New Source Reform 

Agenda 

10.00 to 12:00 and 1:00 to 2:00 Sept. 4, 1996 

EPA Region 6 

,a/W

Participants: TNRCC: Victoria Hsu, Dale Beebe-Farrow 

EPA Region 6: Jole Luehrs, Stanley Spruiell, Mary Stanton 

New Source Reform Program Discussion, Clarification and Comparisons 

Clean Units/Facilities and SB 1126 \ .——-

Disparity in allowables and actuals \ 

Hourly vs. annual PTE \ 

No check on actual increases (SIP strategy) \ \ . - -

NSPS capital cost test for reconstruction

 f r 

Clean facilites allow replacement in kind '• 

Emission trades not allowed with clean facilites 

Case by Case determination requires public notice, good for 5yrs 

Pollution Control Projects and Standard Permits 

• 5 yr monitoring requirement 

• Need Pollution Prevention definition of Environmentally Beneficial Test 

PALs and Flexible Permits 

Can flexible permit cap be used to establish a plantwide applicability limit? 

New sources and amendments vs. NSR applicability 

Partial or plantwide cap 

When a modification is triggered, is NSR applied to just that project? 

Public Notice 

NNSR EPA and NNSR Texas 

Netting for Small Major Sources (retroactive reviews or netting for all projects) 

Netting for Large Major Sources (tagged window, 5tpy de minimis) 

Internal Offsets 

Netting baseline change to highest 12 month utilization in last 10 yrs 

Netting witiiin the project 

Will collateral increases be included as project increases? 

Upcoming Activities: 

• EPA headquarters (Sept 16-18) Hearing, Subcommittee meeting, TX issues meeting 

Agency comments due to EPA (Oct. 21, 1996)

No alternative allowed 

Utilization level x Current allowable 

emission rate factor (incl all emission limits 

eg BACT, MACT, NSPS, RACT etc.) 

Project increase must be > or = sig. level 

Project net increase > 0 triggers netting. 

Defined as creditable increases and 

decreases at the source from time of project 

application to SOO 

TNRCC Current Practice 

2 yr period prior to change using ave. actual 

Administrator discretion for a more 

representative time frame 

2 yr or representative period noted above 

based on actual emissions at the time 

Same as EPA 

For VOC look at increases only > 5tpy 

Project decreases are not included 

5 tpy trigger also in effect in Moderate NA 

counties 

For NOx 40 tpy netting tr'ggor in effect 

under the temporary NO. exemption 

Comments 

May want to 

consider assessing 

the change for 

increases by 

potential to potential 

and decreases actual 

to poten.ial actual 

Tagged window for 

the >250tpy PTE 

will account for al! 

trivial increases, 

once netting is 

triggered. 

Moving windows 

may need to review 

increases at some 

specific interval or 

require netting with 

each increase.

TNRCC Current Practice 

182(f) exemption is permanent in El Paso 

and DFW and expires Dec 31, 1997 in HG 

and BPA assuming EPA grants extension 

For 1) Pb, CO, PMI0; 2) VOC site <250 tpy 

PTE 3) VOC site > 250 tpy PTE if Start of 

construction (SOC) before 11/15/97: period 

is 5 yrs prior to SOC and tliru SOO 

For VOC site > 250 tpy PTE, if SOC after 

11/15/97 period from 11/15/92 thru SOO . 

For 1) NOX site >250 tpy PTE 2) NOX site 

with <250 tpy PTE if SOC before 11/15/97 

period is 11/15/92 thru SOO 

For NOX site <250tpy PTE if SCC after 

11/15/97: period is 5 yrs prior to SCC thru 

SOO
