Hazardous and Other Wastes Amendment Rules 2026: Brine Sludge Removed from Schedule I

The Ministry of Environment, Forest and Climate Change issued the Hazardous and Other Wastes Amendment Rules 2026 on 16th July 2026. The notice amends the Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016. Essentially, "Brine Sludge" has been deleted from Schedule I of the aforementioned rules, which comes under Process No. 16: Production of caustic soda and chlorine. It is important for industries that manufacture caustic soda, as well as chlor-alkali plants seeking SPCB CTO amendment for waste reclassification or MoEFCC notification advisory services, to note this amendment. This article discusses the implications of the Hazardous and Other Wastes Amendment Rules 2026, reasons for the amendment, regulatory requirement for Schedule 3 hazardous waste testing, and steps forward for SPCB compliance.  

Background of the Regulatory Framework

The management of hazardous wastes in India is done by means of the Hazardous and other Wastes (Management and Transboundary Movement) Rules, 2016. These rules have been formulated in accordance with the provisions of the Environment (Protection) Act, 1986. They provide guidelines to industries for the handling and disposal of such wastes.

The Rules were introduced because industrial waste, if left unmanaged, can pollute soil, water, and air. Some waste is toxic. Some is corrosive. Some can catch fire. The Rules give this waste a legal category so that everyone follows the same safety standard.

Schedule I of these Rules lists processes that generate hazardous waste. Each process has a list of waste types linked to it. If your waste appears in Schedule I, you must follow strict rules for its handling.

Hazardous waste is identified in two ways. First, by the process that creates it, listed in Schedule I. Second, by its hazardous characteristics, such as toxicity or corrosivity, listed in Schedule III. A waste is treated as hazardous if it matches either list.

Different types of wastes are significant because different risks are associated with them. Different storage is required for corrosive waste when compared to flammable waste. Inappropriate handling could lead to fire, leakage, and hazards to workers.

Industries that generally follow these Rules:

• Chemical manufacturing units
• Chlor-alkali and caustic soda plants
• Pharmaceutical companies
• Metal processing and electroplating units
• Petroleum and refining industries
• Waste treatment, storage, and disposal facilities

Key takeaway: Schedule I is the list that classifies whether industrial waste is considered to be hazardous or not.

What Was the Earlier Provision?

Before this amendment, Schedule I listed "Production of caustic soda and chlorine" as Process No. 16. Under this process, entry 16.3 named "Brine Sludge" as a hazardous waste.

Brine sludge is a waste that forms during the chlor-alkali process, where salt water (brine) is used to make caustic soda and chlorine. This sludge can contain impurities separated during purification of the brine.

Because Brine Sludge was listed in Schedule I, any factory producing it had to treat it as hazardous waste. This meant the factory needed authorisation to store it, had to use approved disposal methods, and had to maintain detailed records.

Think of Schedule I as a checklist. If your waste name is on the list, you must follow hazardous waste rules for it, no matter how small the quantity.

Under the earlier position, a caustic soda plant could not treat brine sludge as ordinary industrial waste. It had to follow the full hazardous waste compliance chain, from generation to final disposal.

What Has Changed Under the 2026 Amendment?

The Hazardous and Other Wastes Amendment Rules 2026 make one precise change. In Schedule I, under Process No. 16 ("Production of caustic soda and chlorine"), the entry "16.3 Brine Sludge" has been omitted.

This notification has touched no other entry, process, or Schedule. The scope of the amendment is narrow and specific to this single line item.

The notification does not modify any other process, waste category, or compliance requirement elsewhere in the 2016 Rules.

Why Has the Government Made This Change?

The notification itself does not give a detailed explanation for why Brine Sludge was removed. It only states that the amendment is being made in the public interest, which is the standard legal language used to skip the usual public notice period under Rule 5(3)(a) of the Environment (Protection) Rules, 1986.

Since the notification does not spell out the scientific or technical reasoning, this article will not guess at unstated reasons. What can be reasonably said, based on how such Schedule I updates usually work, includes:

• Regulatory review: The Ministry periodically reviews me entries based on technical inputs.
• Possible reclassification: The waste may now be assessed differently, or handled under a different regulatory category.
• Simplification intent: Removing a specific entry can reduce overlap or confusion in classification.
• Administrative correction: Sometimes single-line changes correct outdated or narrowly applicable entries.

The notification does not confirm any of these as the actual reason. Businesses should not assume Brine Sludge is now completely free of environmental obligations. The removal is limited to its Schedule I listing.

Legal Basis of the Amendment

This amendment draws its authority directly from the Environment (Protection) Act, 1986. Specifically, Sections 6, 8, and 25 of the Act give the Central Government power to frame and amend rules for hazardous substances and waste management.

The notification is read together with sub-rule (4) of Rule 5 of the Environment (Protection) Rules, 1986. This sub-rule allows the government to skip the usual public notice requirement under Rule 5(3)(a) when it decides that doing so serves the public interest.

That is why this amendment was notified directly, without a prior draft-notification and public comment stage, which is otherwise common for rule changes.

What Does Removal of Brine Sludge Mean?

For caustic soda and chlorine manufacturers, this change means Brine Sludge is no longer automatically classified as hazardous waste under Schedule I, Process 16.

