Bombay High Court Quashes MPCB Circular Imposing Territorial Limits on Hazardous Waste Operations

Introduction

In a significant ruling for environmental regulation and business freedoms, the Bombay High Court has declared that the Maharashtra Pollution Control Board (MPCB) lacks the authority to impose territorial restrictions on an authorized hazardous waste pre-processing facility through executive circulars. The division bench, comprising Chief Justice Shree Chandrashekhar and Justice Gautam A. Ankhad, quashed an amended circular dated February 15, 2024, and a related clause in the Consent to Operate (CTO) issued to petitioner Green Gene Enviro Protection and Infrastructure Limited. This decision underscores that such actions violate Article 19(1)(g) of the Constitution, which guarantees the right to practice any profession or carry on any occupation, trade, or business. The case, Green Gene Enviro Protection and Infrastructure Limited v. State of Maharashtra & Ors. (Writ Petition No. 2885 of 2025), arose from the MPCB's attempt to enforce a tripartite agreement favoring another facility, effectively curtailing the petitioner's statewide operations. The ruling reinforces the primacy of statutory frameworks over administrative overreach in hazardous waste management.

Case Background

Green Gene Enviro Protection and Infrastructure Limited, a company with over 15 years in the hazardous waste pre-processing sector, operates facilities across India, serving more than 10,000 industries. In Maharashtra, it established a Common Hazardous Waste Treatment, Storage, and Disposal Facility (CHWTSDF) in Sangli after receiving land allotment from the Maharashtra Industrial Development Corporation (MIDC) on March 10, 2017. The MPCB granted Consent to Establish (CTE) for this facility, which was later revalidated with amendments on December 26, 2022. Subsequently, a CTO was issued on June 26, 2023, valid until May 31, 2028, authorizing the company to pre-process up to 275,000 metric tonnes (MT) of hazardous waste annually. This included manufacturing alternate fuels from organic and inorganic hazardous wastes and non-hazardous wastes.

The facility began operations, sourcing waste from industries across Maharashtra, including key zones like Ranjangaon and Butibori. However, on February 15, 2024, the MPCB issued an amended circular that mandated industries in the operational areas of CHWTSDFs at Ranjangaon and Butibori—managed by entities linked to respondent Shaktikumar M. Sancheti Limited (SMS)—to route their hazardous waste exclusively through those facilities for pre-processing and co-processing. This stemmed from a 2004 tripartite agreement between MIDC, MPCB, and SMS, which allocated specific areas to SMS's special purpose vehicles, Maharashtra Enviro Power Limited (MEPL) for Ranjangaon and Vidarbha Enviro Power Limited (VEPL) for Butibori.

The amendment effectively reserved large industrial zones for SMS, leaving Green Gene with access to only a fraction—about 10%—of Maharashtra's geographical area, primarily districts like Palghar, Thane, Mumbai, Raigad, Ratnagiri, and Sindhudurg. On June 12, 2025, the MPCB incorporated Clause 19 into Green Gene's CTO, mirroring the circular's restrictions and prohibiting waste collection from the reserved zones until the tripartite agreement's term expires (20 years from operations or site closure).

Green Gene challenged this via writ petition, arguing it destroyed business viability, as over half its turnover derived from Ranjangaon and Butibori sources. The company had invested Rs. 77.21 crores based on prior permissions allowing statewide operations. Meanwhile, allegations of violations by SMS facilities surfaced in National Green Tribunal proceedings (Original Application No. 14 of 2025). The timeline highlights a shift: initial consents enabled broad operations, but the 2024 circular and 2025 CTO amendment sought to retroactively enforce the 2004 agreement, ignoring the 2016 Hazardous and Other Wastes (Management and Transboundary Movement) Rules (HWM Rules).

The core legal questions were: Does the MPCB have jurisdiction under the HWM Rules to impose territorial limits via circulars? Does such restriction infringe constitutional rights? And can a pre-existing tripartite agreement override statutory permissions granted to third parties like Green Gene?

