# The Environmental Quality Act 1974: Malaysia's Core Environmental Law

> The Environmental Quality Act 1974 (Act 127) is the backbone of pollution control in Malaysia, run by the Department of Environment through licensing, prescribed premises and EIA. Amendment Act A1712, in force 7 July 2024, lifted maximum fines to RM10 million and made several offences carry mandatory imprisonment.

A single spill into a river in Malaysia can now cost a company up to RM10 million and put the person responsible behind bars — and unlike before, the judge no longer has the discretion to hand down a fine alone. That shift, effective 7 July 2024, is the sharpest change to Malaysia's environmental law in half a century, and it sits inside a statute most operators have lived with quietly since 1974.

The Environmental Quality Act 1974 — "Act 127" in the Laws of Malaysia — is the framework almost every other piece of Malaysian environmental regulation hangs off. If your business emits to the air, discharges effluent, stores or treats scheduled waste, burns anything in the open, or develops land at scale, this Act reaches you. Here is how it works, and what the 2024 amendment changed.

## What is the Environmental Quality Act 1974, and who runs it?

Act 127 is Malaysia's central pollution-control statute. Rather than banning industry, it channels it: activities that could harm the environment are made lawful only under a permit, a licence, or an approved assessment, and doing them without that authorisation is a criminal offence.

The Act is administered by the **Department of Environment (DOE / Jabatan Alam Sekitar)**, headed by a **Director General of Environmental Quality**. The Director General is the pivot of the whole system — issuing licences, approving Environmental Impact Assessment reports, serving notices and prohibition orders, and compounding offences. Enforcement officers act under the Director General's delegated authority.

The Act operates through four main control mechanisms:

- **Emission and discharge controls** — sections prohibiting pollution of the atmosphere (s.22), noise pollution (s.23), pollution of the soil (s.24), pollution of inland waters (s.25), and discharge of oil (s.27) and wastes (s.29) into Malaysian waters, each unless done under licence or within prescribed limits.
- **Licensing of "prescribed premises"** — under section 18, certain premises may not be occupied or operated without a licence from the Director General.
- **Environmental Impact Assessment** — under section 34A, "prescribed activities" must have an approved EIA report before any approving authority can green-light the project.
- **Scheduled (hazardous) waste control** — the storage, transport, treatment and disposal of scheduled waste is regulated through subsidiary regulations and enforced under the Act.

Everything below builds on those four pillars.

## What changed on 7 July 2024?

The **Environmental Quality (Amendment) Act 2024 (Act A1712)** is the most significant overhaul of Act 127 in decades. Its timeline is worth pinning down because compliance dates turn on it:

- **Royal Assent:** 27 May 2024
- **Published in the Gazette:** 6 June 2024
- **Came into operation:** 7 July 2024, appointed by notification **P.U.(B) 243/2024** dated 3 July 2024

The amendment does three things at once. It **raises penalties** across almost every offence — many maximum fines jumped by an order of magnitude. It **converts several offences to mandatory imprisonment**, removing the option of a fine-only sentence. And it **rewrites the open-burning regime**, inserting a statutory definition of "open burning" and substituting a tougher section 29A.

A saving provision (s.30 of A1712) preserves the old law for any action, investigation or proceeding already pending before 7 July 2024 — so conduct before that date is judged under the earlier penalties, and conduct on or after it under the new ones.

## How much higher are the penalties now?

The headline figure — RM10 million — attaches to the offences the legislature treats as most damaging: polluting inland waters, discharging oil or waste into Malaysian waters, and mishandling scheduled waste. But the increases run across the board. The table below maps the main offences to their **current** penalties under Act A1712, with the pre-amendment maximum where a source stated it.

