S.No. 32 of Addendum 1 & Performance summary in

Annexure -3: Treated Water parameters

With this proposed treatment technology for the given feed

parameter, in the outlet of Ultra filtration (UF) the following

treated water parameters in terms of BOD < 5 ppm, COD <

160 ppm & chromium BDL is not achievable. So Kindly

review & reconfirm the treatment scheme.

RFP provisions shall prevail.

Please refer to the process flow

diagram (and also to Addendum 1

part 2 page 16 of 64) which

describes the indicative step wise

treatment achieved at each

process stage.

2 Addendum – I 12 of 24 S.No. 32: Effluent Quality Requirement

During O&M If CETP receives the effluent of > 13000 ppm

TDS from any of 380 industries, then the contractor cannot

achieve the treated water guarantee of TDS (<2100ppm). In

this case if UPPCB/CPCB initiating any action for not

meeting discharge norms JTETA will take the responsibility

and will take the necessary action against the individual

tannery who discharged more than the norms. Kindly

confirm.

3 Addendum – I 12 of 24 S.No. 32: Effluent Quality Requirement

In any case the effluent of > 13000 ppm TDS is taken in to

the CETP process, then as per the” KPI and non-

conformance criteria” the bidder is not responsible for

guarantee, also bidder can’t meet the UPPCB/CPCB

discharge norms.

In this case noncompliance of UPPCB/CPCB discharge

norms responsibility is with JTETA only. Kindly confirm.

We presumed that after blending with treated sewage if

contractor is not able to get required TDS of < 2100 ppm,

due to > 600 ppm TDS in treated sewage then JTETA will

be responsible for UPPCB/CPCB actions. Kindly confirm.

Please refer to Addendum 2 S.

Damages- Delay

AND

18. Clause 5.4 – Liquidated Damages – Operations

a. Time is the essence of the Contract and the Contractor

shall be liable to Completion of Works of the overall plant as

per the deadline mentioned in the Tender Documents. Since

this is no longer a unit rate contract, we request you to

remove milestone Liquidated Damages for Delay. Hence, if

the overall Completion of Works is delayed beyond the

deadline mentioned for 100% Completion of the Works them

an Amount equivalent to “0.05% of the delayed portion of

the Contract price per day” will be levied capped to 5% of

the Design Build Contract Price.

LD levy for the overall completion period are international

practices and we request you to follow the same. We again

request milestone LD’s not be levied.

Kindly confirm.

b. In International and domestic contracts of this quantum in

size, the liquidated damages for non-performance will be

capped. We hence request you to cap the Liquidated

damages – Operations to 5% of the overall O&M contract

price.

c. In International and domestic contracts of this quantum in

size also cap the aggregated liability for delay and non-

performance to 10% of the overall Contract Price. We hence

request you to cap the aggregated limitation of liability for

Delay and Operations to 10% of the Contract Price.

ARTICLE 2. Payment of O&M Prices

1. Payment of O&M Prices for Operations and

Maintenance of CETP Project

a. JTETA shall pay O&M prices on a Quarterly basis,

(a) We hope you appreciate the fact that the contractor has

to pay salaries and purchase consumables on monthly

basis. Quarterly payment puts a negative cash flow to the

contractor. We hence request you to release O&M

payments monthly.

(b) We also request the O&M payments to be released

within 7 days of submission of Bills. This would enable the

contractor to pay salaries and sub-contractors on time.

(a) RFP provisions shall prevail.

(b) RFP provisions shall prevail.

10 Addendum I 19 of 24

2. Payments for power connection from Electricity Utility

Company

The Contractor shall be responsible for making

payments directly to the Utility Company against all bills

(“Electricity Dues”) for electricity consumed in operation

of the CETP Project,

As you are aware the monthly power consumption charges

for CETPs are huge and if the Contractor is required to pay

these bills and get reimbursement it will result in a huge

negative cash flow. There is also a risk to the contractor that

the funds in the SPV may not be available which will result in

a delay in reimbursement of the power bills. To avoid such a

huge negative cash flow and reduce the risk of delay in

reimbursement, we request the Employer to pay power

charges directly to the Power Utilities to avoid additional

cost if the power charges to be paid by the Bidder.

Key Performance Indicators 180 of 2213. Purity of Sodium Chloride and Sodium Sulphate salt

More than 95% white coloured salt

Please note that purity of salt cannot be guaranteed by any

evaporation process. Inlet concentrate effluent is

evaporated to leave behind the salt crystals. The purity of

salt will hence depend on the inlet effluent quality from the

tanneries. We hence request you to remove the purity of salt

from the KPI and only keep the quantity for the KPI.

RFP provision shall prevail.

Process performance guarantee to be borne by the

Tenderer:

Schedule 8

Liquidated Damages – Operations

Purity of Sodium Chloride and Sodium Sulphate will only

depend on the influent characteristics. Evaporator will only

evaporate water from the concentrate effluent to leave

behind crystallised / amorphous salt.

Organics/Inorganics/Recalcitrant COD that are coloured and

are not oxidised in the aeration will be left behind in the salt.

We hence request you to remove this clause from the

Liquidated Damages.

RFP provision shall prevail.

As you are aware Water Recovery of >95% would

depended on the inlet TDS quantity of the concentrate.

Since inlet TDS levels to the evaporator will be over

50,000ppm, >95% water recovery will not be possible. We

hence request you to keep this value to >95% v/v – based

on pilot plant inlet effluent volume (and not on evaporator

inlet concentrate effluent volume)

88 H2S and Cr concentration in air

Based on the ambient air analysis in the proposed site, the

H2S Level in the ambient air is 42-26 ug/m3, Particulate

matter (PM10) is 740-214 µg/m3 and Chromium is 7.12 - 4

ug/m3. , whereas the standard limits for these parameter in

the ambient air shall be less than 14ug/m3, 100µg/m3 and

0.5ug/m3 respectively. All these parameters are more than

permissible limit, so it is in hazardous area, which leads to

health issues to the workers/employers , hence we request

you to provide another safe area for the construction of

CETP.

H2S Level in the ambient air

mentioned by the bidder is very

high. Bidder has to reconfirm

whether sampling done in ambient

air or inside effluent tanks. Many

Tannery CETPs are functioning

without any issues. In any case

the existing CETP will not used

and project is going to be

implemented in the new location.

However Bidder is advised to get

ambient air quality from EIA

Consultant appointed by JTETA

and the selected contractor shall

have to make his own

arrangement for the EHS activity

at site.
