1 Oil & Gas egulatory Authority LAYOUT LANS FO INSTALLATION OF LG AUTOGAS STATIONS

2 1.0 BACKGOUND & INTODUCTION: The Federal government in a meeting held on 21 st September, 2005 considered the Ministry of etroleum and Natural esources summary and approved in principle the use of LG in motor vehicles, subject to Oil and Gas egulatory Authority (OGA) providing a regulatory frame work ensuring comprehensive safety standards. In this regard, the OGA has devised a regulatory framework to ensure effective regulation, efficient monitoring and public/consumer safety. The egulatory Framework for the use of LG in the Auto sector has become a part of LG (roduction and Distribution) ules 2001 as an Appendix V by an amendment through S..O. 256 (I)/ 2007 Islamabad, the 10th March, The egulatory Framework provides a general criteria for installation of LG Autogas Stations. Now OGA has prepared a Brochure containing guidelines / layout plans in accordance with the approved egulatory Framework, showing details, including the minimum required inter distances for the equipment, storage tanks/built-up areas etc. under NFA-58. In view of the foregoing, the layout plans were developed, taking into account the following categories: Stand alone LG Autogas station LG Autogas station co-located with CNG, Gasoline & Diesel.

3 2.0 DISCUSSION ON GULATOY FAMWOK & DVLOD LAYOUTS: 2.1 egulatory Framework The egulatory Framework contains the following criteria to setup LG Autogas Stations: The LG Auto refueling/dispensing station shall only be located on roads/highways having minimum 60 feet width. The LG Auto refueling/dispensing station shall not be located in congested or residential areas nor should any of the adjacent buildings is used for accommodation or public gathering of any sort. The installation of LG refueling station shall conform to the technical standards prescribed in LG (production & distribution) ules, 2001 & NFA 58. For ensuring safety, the storage capacity at an LG auto refueling/dispensing station shall be limited to 10 metric tons (max.). In addition to the requirements of NFA-58, the minimum area for the installation of LG auto refueling / dispensing station shall be in no case is less than 10,000 sq. Feet with a minimum 80 feet frontage and depth. Only brand new equipment shall be installed at the refueling / dispensing station i.e. use of second hand equipment shall not be allowed. Conversion kit and cylinder shall only be installed at licensee approved centers and installed vehicle shall have the respective licensee s seal of compliance to NFA- 58, otherwise it will be considered illegal.

4 2.2 Layout Criteria As part of development of layouts for LG Autogas stations following criteria has been developed based on NFA-58 (Liquefied etroleum Gas Code). The minimum distance between LG vessels and property lines shall be atleast 50ft as per table The minimum distance between LG vessels and any combustible material/dry grass shall be atleast 50ft as per table The minimum distance between LG vessels and property lines shall be atleast 10ft as per section 6.24 (Alternate rovisions for Installation of ASM containers), which requires use of fail-safe product control measures and low emission transfer concepts. The minimum distance between LG vessels and buildings with fire resistant walls shall be atleast 10ft as per section The minimum distance between LG vessels and any combustible material/dry grass shall be atleast 10ft as per section and The minimum distance of LG vessels vent and any source of ignition/open flame shall be atleast 10ft and per table The minimum distance between LG vessels and any above ground petrol/diesel storage shall be atleast 20ft as per section

5 The minimum distance between LG vessels and auto dispenser shall be atleast 10ft as per table part (J). The minimum distance between LG vessels and point of transfer/decanting area shall be atleast 10ft as per table section The minimum distance between buildings with fire resistant walls and point of transfer/decanting area shall be atleast 10ft as per table part (A) and part (F). The minimum distance between source of ignition/open flame and point of transfer/decanting area shall be atleast 25ft as per section (B). The minimum distance between source of ignition/open flame and auto dispenser shall be atleast 25ft as per section (B). The minimum distance between buildings with non fire resistant walls and point of transfer/decanting area shall be atleast 25ft as per table part (B). The minimum distance between buildings with non fire resistant walls and auto dispenser shall be atleast 25ft as per table part (B). The minimum distance between auto dispenser and property line shall be atleast 25ft as per table part (D). The minimum distance between point of transfer/decanting area and property line shall be atleast 25ft as per table part (D). Metal cutting/welding shall be done atleast 35ft away from point of transfer / decanting and auto dispenser as per section (C).

6 ublic way shall be atleast 10ft away from point of transfer/decanting and auto dispenser as per table part (F). The minimum distance between points of transfer/decanting and auto dispenser shall be 10ft as per table part (F).

7 2.3 Developed Layouts The layouts developed of various options prepared are as follows: Layout of LG refueling station: Area required 20,240 sq ft Installation of ASM container as per NFA 58, sec. 6.3 with 04 dispensers (option-i). Layout of LG refueling station: Area required 17,520 sq ft Installation of ASM container as per NFA 58, sec. 6.3 with 02 dispensers (option-ii). Layout of LG refueling station: Area required 10,000 sq ft Alternate provision for installation of ASM container as per NFA 58, sec with 02 dispensers (option-iii). Layout of LG refueling station: Area required 10,000 sq ft Alternate provision for installation of ASM container as per NFA 58, sec with cng, petrol & diesel facilities (option-iv). Minimum separation distances as per NFA 58, table & table Minimum separation distances as per NFA 58, sec & table Typical hazardous area classification of LG refueling station.

15 3.0 CONCLUSION: As per NFA 58 Section 6.3 the area requirements for LG Autogas Station comes to 20,240 sq ft with 04 dispensers and 17,520 sq ft with 02 dispensers. However NFA 58 Section 6.24 provides an alternate whereby the area requirements are reduced to 10,000 sq ft with elaborate safety requirements including the following. The complete requirements are given in NFA 58, Section 6.24: Installation of internal valve with excess flow valve and positive shut-off valve. Automatic closure of all primary valves actuated by fire detection or hose pullaway. emote shutdown stations are within 15 ft and another between 25 ft and 100 ft of the transfer point.
