Dear Sir,
Sub: Setting up of Chemplast PVC plant in SIPCOT, Cuddalore
This is with respect to the setting up of a PVC plant by Chemplast
in the SIPCOT Industrial Estate in Cuddalore. The plant uses VCM
as the raw material to manufacture PVC resin.
Research worldwide has shown that PVC is a poison plastic that
has environment and health impacts right from production, through
use and disposal. Countries in the West have adopted various restrictions
on the manufacture, use and disposal of PVC and are moving towards
a phase-out while India seems to be encouraging its production.
It is also shown that the manufacture of PVC uses a deadly raw
material Vinyl Chloride Monomer (VCM). VCM is a highly flammable
chemical and is capable of causing serious chemical accidents.
It is cancer-causing and also capable of causing severe reproductive
and developmental disorders. Workers of PVC plants and communities
living around such plants are constantly exposed.
(Please refer enclosure on the hazards of VCM)
Further, the Supreme Court High-Powered Committee on Hazardous
Waste has made recommendations to avoid POPs generating processes.
India has also just agreed to sign the International Convention
on Persistent Organic Pollutants (POPs) to reduce generation of
these toxic substances. PVC facilities are proven to release Dioxin
(a POP chemical) and setting up of this plant means violating
the Convention.
Considering the facts, we strongly urge you not to allow this
environmentally disastrous plant to be set-up. Sincerely
Rajesh Rangarajan

2. Regulations that the PVC plant violates
VINYL CHLORIDE (or) VINYL CHLORIDE MONOMER (VCM) A
Profile
Characteristics
Vinyl chloride monomer is reactive; it will polymerise in light,
air or heat, unless stabilised with inhibitors. It is soluble
in many organic solvents, but only slightly soluble in water.
As a gas, mixed with air, vinyl chloride is a fire and explosion
hazard. On standing, it can produce peroxides, which may then
explode1. Vinyl Chloride is released to the environment as emissions
and wastewater at polyvinyl chloride (PVC) plastics production
and manufacturing facilities2.
Hazardous nature
The USEPA has listed hazardous, the wastes generated by chlorinated
aliphatic industry, especially - wastewater treatment sludge from
the production of Ethylene Dichloride / Vinyl Chloride Monomer3.
Toxicity
The inhalation of high levels of vinyl chloride has led to narcosis
(the effects of a narcotic drug), problems in breathing, convulsions
and death. At lower levels, symptoms may be headaches, and dizziness.
Long-term exposure may cause impotence, blood disorders, and liver
problems. The International Agency for Research on Cancer has
classified vinyl chloride as a human carcinogen, based upon evidence
of carcinogenicity in both humans and animals4.
CARCINOGENICITY5
Vinyl chloride is known to be a human carcinogen based on sufficient
evidence of carcinogenicity in humans. Vinyl chloride has been
associated with tumours of the liver, brain, lung, and hematolymphopoietic
system. A large number of epidemiological studies and case reports
have substantiated the causal association between vinyl chloride
and angiosarcoma of the liver. Several studies also confirm that
exposure to vinyl chloride causes other forms of cancer, i.e.,
hepatocellular carcinoma, brain tumours, lung tumours, and malignancies
of the lymphatic and haematopoietic system. Exposure to poly (vinyl
chloride) dust was associated with an increased incidence of lung
tumours in one study; the authors suggested that trapped vinyl
chloride monomer was responsible. Melanoma occurred in excess
in one study but has not been mentioned in others. Slightly elevated
risks for gastric and gastrointestinal cancer (other than liver
cancer) were indicated in some studies, but these were not confirmed
in others.
An IARC (International Agency for Research in Cancer) Working
Group reported that there is sufficient evidence of carcinogenicity
of vinyl chloride in experimental animals. When administered by
inhalation, vinyl chloride induced pulmonary adenomas, adenocarcinomas,
liver angiosarcomas, nephroblastomas, and liver angiosarcomas
in rats of both sexes and mammary tumours and in female rats.
When administered by inhalation, vinyl chloride induced skin tumours
in male hamsters and angiosarcomas (liver, spleen, or skin), mammary
carcinomas, skin carcinomas, and stomach adenomas in female hamsters.
Newborn rats developed angiosarcomas when exposed to vinyl chloride
by inhalation. A combination of oral administration of ethanol
and inhalation of vinyl chloride resulted in more liver tumours
(including angiosarcomas) than after treatment with vinyl chloride
alone.
REPRODUCTIVE AND DEVELOPMENTAL TOXICITY1
Several epidemiological studies have been conducted to assess
potential reproductive and developmental effects in the families
of vinyl chloride workers (California Department of Health Services,
1990). Edmonds et al. (1975, 1978) conducted two case-control
studies evaluating central nervous system malformations among
offspring of vinyl chloride workers and families living near polyvinyl
chloride facilities in Indiana and West Virginia. More cases than
controls lived within three miles of the polyvinyl chloride plants
(p<0.02). Mothers living in Ohio communities with PVC production
facilities gave birth to an excess number of children with congenital
malformations as compared to the expected number based on the
state average or based on the experience in the balance of the
counties in which these cities are located. In a review of epidemiological
studies related to vinyl chloride exposure by Hemminki and Vineis
it was concluded that there was inadequate evidence linking environmental
or paternal exposures to vinyl chloride with birth defects.
