1.0 INTRODUCTION

These guidelines aim to address environmental issues associated with the design, operation, maintenance and management of stormwater/wastewater infrastructure for service stations and other sites that dispense fuel to road vehicles, forklifts and other equipment. Spillage from such activities may contain suspended solids, petroleum hydrocarbons and heavy metals with the potential to contaminate soil and/or ground and surface waters both onsite and offsite.

Service stations undergoing development assessment (either as a new service station or for substantial refurbishment or material change of use) should comply with these guidelines.

2.0 LEGISLATION

Current legislation relating to stormwater management from service stations includes:

Environment Protection Act 1994 where “a person must not carry out an activity that causes, or is likely to cause, environmental harm, unless the person takes all reasonable and practicable measures to prevent or minimise the harm”. Eighty-five Environmentally Relevant Activities (ERA’s) are identified and defined for direct regulation under this legislation. This Act devolves powers to local authorities to administer 23 of these ERA’s including ERA 11 – “Crude oil or petroleum product storing” under which service stations fall. Under this Act, pollution of both groundwater and the contamination of underlying soil is an offence.

• Environment Protection (Water) Policy 1997 – Sections 31 and 32 where a person must not deposit or release oil, rubbish, a degreasing agent

and motor vehicle parts (among other pollutants) into a roadside gutter, stormwater drain or a waterway; or in a place where it could reasonable be expected to move or be moved into any of these.

• Water Act 2000 – prohibited substances to a sewerage system include:

A flammable or explosive solid, liquid or gaseous substance (including petrol). Oil and grease. Gross solids (greater than 13mm in diameter) Floodwater, rainwater and stormwater, and roof water, seepage water, subsoil water and surface water.

• City Plan – Service Station Code (2000) is to facilitate the appropriate siting of service stations with regard to surrounding amenity and

environmental values.


3.0 DESIGN AND INFRASTRUCTURE

This section outlines the design and infrastructure required to manage water quality on the forecourt areas of service stations and sites with fuel dispensing.

3.1 New Sites - Fuel Dispensing Areas - Under Canopy

Areas in close proximity to fuel dispensing equipment carry a high environmental risk associated with intensive fuelling activity and the potential for minor spills to accumulate. Likely pollutants within fuel dispensing areas (FDA) can include fine and coarse sediment, surfactants/detergents, oils, grease, petrol and diesel fuels, heavy metals plus other motor vehicle liquid consumables such as glycols from radiator antifreeze, hydraulic fluids and general litter.

Performance Criteria Acceptable Solutions Notes/Comments P3.1.1 – Approved Surface Materials All ground surfaces within Fuel Dispensing Areas must be made of impervious material

A3.1.1 – Approved Surface Materials All ground surfaces within the FDA shall be constructed of concrete with all gaps and/or cracks filled so that the impervious barrier and integrity is maintained.

Asphalt is not considered a suitable equivalent as it can react with hydrocarbons.

P3.1.2 – Demarcation of FDA All Fuel Dispensing Areas must be clearly demarcated from other areas such as air/water supply areas, uncovered forecourt, access roads. The FDA shall be designed and operated so that no vehicle can be refuelled outside this demarcated area.

A3.1.2 – Delineation of FDA The FDA shall be delineated by painted line-work on the ground. Other methods of delineating the FDA may be used eg. roll-over bunds, different colour concretes, etc.

P.1.3 - Fate Of Flow Information Staff and persons using the facility shall be informed of fate of flow of drainage from the area.

A3.1.3 - Fate of Flow Signage Signs indicating fate of flow such as “flows to containment vessel” shall be provided in locations around the under-canopy area.

Signage may be stencilled to the ground surface.


Performance Criteria Acceptable Solutions Notes/Comments P3.1.4 – Spillage containment of FDA Contaminants in excess of those stipulated in BCC’s Guideline on Identifying and Applying Water Quality Objectives must not be released into stormwater infrastructure, roadside gutters, or other waters outside of property. Due to the increased risk of contamination in this area, any containment and treatment solution shall incorporate appropriate “fail safe” features in its design. Prior design approval shall be obtained from Water Resources Branch.

