2 PROPOSED TERMS OF REFERENCES

The following is submitted for consideration of the competent authority:

1. The proposal is for shifting 2 hazardous chemical storage tanks of 3000 m3 from the existing tank

farm area to the new location. This shifting has been necessitated owing to logistical reasons. The

total capacity of all isolated storages sanctioned (7,25,500 m3 over two phases) will not change. The

entire project continues to be within the port area for which both EC as well as CRZ clearance was

received.

2. The information mentioned in S. No. 1 above was submitted to the MoEF as part of the project

documents (Form 1, Public Consultation, EIA Report and Presentations) based on which EC and CRZ

clearance was issued to AHPPL.

3. Owing to S. No. 1 and S. No. 2 above, sufficient additional studies have been done, such as risk profile

for new location of tanks as mentioned in S. No. 1 above – addressed in Annexure 14.

Owing to 1, 2 and 3 above, and owing to the fact that there is no change whatsoever in the total storage

capacity of the tanks, merely re-location, it is submitted that the amendment to the EC be furnished to

AHPPL at an early date, foregoing the exercise of preparing a formal ToR, EIA report and public

consultation since there is no expansion in storage capacity whatsoever.

Annexure 8: Operation Process

Petrochemical industries are setting up a dual feed cracker to produce various building blocks for

downstream petrochemical processing industry.

Butadiene is one of the products and required to be exported. Therefore many companies have

approached AHPPL to create facility at Adani Hazira Port, to handle & storage of Butadiene and facilitates

its exports.

After catering to the local demand surplus is to be exported from AHPPL facility.

The road tankers carries around 15-20 Tonnes of Butadiene and hence it is expected that port may receive

20 to 25 road tankers on daily basis. The road tankers are then unloaded and the material is transferred to

the storage tanks thru pipelines connecting the unloading bays and the storage tanks.

Butadiene will be stored under refrigeration.

The aggregation of 10-15 days quantities will then be shipped or loaded on to the export vessels/ ships. Till

such time butadiene is stored in the suitably designed tanks at AHPPL’s Hazira Port.

The storage tanks are connected to the pumps which are required to pump the material (Butadiene) thru a

pipeline connected to the manifold at the jetty.

Annexure 10: Details of Effluent Treatment Plant and Sewage Treatment Plant

Details of Effluent Treatment Plant

Collection Tank cum Oil Water Separator

The incoming effluent from the tank pumped at the rate of 10 cum/hr and stored here prior to

pretreatment. This is done to meet hydraulic requirement and consistency of flow for further

continuous treatment. Here Primary oil removal facility i.e. mechanical belt type oil skimmer with

baffle is provided. The oil content being considerably high it is further pumped to TPI unit.

Tilted Plate Interceptor

The oily effluent from the collection tank transferred to TPI unit where oil floating at the top is

removed by pipe type skimmer. The effluent is passed through tube pack, where oily water flows

from the top of the pack and then over an effluent weir into the treated water chamber the oil

droplet coalesces into large droplets and float at the top. This oil is removed by means of pipe

type skimmer & will be stored in oil collection tank. The sludge from the TPI unit is feed to

chemical sludge drying beds for dewatering.

Equalization Tank

The aqueous layer with whatever dissolved chemicals and some carryover oil and grease will

overflow to equalization tank. Here aeration is provided to avoid the settlement of any solids and

ensure uniform mixing. Domestic sewage also will be added in this tank by gravity. This provision

is made considering future expansion. Then the effluent from equalization Tank is pumped to

Flash mixing Tank.

Flash Mixer for Lime

The overflow from the equalization tank is pumped to Flash mixing Tank, Where lime and PAC

dosing system is provided for coagulation. Here, the flash mixing is done to ensure the uniform

mixing with the chemicals. From ET pumping main, there is 1 bypass provision to collection tank

to remove the traces of oil and grease present if any.

Flash Mixer for Alum/Neutralization tank

In this tank the effluent is neutralized by means of pH correction dosing system using Alum.

Overflow from flash mixing tank is collected in flocculation tank.

Flocculation Tank

Overflow from the flax mixing tank is collected in the flocculation tank, where floc formation is

aided by addition of polyelectrolyte dosing & slow mixing.

Primary Tube Settler

The primary Tube Settler is proposed to settle out the sludge solids. The flocs formed in

flocculation tank are allowed to settle in primary tube settler for separation of solids and liquids.

The sludge from the primary tube settler is fed to sludge drying beds for dewatering. The dried

sludge disposed of as hazardous waste and sludge filtrate will be returned to equalization tank.

The overflow from primary tube settler will be fed to FAB/MBBR Tank for biological treatment.




FACILITY FORM I


FAB/MBBR Tank

The biological treatment is designed on FAB/MBBR process for optimum utilization of space. The

FAB consist of tank filled with special media. These media are made of specially developed

material of controlled density such that they can be fluidized using an aeration device. A bio film

develops on the media which moves along the effluent in the reactor. The movement within the

rector is generated by providing diffused aeration with the help of diffusers placed at the bottom

of the reactor. The thin bio film on the media enables the bacteria to act upon the biodegradable

matter in the effluent and reduce BOD/ COD content in the presence of oxygen that is used for

fluidization. Urea/ DAP system is provided for nutrient supplement in FAB Tank.

Secondary Tube Settler

The biologically treated effluent from MBBR tank is collected in secondary Tube settler for

separation of solids and liquids. The settled sludge fed to sludge drying beds and supernant will

overflow to chlorine contact tank for disinfection.

Chlorine Contact Tank

The overflow of secondary tube settler is collected into chlorine contact tank. For disinfection of

water sodium hypo chloride solution is fed from sodium hypo tank by means of electrical metering

pump, which doses proportionately to the inflow of water. Then disinfected effluent further

pumped through dual media filter for tertiary treatment.

Dual Media Filter

The objective of Dual Media Filter is to remove suspended solids free chlorine, organic matter,

odour and colour from water. Activated carbon filters are very effective and produce best quality

water when operated properly. The filter media consists of gravel bed support at bottom and

activated carbon media at top. The treated effluent then collected in treated water storage tank.

Treated Water Storage Tank

The tertiary treated effluent is stored into this tank prior to disposal of the effluent by means of

transfer pumps.

Sludge Drying Bed (Chemical)

The sludge from the primary tube settler and TPI is fed by gravity under hydrostatic head to

sludge drying beds for dewatering. The filtrate is returned back to Equalization tank and sludge is

disposed of as hazardous waste.

Sludge Drying Bed (Biological)

The part of sludge from secondary tube settler is pumped to FAB/ MBBR tank to maintain desired

MLSS concentration in FAB/ MBBR tank as return sludge (Optional) while excess sludge will be fed

to Sludge Drying Beds for dewatering and the dried sludge can be removed intermittently for

disposal. Sludge filtrate returned to equalization tank.
