Protection for CNG

The explosion at the CNG station in Super Market F-6, set me thinking on whether there are any laws or regulations to regulate the safety and health issues related to the setting up of CNG stations in the city of Islamabad. According to a statement by Pakistan Environment Protection Agency, the compressed natural gas filling stations have been set up in the Islamabad city in violation of the environmental laws as none of these CNG stations have obtained clearance certificate from PEPA. Under section 12 of the Pakistan Environmental Protection Act 1997, it is mandatory to seek approval from environmental protection agency/department for establishing projects having adverse environmental effects. The Agency has repeatedly asked the Oil Companies Advisory Committee to advise its member organizations to follow the legal requirements in future.and also asked the committee to explain clearance certificates were not obtained by its member companies to establish CNG facilities at their respective outlets.

Petrol Stations typically include provisions for dispensing of motor gasoline and diesel and more recently compressed natural gas (CNG). There are also stations set up solely for the dispensing of CNG. The gasoline and
diesel, supplied through bowzers, are generally stored in underground tanks and pumped out into the vehicles via the dispenser that also meters the flow. The natural gas is generally piped to the station from the local utility. At the
station a compressor compresses and stores the gas in banks of cylinders from where it is fed to the dispenser for filling the CNG tanks in vehicles.

According to PEPA, the following are some of the rules to be followed when setting up or granting clearance sertificate to CNG filling stations:

Petrol stations should not be located in the close proximity of hospitals, schools, mosques, and parks.

Taking delivery of Fuel
 Prepare proper pad for bowzer parking while unloading.
 Ensure the pipe and couplings for the fuel transfer are secured tight and drip pans are put in all likely places where leakage can occur to avoid loss to ground.
 Schedule deliveries at times of light traffic load to avoid congestion.

Storage of fuel
 Underground fuel storage tanks are onstructed to modern specifications with secondary containment, impervious linings and leakage monitoring wells in place
 Piping from tanks to the dispensers to be above ground to the extent possible. All buried piping routes to be clearly marked on the ground and on drawings available at the station.
 Effective monitoring program for tank integrity checking and leak detection to be in place

Operation of the fuel dispensers
 While refueling, drip pans should be used to avoid spillage
 Impervious surfaces to be well maintained at all places likely to receive spills
 Station should have enough spacing between dispensers for vehicles to queue up without effecting flow of traffic

Makes you wonder doesn’t it as to how many of these regulations are actually followed especially when you think about the fact that these are just the environment aspects of the legislation governing set up of such stations.

    I think this calls for a wakeup call. If someone wants to blow up themselves in their gas stations, by all means. Why should innocent customers like us be the victims :$

    @ Talha: Buhahahaa!! Me is back! better than before! 2 posts in a day! :-D besides should always leave the audience wishing for more :)

    @ 1967: Let’s hope the wkeup call works for the concerned now before innocent people suffer serious loss and pain. The CDA is supposed to ensure that all CNG stations have the NOC and the clearance certificate from PEPA before commencing operations… Unfortuately, they are least bothered as long as their pockets are full.

    @ Asma: Captain, my captain!:) The major oil companies that own the majority of the stations are supposed to ensure that these regulations are met! bechare ghareeb kaam karne wale ki baari toh baad mein aayegi! and in the second place, the CDA has a directorate concerned specifically with regulation of Petrol/CNG pumps, and are respobsible for verifying that all the companies applying to set up these stations have the requisite paperwork from PEPA
