Submission of

1) Compliance Report





A stack of height 50 Meters. Should be installed with continuous on line monitoring system.


The height of the stack of 80 M and Provision is made in every stuck for measuring the emission. There is no on line monitoring system, but the required monitoring instru-ment as suggested by MPCD are kept at site and ready for use by the competent personal as and when desired.


The water to the tune of 1584M3 /d will be drawn from the Tlawng (Dhaleshwari) River.


The cooling system is closed cycle and the water requi-rement/day varies depending on the use of the set. As the DG sets are not operated daily hence the water requirement is very minimal and will be drawn from the near by stream.


Noise level should be limited to 75 d BA and regular Maintenance of equipment be undertaken. For people working in the area of generator halls and other high noise areas, earplug should be provided.

  1. Lining of noise producing equipments with acoustic enclosure
  2. Monitoring of noise level at the time of testing and subsequently at regular interval

Acoustic enclosure is provided noise level is less than 70 d B(A)and earplug is also provided.


Land acquisition should be restricted to 3.57 ha only.

Acquiring land not more than 3.57 ha

Land acquired is less than 3.75ha for the plant alone but the total land acquired including land for accommodation of staff quarter is more than 3.75 ha. There is no proper record of land  acquisition as some portion of land are donated by the local people


A forestation should be under taken covering an area of 0.46 ha around the plant. A norm of 1500-2000 trees per ha. Should be followed as per CPCB quidelines. Compensatory a forestation should also be carried out in lieu of diversion of forest land as per the proposal approved by Forest Department.

1) Planting of seeding and maintain during 2003 to 2004 and around the plant

Planting of seedlings of about 800 No’s done at present which are about 4-5mtrs. Compensa-tory a forestation is not requi-red as the site is previously utilized for cultivation.


Heavy fuel oil should be used as main feedstock @ 106.56TPD. The sulphur contents, in the fuel should not exceed 0.75%


Analysis of sulphur content of HFO (Heavy fuel oil) submit-ted by Indian Oil Corporation Ltd is enclosed herewith.


All effluents generated in various plant activities should be collected in the central effluent Treatment plant central monitoring Basin and treated to ensure adherence to specified standards of usage for the green belt development and other proposed activities.




Same as  No 1(g)

Sub No (2)

As mentioned above the system is enclosed circuit cooling system and the effluent will be negligible.


Regular monitoring for SPM,502 and Nox around the Power plant may be carried out and records maintained. Monitoring stations should be established in consultation with the state pollution control Board.

  1. Identification of station.


  1. Regular monitoring

High volume sampler, stack monitoring kit (Handy stack samples and stack velocity monitor) and noise meter  are already purchase and kept at the plant site we have already inform the arrival  of those instrument but not yet make programme for installation of monitoring station.


Total  debris generated to the tune of 75,000m3 should be fully utilized for filling low lying area within core zone and for filling to create levels for construction.

Collection and deposition of all debris at the specified location.

All the debris generated are negligible which are properly utilized for filling the low lying area. Therefore there further debris once the land is leveled.


Risk analysis report should be prepared and the disaster management plan should incorporate emergency plan. This report should be submitted in this ministry within two months of the issue of this letter