Arguments Presented

The petitioner, represented by Senior Advocate Zal Andhyarujina, contended that the amended circular and Clause 19 violated principles of natural justice, as no hearing was afforded before curtailing accrued rights. Citing Director General of Foreign Trade v. M/s Kanak Exports (2016) 2 SCC 226, they argued that statutory clearances created legitimate expectations under the doctrine of promissory estoppel, entitling Green Gene to operate statewide. The restrictions were unreasonable under Article 19(1)(g), reducing viable areas to negligible portions and fostering a monopoly for SMS. They emphasized that the HWM Rules, notified under the Environment (Protection) Act, 1986, envision transboundary waste movement without geographical curbs on authorized facilities. The tripartite agreement, predating the 2016 Rules, could not bind third parties or subvert statutory frameworks. Green Gene highlighted its Rs. 77.21 crore investment and reliance on prior CTE/CTO, urging quashing on grounds of arbitrariness and discrimination.

The respondents—MPCB (Respondent No. 2, represented by Senior Advocate Jayprakash Sen), State of Maharashtra (Respondent No. 1), and others—defended the actions as fulfilling obligations under the 2004 tripartite agreement and earlier memoranda (e.g., 2001 MoU with MIDC, MOEF, and Trans Thane Creek Waste Management). Clause 8 of the agreement obligated MPCB to route waste from allocated areas to SMS facilities and barred consents for competing TSDFs in those catchments. The amended circular, issued under Rule 16 of the HWM Rules (monitoring common facilities) and general superintendence powers, ensured compliance with this binding contract, valid for 20 years from operations (commencing 2008). MPCB argued Green Gene could still source from 13 other districts, negating claims of total curtailment. They dismissed maintainability, suggesting appeals under Sections 28 of the Water and Air Acts, and noted similar restrictions in other CTOs (e.g., to Synergy Techno Ventures LLP in November 2024).

SMS (Respondent No. 4, represented by Senior Advocate M.G. Bhangde) reinforced exclusivity under Clause 11 of the tripartite agreement, prohibiting MPCB from permitting rivals in allocated zones. They claimed the circular merely clarified routing to prevent circumvention of contractual duties.

In rejoinder, the petitioner invoked Whirlpool Corporation v. Registrar of Trade Marks (1998) 8 SCC 1 and Harbanslal Sahnia v. Indian Oil Corporation (2003) 2 SCC 107 to affirm writ maintainability against patently illegal actions, stressing the circular's non-clarificatory nature—it subverted Rules rather than implementing them.

Legal Analysis

The court's reasoning centered on the HWM Rules' scheme, which prioritizes environmentally sound management without empowering State Pollution Control Boards (SPCBs) like MPCB to dictate operational territories. Rule 4 outlines occupiers' responsibilities—prevention, minimization, reuse, recycling, recovery (including co-processing), and safe disposal—requiring wastes to go to authorized users or facilities, but without geographic limits. Rule 5 assigns State Governments roles in allocating industrial space for recycling and pre-processing, while Rule 6 mandates authorizations tied to CTE and CTO, without area restrictions. Chapter III facilitates transboundary movements, underscoring fluidity.

The bench held the amended circular impermissibly enforced the tripartite agreement against third parties, creating a monopoly and overriding statutory rights. Citing M/s Motilal Padampat Sugar Mills Co. Ltd. v. State of Uttar Pradesh (1979) 2 SCC 409, it applied promissory estoppel: Green Gene altered its position (massive investment) relying on MPCB's assurances via CTE/CTO, making retraction inequitable. Delhi Cloth and General Mills Ltd. v. Union of India (1988) 1 SCC 86 clarified no proof of detriment is needed if reliance is established. The doctrine binds government instrumentalities to prevent injustice, absent legal prohibition—which was absent here, as Rules permit statewide operations.

Precedents like Allegheny College v. National Chautauqua County Bank (1927) influenced the estoppel discussion, noting its evolution against governments for fairness. The court distinguished: while Rule 16 allows SPCBs to monitor facilities per Central Pollution Control Board (CPCB) guidelines, it does not authorize territorial curbs. The 2022 circular merely echoed Rules, but the 2024 amendment subverted them, lacking statutory sanctity. Invoking Murugesam Pillai v. Manickavasaka Desika Gnana Sambandha Pandara Sannadhi (1917 SCC OnLine PC 1), the bench criticized MPCB's incomplete disclosures (e.g., 12 other facilities' statuses).

Crucially, the field of guidelines is occupied by the Central Government under the Environment Act; SPCBs cannot issue contrary circulars impeding trade. This violated Article 19(1)(g), as restrictions were arbitrary, discriminatory, and unrelated to environmental goals. The tripartite agreement bound only signatories, not Green Gene, and post-2016 Rules, it could not justify overriding authorizations.

The analysis clarified distinctions: executive circulars clarify/implement statutes but cannot circumvent them; monitoring (Rule 16) ensures compliance, not exclusivity; and constitutional rights prevail over contracts harming third parties.

Key Observations

The judgment featured several pivotal excerpts emphasizing the court's stance:

• On the circular's invalidity: “The Amended Circular dated 15th February 2024 has no sanctity in law and cannot be enforced qua the petitioner-company to curtail its rights to receive the hazardous wastes and other wastes for pre-processing/co-processing from the industries located in the State of Maharashtra. The impugned Circular is illegal, arbitrary and discriminatory and infringes the right of the petitioner-company under Article 19(1)(g) of the Constitution of India.”

• On statutory bounds: “The MPCB is to act within the four corners of the Rules. The field for issuing any Circular, guidelines, etc., is occupied by the Central Government and the MPCB has no jurisdiction to issue a Circular contrary to the provisions under the Rules and to impede the free movement of trade and business.”

• On promissory estoppel's application: Drawing from Motilal Padampat , the court noted promises creating legal relations, acted upon, bind parties to prevent inequity, especially against government actions.

• Regarding the agreement's limits: “The MPCB cannot take refuge to the Tripartite Agreement to issue the Amended Circular incorporating a clause which has no relation whatsoever with the duty and obligation under the Rules.”

• On monitoring vs. restriction: Rule 16 empowers oversight but “there is no indication under the HWM Rules that the State Pollution Control Board can restrict the area of operation of an occupier of captive facility or operator of a common facility.”

These observations highlight the balance between environmental regulation and constitutional protections.

Court's Decision

The Bombay High Court allowed the writ petition, quashing the amended circular dated February 15, 2024, and Clause 19 of the CTO dated June 12, 2025, as “illegal, without jurisdiction and violative of Article 19(1)(g).” The operative order stated: “For the aforesaid reasons, the Circular dated 15th February 2024 and Clause 19 in the CTO issued to the petitioner-company on 12th June 2025 are quashed.”

Practically, this restores Green Gene's statewide operations, enabling waste sourcing from all Maharashtra industries, including Ranjangaon and Butibori, without territorial barriers. It invalidates similar restrictions in other CTOs, potentially benefiting 12+ facilities undisclosed by MPCB. Broader implications include curbing SPCB overreach: future circulars must align with HWM Rules and CPCB guidelines, preventing contractual favoritism from trumping statutes. This bolsters business certainty in green sectors, as investments rely on uncurtailed permissions.

For legal practice, it signals vigilant scrutiny of administrative actions under Article 19, promoting promissory estoppel claims against regulatory flip-flops. Environmentally, it encourages competitive, efficient waste management without monopolies, aligning with sustainable goals under the Environment Act. Future cases may cite this to challenge geographic limits in pollution consents, fostering a precedent for nationwide waste flow per Rules. Overall, the decision safeguards trade rights while upholding environmental integrity, likely influencing SPCB policies across India.