However, what does not change is the environmental responsibilities of a factory at large. The general responsibilities in terms of the Environmental Protection Act, pollution control board permission, and other such environmental regulations remain intact despite this modification.

However, in case Brine Sludge exhibits any of the characteristics specified under Schedule III of the same rules, such as being toxic or corrosive, the substance can still be considered hazardous waste based on those characteristics. The notification only revokes its Schedule I process classification.

Other obligations that may continue include state pollution control board reporting, safe storage practices as a matter of good industrial hygiene, and compliance with any state-level directions.

Myth vs Fact

Industries Likely to be Affected

This amendment primarily affects the chlor-alkali sector, but its ripple effect touches related service industries too.

Caustic soda plants and chlor-alkali units are the most directly affected, since Brine Sludge was specifically tied to their manufacturing process.

Impact on Businesses

Businesses generating Brine Sludge should review several operational areas after this amendment.

• Documentation: Update internal hazardous waste registers to reflect the removal of this entry.
• Waste handling: Reassess if Brine Sludge still needs hazardous-waste-level handling based on its actual characteristics.
• Disposal: Check whether current disposal contracts and facilities remain appropriate.
• Storage: Storage practices may be simplified, but safety standards should not be lowered without technical assessment.
• Transportation: Manifest and transport documentation tied to Schedule I classification may no longer be mandatory for this specific waste.
• Cost: Businesses may see lower compliance costs if hazardous-waste-specific handling is no longer required.
• Record keeping: Historical records should still be retained for audit purposes.

Implementation Timeline and Effective Date

The Hazardous and Other Wastes Amendment Rules 2026 came into force immediately on publication.

Compliance Checklist for Industries

• Use this checklist to review your current position after the amendment.
• Review your hazardous waste inventory for Brine Sludge entries
• Check if Brine Sludge still meets Schedule III hazard characteristics
• Update internal waste classification records
• Review disposal and transport contracts linked to this waste
• Check existing authorisations issued by the State Pollution Control Board
• Inform your compliance and EHS team about the change
• Maintain historical records of past hazardous waste handling
• Consult an environmental expert before changing disposal practices

How Businesses Can Achieve Compliance?

Step 1: Identify affected waste streams. Check your process flow to confirm whether Brine Sludge is generated at your facility under Process 16.

Step 2: Test waste characteristics. Get your Brine Sludge tested against Schedule III parameters to confirm if it still qualifies as hazardous on other grounds.

Step 3: Update internal records. Amend your hazardous waste register and Form 3 or Form 4 filings, if applicable, to reflect the current status.

Step 4: Review contracts with disposal facilities. Speak to your authorised treatment, storage, and disposal facility about any changes needed in your agreement.

Step 5: Inform your State Pollution Control Board. If your current permit specifies Brine Sludge, find out if an amendment is required.

Step 6: Train your compliance team. Ensure that your EHS personnel and plant managers are aware of the changes to the classification of sludge.

Benefits for Businesses

Simpler Compliance for One Specific Waste Stream

• Facilities no longer need to route Brine Sludge through the full hazardous waste compliance chain by default
• Fewer approvals and permissions are needed specifically for this waste category
• Internal EHS teams can spend less time managing a stream that previously demanded constant oversight

Greater Clarity on What Falls Under Schedule I Today

• Businesses get a clearer, updated picture of exactly which processes and wastes remain regulated.
• Removes ambiguity that existed when a waste stream sat in a grey zone between routine industrial waste and hazardous waste
• Helps compliance teams avoid over-classifying waste out of caution, which often adds unnecessary cost

Less Paperwork if Brine Sludge No Longer Needs Hazardous Waste Manifests

• Movement of this waste may no longer require hazardous waste transport manifests
• Reduces the volume of tracking forms, trip sheets, and consignment notes tied to this specific stream
• Cuts down on repetitive filing that added little value once the waste no longer needs process-based classification

Easier Documentation and Lower Administrative Load

• Fewer hazardous waste registers and periodic returns to maintain for this entry
• Simplifies annual reporting to the State Pollution Control Board where this waste was previously listed
• Frees up compliance staff to focus on higher-risk waste streams that genuinely need close monitoring

Better Long-Term Planning Once Classification Is Settled

• Gives plant operations teams a stable basis to plan storage space, disposal contracts, and budgets
• Reduces uncertainty in vendor agreements with waste treatment and disposal facilities
• Supports more accurate cost forecasting once businesses know which obligations genuinely apply going forward

Key Compliance Risks to Watch

Is This the Right Decision or an Additional Burden?

Removing Brine Sludge from Schedule I is a small change on paper, but it raises a fair question for the industry it touches.

The amendment is narrow and does not remove environmental responsibility altogether. Whether it turns out to be a genuine simplification or a source of fresh compliance questions will depend on how individual facilities and State Pollution Control Boards apply it in practice.

Business Opportunities Created

• Compliance consultants can help chlor-alkali units reassess their waste classification correctly.
• Waste management companies may see demand for updated handling protocols.
• Environmental testing laboratories can offer Schedule III characteristic testing services.
• Recycling businesses may explore new avenues if Brine Sludge is now easier to process outside hazardous waste channels.
• Sustainability consultants can guide companies on responsible handling even where hazardous classification no longer strictly applies.