A3.1.4 - Underground containment vessel - Blind sump The area shall be graded to a suitable underground containment vessel (i.e. sump/tank) compatible with petroleum products and other likely chemicals. The tank shall have no connections to stormwater or sewer. The containment vessel shall be constructed of precast concrete with a minimum certified design life of 50 years and be designed in accordance with AS 3600 - “Concrete Structures”. All internal concrete surfaces that may be exposed to contact with petroleum hydrocarbons shall be coated with an epoxy resin, to a minimum dry film thickness of 200 microns, applied in accordance with the supplier’s recommendations. Joints shall be made with epoxy or rubber ring seals. Epoxy joints shall be Megapoxy P1 or approved equivalent and used in accordance with supplier’s recommendations. For joints using a rubber ring seal, the rubber type shall be NBR (nitrile) complying with AS 1646.3 (Elastomeric seals for waterworks purposes – Material requirements for pipe joints seals used in water and wastewater applications with the exception of natural rubber and polyisoprene compounds). The ring shall be water tight to 90kPa internal pressure and comply with the general requirements of AS 1646.1 (Elastomeric seals for waterworks purposes – General requirements).


Performance Criteria Acceptable Solutions Notes/Comments A3.1.4.1 - Capacity The underground containment vessel shall maintain adequate capacity to contain both a volume equivalent to at least the volume of the largest tanker compartment likely to be delivering fuel to the site plus a nominal allowance for windblown rain. Windblown rain allowance in m3 (Vr) should be calculated using the following equation: or PV ××= 3005.0 , where Po is the total length of the open perimeter of the canopy in metres.

Where the only fuel used on-site is diesel or another Combustible Liquid, the total containment storage may be considered to be inclusive of pipework and surface storage (ie. within the bunded fuel dispensing area).

P3.1.5 – Canopy requirements for FDAs All Fuel Dispensing Areas must be covered by a roof or canopy to minimise stormwater entering the FDA.

A3.1.5 - Canopy Overhang The roof or canopy shall overhang by a horizontal distance of ¼ of the roof height out from the vertical above the boundary of the demarcated FDA.

Canopy design is important to minimise the amount of wind blown stormwater entering the sump.

P3.1.6 – Canopy Stormwater Stormwater from the canopy roof shall be conveyed to stormwater drainage separate from drainage for the FDA.

A3.1.6 - Canopy Stormwater - Disposal Options Preference is for stormwater from roofed areas to be collected in tanks for non-potable use (eg. toilet flushing or garden watering). Alternatively, it may be diverted directly to on-site stormwater infrastructure.

P3.1.7 – Bulk Fuel Transfers All spills and leaks from bulk fuel transfer activities (i.e. fuel tanker trucks delivering and filling fuel storages at the site) must be contained on-site.

A3.1.7 – Bulk Fuel Transfer – Under-Canopy Option Bulk fuel transfers may be carried out under the canopy area within a defined Tanker Delivery Standing Area graded and drained to the underground containment vessel.

Alternatively, Tanker Delivery Standing Areas outside of the canopy will require modifications that automatically divert run-off to the underground containment vessel during bulk fuel transfers. See section P3.2.4. At all other times, drainage shall be directed to on-site stormwater infrastructure for uncovered areas.


3.2 New Sites – Uncovered Areas (Outside of Canopy)

Uncovered areas include access roads and the forecourt between Fuel Dispensing Areas and the site boundary. The most significant stormwater pollutants associated with these areas include hydrocarbons, sediment, heavy metals and litter. Fuel Dispensing Areas are not permitted on uncovered forecourts.

Performance Criteria Acceptable Solutions Notes/Comments P3.2.1 – Ground Surface Material All ground surfaces in uncoverd areaswithin the site boundary liable to contamination from vehicular activities must be constructed of impervious material as per condition P1.1.2

A3.2.1 - Approved Surface Materials All ground surfaces not under canopy shall be constructed of concrete or equivalent with all gaps and/or cracks filled so that the impervious barrier and integrity is maintained.

Asphalt is considered a suitable equivalent provided there is strictly no refuelling of any kind in this area.

P3.2.2 – Separation of Drainage All uncovered, impervious areas of the site must direct any stormwater or other surface run-off away from drainage systems for Fuel Dispensing Areas.

A3.2.2 - Drainage Separation Options Drainage separation options may include grading, bunding, kerbing and/or channelling.

