At all times:

Before the first day of each month, PSEG calculate projected worst case DERCs required

for that calendar month as follows:

Estimated DERCs (tons) ={[estimated worst case NOx emission rate in IbslMMBtu -

((0.95) x (NOx allowable emission limit or proportioned emission rate calculated

pursuant to Section 22a-174-22(f)(2)(A) of the Regulations in IbslMMBtu))] x

No later than the twentieth day of each month, PSEG shall calculate and permanently

retire DERCs used in the preceding calendar month, as follows:

rate* is less than the baseline emission rate or greater than the NOx allowable

emission limit.

(ii) When the boiler has a daily NOx emission rate (24-hour average) exceeding the NOx

allowable emission limit, calculate the amount of DERCs used, as follows:

Actual DERCs (tons) = {[(CEM-recorded NOx daily average emission rate in

IbsIMMBtu*) - ((0.95) x (NOx allowable emission limit or

proportioned emission rate

limit ofO.15Ibs/MMBtu. Prior to October I, 2006, 2007 and 200S, PSEG shall

estimate and acquire the amount of DERCs or allowances required for such nonozone season needed to comply with Section 22a-174-22(e)(3) of the Regulations

as follows:

Estimated DERCs (tons) = [Estimated fuel use in MMBtu from October I through April

30 x (lower of the estimated seasonal average NOx emission

rate or the proportioned 24-hour allowable emission limit in

Ibs/MMBtu during October I through April 30) - (0.95 x 0.15

Ibs/MMBtu)] .;. 2000 pounds/ton.

No later than May 31, 2007, 200S and 2009, in addition to the DERCs retired in

paragraph e.7.a., calculate and permanently retire DERCs used in the preceding nonozone season as follows:

Actual DERCs (tons) = [Actual fuel use in MMBtu from October I through April 30 x

(lower of the actual seasonal average NOx emission rate or the

proportioned 24-hour allowable emission limit in Ibs/MMBtu

during October I through April 30) - (0.95 x 0.15 Ibs/MMBtu)] .;.

2000 pounds/ton.

3. Delete paragraph e.S. and substitute the following therefore:

the excess emissions plus a 100% premium within sixty (60) days of PSEG's discovery of

the DERC shortfall. PSEG shall certify and report any such DERC retirement to the

Commissioner in accordance with paragraph C.28. of this Trading Agreement and Order.

4. Delete paragraph C.12 and substitute the following therfor:
