### Description

Table 10

- 4 in Chapter 10 (at p. 10

- 13) and Table 22 in Appendix D (at p.42) of the revised SIP

are identical tables, entitled “ 2001

- 2003 Average Visibility Improvement for 4 SCR, 4 SNCR and

2 SNCR/2 Shutdown Scenarios .” In the June 27, 2013 public review drafts of those documents

,

these tables were incorrect because they actually contained visibility data for a single year, 2003

,

rather than for the 2001

- 200 3 period. Accordingly, the 4 th 

### graph in Figure 11 on p. 41 of

Appendix D is also incorrect. (A corrected version of Figure 11 appears in the written testimony

of Gi

- Dong Kim, NMED Ex. 12)

This same error is also reflected in the text at p. 37 of Appendix D, in the last sentence. The

sentence should state that the largest average differences in visibility improvement from the 4

SCR and the 2 SNCR/2 shutdown scenarios are 0.47 dv ( rather than 0.28 dv ) at Mesa Verde and

0.24 dv ( rather than 0.16 dv ) at Cany onlands. This same textual error is replicated in paragraph

6 of the BART determination at p. 10

- 15 of Chapter 10 and p. 45 of Appendix D.

Finally, there is a transcription error that appears in Tables 16

– 19 on pp. 25

- 28 of Appendix D

. On each table, the NOx emission rate for the baseline scenario shou ld be 0.33 lbs/MMBtu, not

0.30. The error is only in the table, not in the underlying modeling. That is, the inputs to

Calpuff were correct; they were merely transcribed incorrectly into the table.