Separation is required to assist in maintaining the spill capacity of the containment vessel.

P3.2.3 – Stormwater Treatment All discharge to stormwater must comply with the best practice discharge standards as outlined in the current version of Brisbane City Council’s Guideline on Identifying and Applying Water Quality Objectives in Brisbane City - 2000. The stormwater treatment system must be designed to meet BCC’s Water Quality Objectives as set out in the Guideline for Identifying and Applying Water Quality Objectives in Brisbane.

A3.2.3 - Approved Options Any Stormwater Quality Improvement Device (SQID) or treatment train shall be in compliance with section 3.2.1.


Performance Criteria Acceptable Solutions Notes/Comments P3.2.4 – Bulk Fuel Transfer – Uncovered Areas Where bulk fuel transfers and tanker delivery standing areas are outside the under-canopy area, all risks shall be identified and measures shall be taken to prevent spills from flowing offsite.

A3.2.4 - Bulk fuel transfer – automatic diversion valves Bulk fuel transfers shall be carried out in a defined Tanker Delivery Standing Area. This area shall normally be drained to the uncovered area stormwater treatment system. However, during fuel delivery operations, automatic diversion valves shall be used to divert such drainage to the under-canopy containment vessel. The Tanker Delivery Standing Area in uncovered locations shall be sized so that the drainage area has a radius of at least 3 meters and a storage volume equivalent to that of the largest tanker storage compartment that is expected on site at any given time.

P3.2.5 - Fate Of Flow Information Staff and persons using the facility shall be informed of fate of flow of drainage from the area.

A3.2.5 - Fate of Flow Signage Signs indicating fate of flow such as “flows to creek” shall be provided in locations around the uncovered area.



3.2.1 Stormwater Quality Improvement Devices

Source controls (e.g. bins and signage, and regular pavement cleaning) should make up part of stormwater quality management procedures on Service Stations and sites with fuel dispensing. Details of required site management practices are outlined in Section 4.0.

Stormwater Quality Improvement Devices (SQIDs) are required to meet Brisbane City Council’s Water Quality Objectives in most cases a treatment train (a number of SQID’s in a row) is required to ensure the stormwater meets this target. Some commercially available devices may be capable of meeting these standards with an individual device, however provision of substantial research is required to support any design submission. The treatment train must include but not be limited the following devices:

• Steel bars or a trash gate with 20-25mm spacing.

• Gross Pollutant Traps (GPTs)/filtration devices (e.g. sand filters) capable of removing both litter (diameter greater than 5mm) and 70% of fine sediments (>125µm) that typically dominate the total suspended solids load and transport a range of sorbed contaminants such as heavy metals, hydrocarbon and petroleum products. These must be installed at the upstream end of the treatment train to protect downstream devices and have sufficient capacity to maintain Water Quality Objectives during a storm up to the 2 year ARI – 6 minute design rainfall intensity. Drainage must be designed with sufficient capacity to prevent surcharging and ‘backing-up’ such that there is no standing water anywhere on the site during a storm up to the 10 year ARI – 6 minute design rainfall intensity.

• An appropriately sized wastewater treatment device capable of removing droplets larger than 60µm (i.e. corresponding to outlet discharge of approximately 15mg/L) and to a point where there is no visible sheen or odour on stormwater1. These must be able to meet these standards during a storm up to the 2 year ARI – 6 minute design rainfall event without surcharging and ‘backing-up’ the drainage system. Oil levels within the separator tank must be checked on a monthly basis2. Where oil is identified, the separator must be emptied and waste product/water disposed of by a licensed waste transport contractor at an EPA approved liquid waste treatment facility. Flow cut-off valves must be installed at the outlet from the separator for use in an emergency or during cleaning operations. Independent performance certification shall be submitted for approval by Water Resources Branch prior to installation.

• Where space and site layout are suitable, water that has been treated may be discharged to a grassed swale, filter strip or infiltration system within the property boundary, prior to discharging into the Council stormwater drainage system.

1 Capability is conditioned to demonstrated risk.

2 New sites and existing sites undergoing a significant fore court upgrade must install automatic oil level alarms and closure devices. The alarm should be set to provide warning when the level of oil reaches 90% of the oil storage volume under static liquid level conditions. These devices must be intrinsically safe.


