Until May 1, 2007, before the first day of each month NP shall have in its

possession sufficient approved DERCs for the current day for the peaking unit

based on the following calculations;

Before the first day of each month, NP shall estimate DERCs required for such

month for the peaking unit as follows:

(i) At all times:

Estimated DERCs (in tons) use [«(FLER in lbslMMBtu) - (0.95 x NOx

allowable rate in IbslMMBtu)) x (estimated

fuel use in MMBtu)] .;. 2000 pounds/ton

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

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

Actual OERCs (in tons); [«(FLERin IbslMMBtu) - (0.95 x NOx allowable rate

in IbslMMBtu)) x (actual fuel use in MMBtu)] .,. 2000

pounds/ton

Where:

• NOx allowable rate = allowable limit rate in IbslMNlBtu shown in Table 1 of

this Trading Agreement and Order.

• FLER = full load emission rate in IbslMMBtu as shown in Table 1 of this

Trading Agreement and Order.

• Discount (0.95) ::; 5% design margin applied to the allowable limit rate.

ii) During the ozone season onlv:

No later than December 31st each year, NP shall acquire and permanently retire

seven ozone season DERCs for every actual ton of excess NOx emitted from the

peaking unit during the previous ozone season based upon the actual emissions for

each day that Connecticut one hour ozone levels were forecasted to be "moderate

to unhealthful", "unhealthful", or "very unhealthful", until such time that the EPA

revokes the I-hour standard. Upon such revocation, NP shall calculate and

permanently retire seven ozone season DERCs for every actual ton of excess NOx

emitted from the peaking unit during such ozone season based upon the actual

emissions for each day that Connecticut eight hour ozone levels were forecasted

to be "unheo.lthy for sensitive groups", "unhealthy", or "very unhealthy".

Where:

Actual ton of excess NOx emitted; [«(FLER in IbslMMBtu) - (0.95 x

NOx allowable rate in IbslMMBtu)) x (actual

fuel use in MMBtu)] .,. 2000 poundsltQn

The total actual tons of excess NOx emitted from the peaking unit during

forecasted ozone exceedance days shall be multiplied by seven and then rounded

to the next greater whole ton, to determine the number of DERCs to be

permanently retired. This requirement is in addition to the NP's requirement to

estimate excess emissions and subsequent permanent retirement of a sufficient

number of approved DERCs in accordance with paragraph C.2.a.(i) of this

Trading Agreement and Order.

2004, October I, 2005 and October I, 2006, NP shall estimate and acquire the

amount of DERCs or allowances required for such non-ozone season needed to

comply with Section 22a-174-22(e)(3) of the Regulations as follows:

Estimated DERCs (tons) use = [Estimated fuel use in M11Btu from October 1
