Environmental Impact Assessment (EIA) Services

Overview 

We specialize in offering detailed, technically robust, and regulatory-compliant Environmental Impact Assessment (EIA) services. Our expertise spans across high-stakes industries including petroleum refineries, synthetic chemical plants, infrastructure development, and thermal power generation. We assist clients in meeting the statutory requirements under the Environmental Impact Assessment Notification, 2006, and its subsequent amendments issued by the Ministry of Environment, Forest and Climate Change (MoEFCC). 

As a NABET (QCI) accredited Category A Consultant, we deliver end-to-end EIA solutions from scoping and data collection to predictive modelling, public consultation, risk assessments, and post-clearance environmental monitoring. We ensure all EIA deliverables are aligned with national and international standards, including ISO 14001:2015 (Environmental Management Systems) and ISO 31000:2018 (Risk Management) to integrate sustainability, safety, and regulatory compliance.

Our Process Framework (EIA Lifecycle) 

1. Screening & Site Analysis – Determines if the project requires EIA based on thresholds under the Schedule of EIA Notification, 2006. This includes the identification of sensitive environmental receptors and preliminary land use compatibility. 
2. Scoping & Terms of Reference (ToR) – The proponent submits Form I and a Pre-Feasibility Report to MoEFCC or SEIAA for scoping. ToR defines the scope, extent, and methodology of the EIA study. Customized ToRs are often issued, including directives for QRA, greenbelt, water budgeting, etc. 
3.  Baseline Data Generation – A one-season primary data collection campaign covers environmental components (air, water, noise, soil, biodiversity, socio-economics) using approved methodologies and calibrated instruments. 
4. Impact Assessment & Modelling – Impacts from project activities are identified and predicted. This includes pollutant dispersion modelling (air/noise/water), risk mapping, resource consumption analysis, and social impact evaluation. Severity, duration, and reversibility of each impact are assessed. 
5. Mitigation & EMP Formulation – Technical solutions are proposed to mitigate negative impacts and enhance positive ones. EMP includes specifications for treatment technologies, greenbelt design, monitoring frequency, and institutional responsibilities.
6. Draft EIA & Public Consultation – Draft report is submitted to the State Pollution Control Board (SPCB) for public hearing. Issues raised are documented, addressed, and incorporated into the final EIA.
7. Final EIA Submission & Appraisal – Final report includes all baseline data, modelling results, stakeholder feedback, EMP, and cost analysis. Submitted to the Expert Appraisal Committee (EAC) for scrutiny.
8. Environmental Clearance (EC) & Compliance Monitoring – On approval, EC is granted with specific conditions. Post-clearance, half-yearly compliance reports, environmental statements, and monitoring data are submitted. Audits and OHS reports are also prepared.