| Offence (section) | Previous maximum fine | Current penalty under Act A1712 |
|---|---|---|
| Breach of licence condition (s.16) | — | RM25,000–RM250,000, or up to 5 yrs, or both; +RM1,000/day |
| Operating prescribed premises without licence (s.18) | — | RM25,000–RM250,000, or up to 5 yrs, or both; +RM1,000/day |
| Pollution of the atmosphere (s.22) | Up to RM100,000 | RM10,000–RM1,000,000, or up to 5 yrs, or both; +up to RM1,000/day |
| Noise pollution (s.23) | Up to RM100,000 | RM10,000–RM250,000, or up to 5 yrs, or both; +up to RM1,000/day |
| Pollution of the soil (s.24) | Up to RM100,000 | RM50,000–RM500,000, or up to 5 yrs, or both; +up to RM1,000/day |
| Pollution of inland waters (s.25) | Up to RM100,000 | **Mandatory** imprisonment up to 5 yrs **and** RM50,000–RM10,000,000 |
| Discharge of oil into Malaysian waters (s.27) | Up to RM500,000 | RM100,000–RM10,000,000, or up to 5 yrs, or both |
| Discharge of wastes into Malaysian waters (s.29) | Up to RM500,000 | RM50,000–RM10,000,000, or up to 5 yrs, or both |
| Open burning (s.29A) | — | RM25,000–RM1,000,000, or up to 5 yrs, or both; +up to RM5,000/day |
| Contravening EIA requirement (s.34A) | Up to RM100,000 | **Mandatory** imprisonment up to 5 yrs **and** RM100,000–RM1,000,000 |
| Breach of stop-work order (s.34AA) | — | **Mandatory** imprisonment up to 5 yrs **and** RM100,000–RM1,000,000 |
| Scheduled-waste offences (s.34B) | Up to RM500,000 | **Mandatory** imprisonment up to 5 yrs **and** RM100,000–RM10,000,000 |

Current figures are taken from the text of Act A1712; the "previous maximum" column reflects figures reported by Enviliance ASIA and is provided only for comparison. Two patterns are worth noticing. First, most offences now carry a **minimum** fine as well as a maximum — the court can no longer impose a token sum. Second, the **daily continuing-offence fine** (RM1,000 a day for most breaches, RM5,000 a day for open burning) means an uncured problem compounds every day after the Director General's notice.

## Which offences now put someone in jail, not just out of pocket?

For most of Act 127's history, imprisonment was an alternative the court "may" impose. Act A1712 flips that for the gravest offences: the statute says the offender "shall … be punished with imprisonment" **and** be liable to a fine. That mandatory-jail category now includes:

- **Pollution of inland waters** — section 25(3)
- **Contravening the EIA requirement** — section 34A(8)
- **Scheduled-waste offences** — section 34B(4)
- **Breach of a prohibition or stop-work order** relating to prescribed activities — section 34AA(3)
- **Breach of an air-pollution prohibition order** — section 31A(3)

For directors, plant managers and named responsible officers, this is the single most important practical change. A negotiated fine is no longer the ceiling of exposure on these offences.

## Which activities need an Environmental Impact Assessment?

An EIA is the front-end control: it happens *before* a project is approved, not after it pollutes. Under section 34A, anyone intending to carry out a **prescribed activity** must submit an assessment report to the Director General, and the project's approving authority may not grant approval until that report is approved.

Prescribed activities are listed in the **Environmental Quality (Prescribed Activities)(Environmental Impact Assessment) Order 2015**. The categories span the heavy-footprint sectors of the economy — among them agriculture, drainage and irrigation, land reclamation, fisheries, forestry, housing, infrastructure, ports, mining, petroleum, power generation, quarries, railways, transportation, resort and recreational development, and waste treatment and disposal. Whether a specific project is caught usually depends on **thresholds** (for example a project's size, capacity or proximity to sensitive areas) set in the Order.

A useful way to picture the two-tier structure:

| | First Schedule activities | Second Schedule activities |
|---|---|---|
| Assessment depth | Standard EIA report | More detailed EIA |
| Public display & comment | Not required unless the Director General directs it in writing | Required — the report is displayed for public comment |
| Typical footprint | Lower-impact prescribed projects | Higher-impact prescribed projects |

The practical takeaway: check the EIA Order 2015 against your project scope *early*, because an approved EIA is a precondition to the downstream approvals (planning, manufacturing licence, and so on), and starting a prescribed activity without one is a mandatory-imprisonment offence.

