Chimney/stack, process, fugitive, storage, and loading emission limits for petrochemical (basic and intermediates) plants
◉ ENVIRONMENT (PROTECTION) FOURTH AMENDMENT RULES, 2012 (GSR 820(E)) STYLE CHECK · NOT A REGULATORY SUBMISSION TOOL
⚠ Indicative tool only. Source: Gazette of India Extraordinary, Ministry of Environment and Forests notification G.S.R. 820(E), dated 9 November 2012, "Environment (Protection) Fourth Amendment Rules, 2012" — amending Schedule I Serial No. 38 (Petrochemical, Basic and Intermediates) and Schedule VI of the Environment (Protection) Rules, 1986. Published bilingually (Hindi then English); all figures below are transcribed from the notification's own English text, cross-checked against an independent Hindi-to-English translation of the same sections — every value matched exactly. Verify against the current, consolidated Rules (this is a single 2012 amendment; later amendments may exist) before using this for compliance purposes.

B. Chimney/Stack Emissions (Furnace/Boiler/Heater/Vaporiser)
All values corrected to 3% oxygen. Wet scrubber must operate during decoking. CO norms apply only to Phthalic Anhydride (PA), Maleic Anhydride (MA), Terephthalic Acid (PTA), and Dimethyl Terephthalate (DMT) plants — not applicable to standalone existing PA/MA plants under 30,000 MT/year with a chimney/stack ≥30m tall.
Result Not evaluated
Limit—
Process Emission — Specific Pollutant
HAP = Hazardous Air Pollutant: pollutants causing cancer or other serious health effects, or adverse environmental/ecological effects.
Result Not evaluated
Limit—
Process Emission — General Pollutant
General pollutant limits do not distinguish existing vs. new plants (single limit applies to both).
Result Not evaluated
Limit—
Schedule VI, Part D, Serial 9 — New/Expansion Plant Quantum Limits
Load/mass-based standard, applies to new or expansion petrochemical (basic and intermediates) plants specifically — a different basis than the concentration-based process emission limits above.
Result Not evaluated
Limit—
Loading Emission Control (Road Tank/Truck/Rail Tank/Wagon)
Compliance may be demonstrated by EITHER the VOC reduction percentage OR the direct emission limit — meeting either criterion is sufficient.

D. Storage of Benzene, VCM and ACN
Reference — one of three technology options shall be provided:
(i) Fixed roof tank (FRT) with vapour incineration, ≥99.9% VOC removal efficiency; or
(ii) IFRT/EFRT with double seals, emission-reducing roof fitting, fitted with fixed roof, ≥99% vapour removal efficiency; or
(iii) Internal floating roof with nitrogen blanketing between the fixed and floating roofs.
For general petrochemical/petroleum product storage (not specifically benzene/VCM/ACN), roof type by tank capacity and total vapour pressure, plus seal gap limits, are already covered in the Rim Seal Gap Survey tool's India profile (same source notification, Section C).
