Environmental Assessments
Environmental Assessments

The National Environmental Management Act of 1998 (NEMA) through its regulations have identified a range of listed activities or actions that will require some type of environmental authorisation due to the likely impact these types of activities may have on the environment.

The listed activities are divided into two main categories, with small or low impact activities, or those which take place in sensitive environments in certain provinces, requiring a Basic Assessment, and medium or larger scale activities, requiring a comprehensive Environmental Impact Assessment.

Basic Assessments

Basic Assessments are required for all activities listed in terms of NEMA. They require investigation as well as a public participation process in order to allow the competent authority to make an informed decision.

Generally Basic Assessments consist of an informed assessment of the environmental attributes of the area under consideration, an analysis of the likely impacts that the proposed development may have, and suggested mitigation measures to reduce any impacts. A Basic Assessment is effectively a small Environmental Impact Assessment, sometimes supported by one or more specialist studies.

Environmental Audits and Performance Assessments

Whenever a developer intends to initiate a particular activity or project, buy an operating company, or purchase a tract of land that may have been subject to past environmental impacts, an environmental screening or risk assessment can be undertaken.
Such an undertaking may involve a preliminary screening exercise to determine the level of investigation required, or form part of a detailed due diligence exercise to inform the prospective developer or purchaser of any inherent or latent environmental risks or pollution associated with a proposed course of action.

This latter work often requires specialist investigation to determine the magnitude of the risks and any necessary rehabilitation measures and costs to eliminate or reduce these risks.

As part of the environmental due diligence (EDD) of a project, we systematically review and identify environmental issues that present risks or liabilities to operations for the purpose of acquisitions, mergers, unbundling, or restructuring activities.

Environmental Impact Assessment

An environmental impact assessment (EIA) is an assessment of the possible positive or negative impact that a proposed project may have on the environment, together consisting of the natural, social and economic aspects.

The purpose of the assessment is to ensure that decision makers consider the ensuing environmental impacts when deciding whether to proceed with a project. The International Association for Impact Assessment (IAIA) defines an EIA as “the process of identifying, predicting, evaluating and mitigating the biophysical, social, and other relevant effects of development proposals prior to major decisions being taken and commitments made.”.

The EIA report is underpinned by various specialist environmental studies — depending on the proposed activity being investigated — and a transparent, robust and inclusive public participation process. Prescali Environmental Consultants (Pty) Ltd draw on a wide pool of expertise, most of whom are considered leaders in their fields, which enables us to tailor specialist teams according to the specific needs of each client or project.

Environmental Audits and Performance Assessments

Environmental Auditing / Performance Assessment involves measuring the level of compliance of a specific activity, development or project against a set of standards (e.g. ISO 14001), legislation, management plan or permits/licences.  Audits must be objectives, impartial and independent and the audit process must both be systematic and documented. It is an environmental management tool which are used to assess, evaluate and manage environmental and sustainability issues through a systematic process that must be carefully planned, structured and organised.

The overall objective is to be able to monitor performance over time and assess whether or not compliance has improved or not. Audits also provide a forum for the exchange of technical knowledge and identification of cost reductions.

Legislation requires that an EIA be undertaken for many developments particularly where there is the potential for significant environmental effects and Prescali Environmental Consultants (Pty) Ltd through the fact that we are highly skilled and experienced in the co-ordination and management of the EIA process at all levels, we can advise on the need for a Basic Assessment or Environmental Impact Assessment.

Environmental Control Officer

An Environmental Control Officer (ECO) fulfils the function of an independent monitor of the implementation of the Environmental Management Program (EMP) and monitors all relevant environmental aspects on site.

The ECO needs to form part of the project team, being involved in all aspects of the project planning that can influence environmental conditions on site, i.e. attending relevant project meetings, conduct inspections to assess compliance with the Environmental Management Program and be responsible for providing feedback on potential environmental problems associated with the development. In addition, the ECO’s responsibility includes:

  • Liaising with pertinent governments departments and submit environmental audit reports in terms of the level of compliance to the EMP
  • Liaising with contractors, engineers and the design team regarding environmental management
  • Liaison with Interested and Affected parties, if and when required
  • Routine monitoring and reporting as per the site specific checklist

The ECO has the right to enter the site and undertake monitoring and auditing at any time, subject to compliance with health and safety requirements applicable to the site (wearing safety boots, head gear, mouth mask etc).

Although the main aim of the ECO report is to report on the compliance with the EMP, the report will also include a description of the general state of the site, with specific reference to legal non-compliance. Corrective action measures will be suggested to eliminate the occurrence of the non-compliance incidents. In order to keep a record of any impacts, an Environmental Log Sheet needs to be kept on a continual basis.