## Do I need a licence to operate — the "prescribed premises" question

Separate from the EIA is the licensing of **prescribed premises** under section 18. The Minister prescribes categories of premises whose operation is controlled — historically these include crude palm-oil mills, raw-natural-rubber processing, and scheduled-waste treatment and disposal facilities. For prescribed premises there are typically two consents: **written permission to construct**, and a **licence to occupy or operate**. Operating without the required licence, or breaching a licence condition (s.16), is now an offence of RM25,000 to RM250,000 or up to five years, plus RM1,000 for each day it continues after the Director General's notice.

## How do I work out which EQA duties apply to my project?

Use this decision path. It is a triage tool, not legal advice — confirm the detail against the Act, the EIA Order 2015 and the DOE's guidance for your sector.

1. **Are you developing or expanding a physical project?** Cross-check it against the **EIA Order 2015**. If it is a prescribed activity, you need an approved **EIA report** (s.34A) *before* seeking project approval. If it is a Second Schedule activity, budget for a public-display period.
2. **Will you operate premises in a prescribed category** (e.g. palm-oil, rubber, scheduled-waste facilities)? If yes, obtain **written permission to construct and a licence to operate** under section 18.
3. **Will you emit to air, water or soil, or generate noise?** You must stay within licence limits or prescribed standards; uncontrolled discharge triggers sections 22–25.
4. **Will you generate scheduled (hazardous) waste?** The scheduled-waste regime applies — storage, labelling, transport by licensed contractors, and disposal at licensed facilities. Breaches now sit in the RM10 million / mandatory-imprisonment band (s.34B).
5. **Do your operations involve any burning?** After the 2024 amendment, **open burning is prohibited** on any premises unless specifically excluded by Ministerial order (s.29A).
6. **Discharging near or into the sea?** Sections 27 and 29 (oil and wastes into Malaysian waters) apply, with fines up to RM10 million.

If you answered "yes" to any of these, build the corresponding consent or control into your project programme before you break ground or start operating.

## What are the most common EQA compliance mistakes?

- **Treating the EIA as a formality to be done later.** It is a *pre-condition* to approval. Starting a prescribed activity before the EIA is approved is now a mandatory-imprisonment offence.
- **Assuming a fine is the worst case.** For inland-water pollution, EIA breaches, scheduled-waste and stop-work-order offences, the court must impose imprisonment as well as a fine.
- **Ignoring the daily continuing-offence fine.** After a Director General's notice, RM1,000 (or RM5,000 for open burning) accrues for each day the breach is not cured — a delayed fix can dwarf the base fine.
- **Confusing the EIA with the operating licence.** They are different consents under different sections (34A vs 18). You can need both.
- **Open burning of site or agricultural waste.** The 2024 amendment tightened the definition and the prohibition; "we've always burned it here" is not a defence.
- **Using unlicensed scheduled-waste contractors.** Liability for mishandled hazardous waste flows back to the generator, and the penalty band is now the highest in the Act.
- **Forgetting the saving provision.** Conduct before 7 July 2024 is judged under the old penalties; conduct on or after it under the new ones. Do not assume the higher fines apply retroactively — or that the old lower ones still shield current conduct.

## What's next

If any of the triggers above apply to your operations, three moves are worth making now. First, map your activities against the EIA Order 2015 and the prescribed-premises categories, and confirm every consent you rely on is current. Second, brief directors and responsible officers specifically on the **mandatory-imprisonment offences** — these change the personal-liability calculus, not just the corporate one. Third, tighten the paper trail around scheduled waste and any Director General notices, because the daily continuing-offence fines reward fast remediation and punish delay.

For sector-specific detail, the Department of Environment publishes guidance for investors and EIA guidelines at doe.gov.my, and the full texts of Act 127 and Amendment Act A1712 are the authoritative reference. Where a project's classification or a penalty exposure is genuinely uncertain, a short consultation with an environmental-law practitioner is far cheaper than a RM10 million ceiling.
