3. Due to the stringent Nuclear Regulatory Commission**("N~CH)** 

### reauirements for ·diesel generator readiness, NNECO has in the past. and may be ·required in· the future to perform scheduled testing of the emergency generators on days for which the Commissioner has forecast that ozone levels will be "moderate to u-n.neal chiul

# " 8.**~~ECO** has not yet performed approved Official U.S. Snvironmental Protection Agency (EPA) Reference Method 7 stack testing ("stack testing") on the eight (5) generators ("generators"'") subject .to Section**22a-17~-22** of the Regulations.**N~ECO** proposes to use assumed Bull Load Emission Rates ("FLERS") for the' purposes of calculating ERCs \1.''1til actual NOx emission rates are determined through stack testing.

9. 3ased on these assumed FLERs,**calculatio~s** show that NNECO was required to have thirty one and one tenth peak based ozone

season ERCs (31.1) on hand prior co the 1997 ozone season.

10. In September, 1997, pursuant to Section**22a-17~-22(j}** of the Regulations,**h~ECO** acquired an initial five tons of approved

ozone season ERCs a."ld ten tons of non-ozone season ERCs. In December of 1997,' NNECO purchased an additional eighty tons

ozone**seaso~** ERCs. NNECO intends to continue purchasing approved 

### ERCs as needed.

12. Aooroved ERCs are defined for the purpose of this order as those for which the Commissioner has Drovided written authorization for use in comoliance**~lth** Section**22a-17~-22** of the Regulations.

3. The Commissioner, in accordance with the provisions of this trading agreement and order, and pursuant to § 22a·274-22 (j) of the Regulations hereby allows NNECO to comply with § 22a-174-22 of the Regulations through use of ERC erading referenced in Section A, herein, to achieve the nitrogen**oX~de** emission reduction required by Section 22a-174-22 (a) (2) of the Regulations.
