding cable to container,
WARNING: Do not use copper cable.
3. Remove cap from vertical purge outlet pipe and
connect 3/4-inch minimum purge exhaust hose
thereto. Vent exhaust outside building away from
ignition sources. (See schematic.)
Caution: Step (3) must be done prior to step (4).
Excessive nitrogen pressure will distort
container.
4. Remove cap from horizontal purge inlet pipe and
connect dry nitrogen hose with regulator, flow -
meter, check valve and 5 PSIG relief valve. (See
schematic.)
5. Set regulator at 3 PSIG, maximum, and purge
container with at least 60 SCF nitrogen. (See
schematic.)
6. Move gate to OPEN position. Flow of calcium
carbide should be controlled only by dispenser unit
apparatus, since bottom gates are not designed for
regulating rate of discharge.
7. Avoid spilling calcium carbide in work area. All
spilled calcium carbide must be cleaned up and
used immediately or removed to an outdoor posted
isolated area, away from buildings, open flames, or
other sources of ignition. Do not allow carbide to
accumulate in piles. In the event of significant
spills, contact your supplier.

Handling Empty Containers
1. When container is considered empty, tap the sides
with rubber/wood mallet to make sure all carbide
has been removed.
Caution: Small amounts of carbide retained
within a closed vessel will be exposed to a dis-
proportional amount of moist air. The carbide is
then more susceptible to acetylene generation
and the resultant explosion hazards.
2. Close bottom gate. Inspect gaskets at gate. Re-
place worn or missing gaskets. Reclose and lock
bottom gate.
3. Test purge exhaust for acetylene. Purging can be
discontinued when acetylene concentration is
below 0.6% (250/6 L.E.L.).
4. Turn off nitrogen flow, disconnect purge and
exhaust -pipe hoses. Recap container purge and
exhaust pipes and disconnect grounding cable.
5. Remove container from dispensing unit.
6. Top cover must be tightly closed.
7. Transport empty container to a proper storage
area.

Shipping Inspection
All calcium carbide containers being returned to suppli-
er must be inspected prior to loading on any transporta-
tion vehicle or railroad Car.
1. Top covers must be tightly closed.
2. Body of containers must be examined for bulges,
open seams or other evidence of in -plant handling
damage which might affect water -tightness.
3. Purge lines must be securely capped.
4. Bottom gates must be completely closed and
locked in place.
Any container failing to meet these conditions must be
immediately removed to a dry and isolated area, away
from all sources of ignition. Container must be covered
to prevent water entry. Contact supplier immediately for
specific handling instructions.
Elkem-American Carbide assumes no liability in con-
nection with the handling, storing, discharging or
any other use of any container, or application of
procedures as set forth herein.
