PROJECT REPORT
1.1 introduction
Mumbai is a rapidly expanding mega-city characterized by high levels of particulate
mater (PM) and nitrogen oxides (NOx). The annual average ambient concentration
levels of PM have exceeded national ambient air quality standards at all monitoring
sites in the city as reported under the past studies by different agonies motor vehicles
contribute significantly to the air pollution in Mumbai. Air pollution in Mumbai city is an
issue of very great concern today.
Pollution due to petroleum products used in transportation is an ever – increasing
problem for Mumbai and other metros. Emission from vehicles contribute to smog low
visibility, and greenhouse gas emissions. The impact of air pollution on the human
health and the ecosystem is increasingly been linked to the growing transport sector,
shifting to alterative fuels is the need of the day.
Alternative fuels are fuels commonly referred to as replacement for petroleum- based
fuels like diesel and gasoline, such as compressed natural gas (CNG), liquefied
petroleum gas (LPG) and biodiesel. They are considered cleaner in the sense that they
yield substantial energy supply with less impact to the environment .some of these are
agriculture – and therefore renewable.
Compressed Natural Gas is the cleanest of the fossil fuels, and thus its many
applications can serve to decrease harmful pollution levels from all sectors, particularly
when used to together with or replacing other fossil fuels in fact, according to the
environment protection agency, US(EPA). Compared to traditional vehicles, vehicles
operating on compressed natural gas have reductions in carbon monoxide emissions of
90 to 97 percent, and reductions in carbon dioxide emission of 25 percent. Nitrogen
oxide emissions can be reduced by as much as 50to 75 percent.
For this reason, the government is continually on the look out for conversion of petrol/
diesel driven vehicles to CNG fuel. Here, it is also important to cite the civil jurisdiction
of Mumbai high court in case of SMOKE AFFECTED RESIDENTS FORUM VERSUS
MUNICIPAL. CORPORATION OF GREATER MUMBAI &ORS (Writ petition no.
1762,1999. In had appointed a committee, known as lal “committee”
The court was very much concerned about the availability of CNG and the sufficiency of
the number of outlets for supply of CNG in greater Mumbai and particularly in south
Mumbai .the court devoted a lot of time on this issue with a view to see to it that
sufficient number of CNG outlets were provided. In December, 2000 the committee was
directed to identify the plots and suitable locations and finalize the terms and conditions
and approve the allotment of the plots to Mahanagar Gas Ltd. The plot under reference
in this report is one of the plots allotted to Mahanagar Gas Limited by Collector on lease
for setting up CNG Station.
CNG has already been introduced in Mumbai in a large number of taxis, autorickshaws
private cars, trucks and transport vehicles and buses. Although the recent statistics of
the total number of vehicles converted to run on CNG are not available, it is interesting
to note that Mumbai has lesser number of CNG stations compared to Delhi, but has
more vehicles running on the alternative fuel.
Benefits of using CNG as vehicular fuel are manifold sience it is low in pollutants, high
in calorific value and heat yield, economical and available in abundance.
1. Economic benefit: The cost of CNG is almost a third of cost of Petrol in terms of
calorific value resulting saving in fuel cost of Petrol in terms of calorific value
resulting in substantial saving in fuel cost, and investment on the CNG kit is paid
back in a short period.
2. Environment friendly: The use of CNG a fuel reduces vehicular exhaust
emissions significantly. Carbon Monoxide emissions are reduced by 70 to 90%
and Hydrocarbon emissions by 40 to 69% as compared to vehicles that uses the
conventional fuel-Petrol. Carbon Dioxide emissions, a causes for global warming,
are also reduced significantly by 10%
3. Income Tax Depreciation: Corporate Organizations, films, etc. can claim 100%
depreciation on a CNG Conversion Kit as this is a pollution controlling
equipment.
4. Flexibility and ease of use: The basic engine characteristics of a vehicle are
retained while converting it to run on CNG. The vehicle therefore is capable of
running either of Petrol on Petrol or CNG at the flick of a switch on its dashboard.