Occupational Hazards
In the US, It has been shown that occupational exposures generally
occur after production, as the finished monomer is piped to storage
or transportation or during maintenance. The greatest potential
for the hazard is during polymerisation of the chemical to form
other materials, nearly all of which are PVC resins, and the vinyl
chloride escapes into the air. This has been the major emission
source and the process in which the highest occupational exposures
have been reported. The National Occupational Exposure Survey
(1981-1983) estimated that 18,386 workers, including 7,384 women,
were potentially exposed to vinyl chloride. NIOSH estimated that
27,000 workers are exposed to vinyl chloride and that as many
as 2.2 million workers are potentially exposed. According to the
Toxic Release Inventory of 1995, an estimated total of 1.01 million
pounds of vinyl chloride (99.9%of the total environmental releases)
was discharged to the air, 227 pounds (<0.03%) to the water,
and 6 pounds (<0.0006%) to the soil from manufacturing and
processing facilities in the United States in 1993
Between September 1967 and December 1973, 4 cases of angiosarcoma
of the liver were diagnosed among men employed in the polyvinyl
chloride polymerisation section of a B.F. Goodrich plant near
Louisville, Kentucky2. This section of the plant began operations
in 1938. It employs about 270 persons and produces polyvinyl chloride
as well as a variety of copolymers by polymerisation of vinyl
chloride monomer. All 4 men had worked continuously in the section
for at least 14 years prior to onset of illness; all 4 had worked
directly in various phases of the polymerisation process. Subsequently,
it has been declared that, the available data indicates the occurrence
of angiosarcoma among workers at vinyl chloride plants seems distinctly
a problem in the entire industry.
REGULATIONS THAT THE CHEMPLAST PVC PLANT VIOLATES
The following are the recent recommendations of the High Powered
Committee (HPC) on Hazardous Wastes. The Committee was empowered
by the Honourable Supreme Court of India in the writ petition
No. 657/95 (Research Foundation for Science, Technology and Natural
Resource Policy vs. Union of India and others).
The HPC Committee recommendations
(v) It is imperative that Government declare and take steps
to ensure that expansion of existing hazardous waste generating
industries and new industries of this nature follow the basic
parameters of Clean Production. New industries must be subjected
to stringent public disclosure rules regarding emissions, processes,
raw materials and hazard potential, and mitigation scenarios.
Such industries must prove that the processes used are the most
energy-efficient and environmentally safe technologies when submitting
their proposals for seeking consent to establish. They must not
be permitted to employ technologies or processes that intentionally
or unintentionally generate endocrine disrupting chemicals or
persistent organic pollutants. Nor should they be permitted to
generate products whose final disposal would poison the environment
with such chemicals or pollutants; in such cases, they must have
a cradle to grave responsibility

Excerpts from the Stockholm Convention
http://www.chem.unep.ch/pops/POPs_Inc/dipcon/meetingdocs/conf-2/en/conf-2e.pdf
The recently concluded Stockholm Convention on Persistent Organic
Pollutants discourages the increased production and release into
the environment of POP chemicals.
Preamble:
Acknowledging that precaution underlies the concerns of all the
Parties and is embedded within this Convention,
Underlining the importance of manufacturers of persistent organic
pollutants taking responsibility for reducing adverse effects
caused by their products and for providing information to users,
Governments and the public on the hazardous properties of those
chemicals,
Conscious of the need to take measures to prevent adverse effects
caused by persistent organic pollutants at all stages of their
life cycle,
Recognizing the importance of developing and using environmentally
sound alternative processes and chemicals,
Article 5
(b) Promote the application of available, feasible and practical
measures that can expeditiously achieve a realistic and meaningful
level of release reduction or source elimination;
(c) Promote the development and, where it deems appropriate, require
the use of substitute or modified materials, products and processes
to prevent the formation and release of the chemicals listed in
Annex C, taking into consideration the general guidance on prevention
and release reduction measures in Annex C and guidelines to be
adopted by decision of the Conference of the Parties;
Annex C
Part V: General guidance on best available techniques and best
environmental practices
This Part provides general guidance to Parties on preventing or
reducing releases of the chemicals listed in Part I.
A. General prevention measures relating to both best available
techniques and best environmental practices Priority should be
given to the consideration of approaches to prevent the formation
and release of the chemicals listed in Part I.
Useful measures could include: (a) The use of low-waste technology;
(b) The use of less hazardous substances; (c) The promotion of
the recovery and recycling of waste and of substances generated
and used in a process;(d) Replacement of feed materials which
are persistent organic pollutants or where there is a direct link
between the materials and releases of persistent organic pollutants
from the source; (e) Good housekeeping and preventive maintenance
programmes; (f) Improvements in waste management with the aim
of the cessation of open and other uncontrolled burning of wastes,
including the burning of landfill sites. When considering proposals
to construct new waste disposal facilities, consideration should
be given to alternatives such as activities to minimize the generation
of municipal and medical waste, including resource recovery, reuse,
recycling, waste separation and promoting products that generate
less waste. Under this approach, public health concerns should
be carefully considered; (g) Minimization of these chemicals as
contaminants in products; (h) Avoiding elemental chlorine or chemicals
generating elemental chlorine for bleaching.
B. Best available techniques
(b) General release reduction measures: When considering proposals
to construct new facilities or significantly modify existing facilities
using processes that release chemicals listed in this Annex, priority
consideration should be given to alternative processes, techniques
or practices that have similar usefulness but which avoid the
formation and release of such chemicals.
