New standard for managing contaminated areas: what changes and how does it impact the sector?

Contaminated Site Management: Keys to the Normative Update

Identification and recovery of contaminated areas requires absolute technical rigor. With recent updates from bodies such as CETESB, companies must adopt more precise protocols.

About Contaminated Site Management

Contaminated Site Management (CSM) is a dynamic process aimed at minimizing chemical risks. In the state of São Paulo, this process is governed by State Decree No. 59.263/13 and Decree No. 62.973/17, which regulate soil quality protection and contaminated area management.

Management Process Stages:

Preliminary Assessment: Collection of history and evidence of contamination.
Confirmatory Investigation: Laboratory analysis to confirm substance presence.
Detailed Investigation: 3D delimitation of the contamination plume.
Risk Assessment: Scientific determination of intervention needs.
Intervention and Remediation Plan: Execution of measures for area recovery.

Prepare your company for the ABNT NBR 10004 update

Waste classification regulations in Brazil are undergoing a historic transformation. With the revision of NBR 10004, companies must adopt new technical criteria and legal responsibilities.

About NBR 10004 and its update process

The Brazilian Association of Technical Standards (ABNT) has launched the revision of the ABNT NBR 10004 standard, a pillar originally established in 2004 that defines the criteria for the identification and categorization of solid waste. This update aims to modernize waste management in Brazil by incorporating technological advances and aligning national parameters with international best practices.

What to expect from the new 2024 version?

The revision proposes a structural change in the classification process, which will now consist of 4 critical steps:

Listing Classification: Evaluation according to the new General Waste List (LGR).
Persistent Organic Pollutants (POPs): Evaluation of substances such as Dioxins and Furans, based on international harmonized lists.
Physico-Chemical Properties: Analysis of hazard characteristics (flammability, corrosivity, reactivity).
Toxicity Evaluation: One of the most complex changes, requiring deeper analysis to determine harmful potential.

Changes in Nomenclature and Technical Responsibility

The new standard simplifies the nomenclature to Class 1 (Hazardous) and Class 2 (Non-Hazardous). A fundamental change is the elimination of the solubilization test and the adaptation of leaching protocols. Additionally, the responsibility for issuing the Waste Classification Report will fall to a qualified technical manager.

CEIMIC’s Role in the Normative Transition

At CEIMIC, we have the analytical infrastructure and the expert team needed to guide your company in this new scenario. We perform the 4 required classification steps and provide technical support to interpret the new maximum allowable values.
