Delhi Pollution Control (DPCC)

The Delhi Pollution Control Committee (DPCC) grants Consent to Establish and Consent to Operate under the Water (Prevention and Control of Pollution) Act, 1974 and Air (Prevention and Control of Pollution) Act, 1981, for industrial and commercial units within the National Capital Territory. Because Delhi-NCR enforces some of the country's strictest air-quality rules, DPCC applications are reviewed alongside seasonal GRAP (Graded Response Action Plan) restrictions, and certain manufacturing categories face additional siting scrutiny given the city's dense, mixed-use zoning.

DPCC consent exists to ensure that any unit discharging effluent or emissions within the NCT operates within limits the local air-shed and water bodies can safely absorb — particularly critical given Delhi's already severe air-quality burden.

Consent in Delhi is granted in two stages: Consent to Establish (CTE), sought before construction begins, confirms the proposed unit, its process, and its planned pollution-control infrastructure are acceptable in principle; Consent to Operate (CTO), sought once construction is complete, confirms the actual installed infrastructure — effluent treatment, air pollution control equipment, stack heights — matches what was approved and is functioning before the unit begins commercial operations. Skipping straight to operations without both stages is a common and entirely avoidable compliance gap.

Because Delhi's industrial land is limited and tightly zoned, unit classification (which permitted industrial category and Red/Orange/Green/White pollution category a proposed activity falls under) is often the first real gating question — some manufacturing activities simply aren't permitted in certain parts of the NCT regardless of pollution-control measures, so confirming zoning and category fit before finalising a site avoids a far costlier problem than a slow consent review.