All treatment measures must be designed in accordance with the requirements of the Water Sensitive Urban Design Engineering Guidelines: Stormwater (Brisbane City Council, 2005), particularly with respect to:

• Hydraulic and hydrologic aspects;

• Design, construction and operation; and,

• Maintenance.

More information on water quality management is contained in the Subdivision and Development Guidelines (Brisbane City Council, 2000b).


3.3 Existing Sites – Fuel Dispensing Areas – Under Canopy.

Dispensing areas for many older, existing sites will not have been initially constructed with adequate drainage and infrastructure to contain spills and other contaminants on-site. It remains, however, the responsibility of the operator to prevent contaminants from flowing off-site and causing environmental harm. While there is no immediate requirement for existing sites to amend surface gradients and retrofit drainage infrastructure, all reasonable precautions must be made to prevent contaminated run-off from leaving the site. To assist operators in meeting this obligation, the following minimum interim measures are to be implemented together with the appropriate management practices as outlined in Section 4.0. These interim measures must not be considered as alternatives to implementing condition levels 3.1.1 – 3.1.7, altogether or individually.

It should be noted that compliance with the requirements for new sites must be completed at the next significant forecourt/equipment upgrade.

Performance Criteria Acceptable Solutions Notes/Comments P3.3.1 – Approved Surface Materials for FDAs All ground surfaces within FDAs must be made of impervious material.

A3.3.1 – Approved Surface Materials All ground surfaces within the FDA shall be constructed of concrete with all gaps and/or cracks filled so that the impervious barrier and integrity is maintained.

Asphalt is not considered a suitable equivalent as it can react with hydrocarbons.

P3.3.2 – Demarcation of FDA All FDAs must be clearly demarcated from other areas such as air/water supply areas, uncovered forecourt, access roads. The FDA shall be designed and operated so that no vehicle can be refuelled outside this demarcated area.

A3.3.2 – Demarcation of FDA The FDA shall be delineated by a painted line on the ground. Other methods of delineating the FDA may be used eg. roll-over bunds, different colour concretes, etc.

Demarcated areas may be defined by canopy areas and the length of dispensing hoses.

P3.3.3 – Fate Of Flow Information Staff and persons using the facility shall be informed of fate of flow of drainage from the area.

A3.3.3 – Fate of Flow Signage Signs indicating fate of flow such as “flows to creek” shall be provided in locations around the forecourt area.



4.0 MANAGEMENT PRACTICES

The following management requirements shall be implemented on all existing and new service stations and sites with fuel dispensing where applicable. These requirements ensure risks are identified, prioritised and adequately managed on a day-to-day basis. Operators must comply with relevant environmental licensing requirements and the provisions of any relevant Australian Standards. Council’s Business Environmental Guidelines for Petroleum Product Storage must also be used to develop suitable management procedures. All employees are responsible for implementation of management practices and proprietors are responsible for ensuring all employees are aware of management practices obligations and receive appropriate training.

5.0 GLOSSARY

The forecourt of a service station is any paved area of the site which vehicles traverse and/or which may accumulate pollutants by way of the activities that occur on that area. The covered forecourt is comprised of those areas that are covered by a canopy or roof (usually in proximity to fuel dispensers). Material Change Of Use of premises means: (a) the start of a new use of the premises; or (b) the re-establishment on the premises of a use that has been abandoned; or (c) a material change in the intensity or scale of the use of the premises The uncovered forecourt is any forecourt area associated with the dispensing of fuels not covered by a roof or canopy. Significant Forecourt Upgrade/ Substantial Refurbishment: Generally the entire forecourt is replaced (as opposed to repaired that would only involve the replacement of a section of forecourt) and where it afford a practicable opportunity to reconfigure surface drainage to confine spills and leeks on site. Stormwater is considered to be water that drains off roof areas and uncovered pavement areas. Tanker Delivery Standing Area (TDSA): Designated area/s where a fuel delivery vehicle normally stands to unload fuel into bulk storage tanks. USS Management System: A system developed by the USS owner/operator which clearly defines requirements, procedures and responsibilities for management of the USS. To be documented and a copy kept on site. Wastewater is considered to be any liquid which drains from covered pavement areas, work areas, petroleum dispensing areas or other contaminated areas (including any rain water which may intrude into these areas).