5. Toxicity: CNG is longer and nontoxic to skin and lungs compared to Petroleum
and diesel which are moderately toxic and heavier.
1.2 About Company
Mahanagar Gas Limited (MGL), a pioneering initiative to bring clean, safe
efficient and affordable Piped Natural Gas, direct to over 6,00,000 homes in
Mumbai. Presently MGL has connected more than 4.29 lakh households in and
around Mumbai. The MGL project, which started in 1995 from Chembur, has
covered major parts of Mumbai through its distribution network i.e. from South
Mumbai to Mira Road and from Sion to Mulund. MGL has already started work in
South Mumbai areas like Prabhadevi, Worli, Colaba etc. From cooking stoves to
geysers and air-conditioners, this versatile gas has today become the preferred
choice for the residents of Mumbai.
Fulfilling the promise of a clean Mumbai, MGL’s Compressed Natural Gas (CNG)
powers over 60,099 taxis/cars, more than 1.33 lakh autorikshwas, 1948 BEST
buses, 66 TNT Buses, 340 Private Buses and 47 Mini Buses across the city
through it’s network of 139 CNG stations having 698 dispensing points, thus
contributing to more than 900 tonnes reduction of pollutants every day.
MGL has ambitious future plans for CNG & PNG expansion in Mumbai, Thane &
Navi Mumbai. The MGL has laid over253.41 kms of steel pipeline and over
2615.66kms of polyethylene pipeline. Further, the plan includes setting up of
more number of CNG outlets as well as enhancing CNG compression capacity
and dispensing points to provide CNG to the vehicles with minimum possible dry
run and waiting.
The proposal to establish CNG distribution station at this location was first
mooted by MGL to MMRDA way back in 2001 and according steps were initiated
to obtain the necessary regulatory permission for the same by MGL.
1.3 Site Overview
In order to meet the vehicular CNG demands of Navi Mumbai, MGL proposes to
set up a CNG station at the Mankhurd plot bearing CTS No- 1(Pt).
The proposed CNG Station project is geographically located at intersection of
latitude 19003’26”N and longitude 72055’53”E. The site for CNG station is in the
residential zone, as per the approved DP plan of the area. The CRZ notification
permits the storage of CNG in CRZ area expect the CRZ(III) and the proposed
location of the CNG station is not in CRZ (I) since the area is classified as
CRZ(III) in the approved CZMP of the area. Similarly the existing DC rules
(Schedule 1, Para II, Section 55, and table 23, Serial No. XI (36B) also permit the
setting up of CNG station in the area. The proposed site is at to Mankhurd plot
bearing CTS No- 1(Pt) adjacent to Ghatkopar Mankhurd link road. The Google
map of the location and layout plan of the site are enclosed as annexure 1 and 2
respectively.
The proposed project is planned in an existing non agriculture vacant land. The
project area is well connected to the existing road network. The closest road is
Ghatkopar Mankhurd link road is adjacent to the project site. The nearest railway
station is Mankhurd which is 1km (approx.) from the project site. The project is a
refilling station the connectivity with road network is an important consideration
and is already taken care of.

providing availability of CNG to the vehicles in that area. It will benefit the vehicle s from
south Mumbai to obtain their fuel requirement s from nearby locality instead of traveling
to CNG stations distantly located CNG stations. This will save on time, fuel & money of
the vehicle owners. MGL shall be able to fulfill its obligations of cleaned fuel supply to
south Mumbai residents & in turn achieve the goals of air pollution prevention.
-
From transport sector, as enunciated in the orders given by the Hon’ble Mumbai
High Court on the use of CNG for the vehicles.
1.6 Outcomes:
-
It is concluded that development of the CNG station in the CRZ II area is possible in
view of the regulatory provisions in the CRZ notification that permit such
development. The adequate safety measures will be taken in the project. The
proposed project shall immensely benefit the residents of South Mumbai area and
shall also help in reducing the air pollution resulting in improvement of the existing
air quality in the area.
