In the aftermath of a existent property task that has travel up allegedly wrong the Pallikaranai marshland — 1 of Chennai’s astir ecologically delicate zones and a Ramsar-notified wetland — questions person surfaced astir however ample projects get biology approvals. Public cognition astir who grants clearances is alternatively murky, and not ever accurate, portion the existent process is layered and good documented successful the instrumentality of the land.
The Brigade Group’s lodging project, which, according to the non-governmental organisation Arappor Iyakkam, obtained clearances contempt being wrong the limits of the protected site, has turned the spotlight connected the strategy that decides erstwhile and however specified permissions are granted.
Under the Environment Impact Assessment (EIA) Notification, 2006, issued nether the Environment (Protection) Act, immoderate task that could importantly change onshore usage oregon impact air, water, oregon ecosystems indispensable get anterior Environmental Clearance (EC). This includes ample lodging projects, concern estates, powerfulness plants, mines, and infrastructure specified arsenic ports, airports, and highways. For instance, immoderate residential oregon commercialized improvement with a built-up country of 20,000 quadrate metres oregon much requires clearance earlier construction.
Approval process
Projects are categorised based connected their size and impact. Category A projects — usually ample oregon located successful delicate areas specified arsenic nationalist parks oregon coastal zones — are appraised astatine the nationalist level by the Ministry of Environment, Forest and Climate Change (MoEF&CC). Smaller Category B projects are cleared astatine the authorities level by the State Environment Impact Assessment Authority (SEIAA), which relies connected the method appraisal of its State Expert Appraisal Committee (SEAC).
The process begins with the submission of task details, followed by screening and scoping by the appraisal committee to determine the studies required. A elaborate Environmental Impact Assessment (EIA) study is past prepared, and a nationalist proceeding is conducted successful the projected task area. The committee reviews the findings and submits its recommendation, aft which the SEIAA oregon the MoEF&CC issues the last clearance, often with conditions specified arsenic discarded management, flood mitigation measures oregon maintaining greenish cover.
Approving authorization for biology clearance
Environmental clearances are usually valid for 7 years and indispensable beryllium renewed if the task is delayed. In the lawsuit of ample lodging projects similar the 1 adjacent Pallikaranai, SEIAA–Tamil Nadu is the approving authority. The SEIAA is headed by a elder biology adept oregon retired bureaucrat nominated by the State authorities and notified by the Centre, on with 2 different members who measure proposals based connected method and ecological considerations.
CRZ clearance
For projects adjacent the coast, the Coastal Regulation Zone (CRZ) Notification, 2019, applies. It regulates activities wrong 500 metres from the High Tide Line and on tidal h2o bodies specified arsenic creeks and estuaries. Projects specified arsenic resorts, ports, pipelines, roads, and powerfulness plants wrong these areas request CRZ clearance.
The State Coastal Zone Management Authority (SCZMA) — successful Tamil Nadu’s case, the TNSCZMA — examines the determination of the task and determines whether it falls wrong the regulated coastal portion utilizing approved maps. The connection is past sent to the MoEF&CC for last support if it involves large operation oregon lies successful the astir delicate CRZ-I category. In the Pallikaranai case, CRZ rules are not straight applicable since the wetland lies inland, but for developments on Chennai’s coast, specified clearances are mandatory.
Forest clearance process
Projects involving wood onshore necessitate anterior support nether the Forest (Conservation) Act, 1980. Any diversion of onshore recorded arsenic wood — whether reserve forest, protected forest, oregon deemed wood — indispensable beryllium cleared by the national authorities earlier being utilized for non-forest purposes. The proponent indispensable taxable the connection to the State Forest Department on with onshore details and a compensatory afforestation plan.
After State-level scrutiny, the connection is sent to the MoEF&CC’s Forest Conservation Division. Projects involving smaller areas (up to 40 hectares) are usually cleared by the ministry’s determination office, portion larger oregon ecologically delicate proposals are decided by the national ministry itself. Only aft specified clearance tin wood onshore beryllium legally diverted for different uses.
Separately, operation and reclamation are prohibited wrong wetlands and Ramsar sites nether the Wetlands (Conservation and Management) Rules, 2017. Any task projected wrong oregon adjacent specified areas indispensable beryllium referred to the State Wetland Authority and the MoEF&CC for scrutiny.
These layers of support are meant to guarantee that improvement does not compromise ecological stableness oregon worsen the hazard of flooding and situation loss. But gaps successful mapping, mentation of rules, and overlapping jurisdictions often pb to ambiguities successful implementation.
