Originally enacted as the 'Environmental Protection (Diesel and Petrol) Regulations 1999', it originally covered both diesel and petrol standards. The 2012 amendments removed all diesel-related provisions (deleting Part 2 and regulations 4-6, 7-8, 12-13, 15, and 22), renamed the regulations to focus solely on petrol, and introduced new petrol-specific provisions (regulations 3B, 10, 11, 16-19).

The rules limit this to 0.10% by volume statewide.\n- **Reid Vapour Pressure (RVP)** — a measure of how easily petrol evaporates. High RVP increases smog (ground-level ozone) in hot weather. The rules set strict limits on RVP for petrol sold in the Perth metropolitan area during summer months (15 October to 15 April).\n\n**Who it affects:**\n\n- **Fuel suppliers** — companies that import or manufacture fuel and sell it to others or use it themselves\n- **Fuel distributors** — businesses that buy fuel from suppliers and on-sell it (like petrol stations or bulk distributors)\n- **Motorists in Perth** — indirectly, through cleaner-burning fuel during summer\n\n**Key requirements:**\n\n- **Statewide MTBE cap**: No petrol sold in WA can contain more than 0.10% MTBE\n- **Perth summer RVP limits**: Stricter evaporation limits apply in the Perth area during summer, with different rules for regular petrol versus ethanol-blended petrol (E10)\n- **Record keeping**: Fuel suppliers must test each batch of petrol and keep records for 24 months\n- **Warranties**: Suppliers must give written guarantees to distributors that fuel meets these standards\n\n**Exemptions:**\n\n- Racing fuel for approved motorsport events\n- Diesel, LPG, natural gas, and pure alcohol fuels\n- Emergency situations (if a state of emergency is declared under fuel shortage laws)\n\n**Why it matters:**\n\nThese rules reduce air pollution in Perth during hot months when smog formation is worst, and protect groundwater from MTBE contamination. The regulations were significantly updated in 2012 to introduce stricter summer standards and remove earlier diesel-related provisions (the regulations originally covered both diesel and petrol)."},"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
