Treatment processes required to meet the standards in Table 3.
Prepare a preliminary design of the treatment plant (could be located depending upon topography) if not done so far.
Prepare a rough costing of conveyance and treatment of waste water.
Collect samples of river water from location downstream of discharge, if relevant, determine use of the river stretch, check quality of samples vis-a-vis requirements, estimate consequent to proper CETP.
From the air pollutant load estimated and over meteorological data determine highest ground level concentrations, check with actual field measurement. Determine improvement required in terms of pollutant generation.
Examine where industrial sludges, hazardous wastes, industrial wastes are disposed off; examine the details of disposal practice (may be the relevant industries are disposing the hazardous sludges on their own backyard).
Examine the whole issue - examine possibility of ground water pollution, if possibility exists collect soil, leachate/ground water samples and analyse and interpret data.
Arising out of the impact study, determine mitigation measures required more than the minimum requirement (concept of MINAS).
Degree of treatment required (over and above prescribed) consistent with recipient system requirement, rough estimate of capital cost of conveyance and pretreatment & operation & maintenance cost. Evolve cost sharing formula and administrative arrangement for construction and operating the plant.
Determine location of discharge of treated effluent which will have very low impact on receiving body of water.
Determine stack height requirement, if required in individual cases, examine need for better (low sulphur) fuel oil use, examine non-operation of certain industries during certain time of day/month/season; examine workplace environment in respect of critical pollutants such as chlorine and operations like pesticide formulation.
Identify the wastes that could be disposed of into a landfill. Select the site in and around the Estate; draw specifications for design, construction and operation of the landfill site.
For wastes that could not be disposed into the landfill determine alternatives, including storage in concrete drums.
Prepare a plan for large scale plantations in the Estate. Identify and prepare list of trees, shrubs, herbs (relevant to the area).
Identify any other aspect specific to the estate such as Noise pollution, Smell/odour etc. and prepare/recommend short term and long term measures required.
