Activity: Hilcorp applied for a minor permit under 18 AAC 50.502(c)(3) for an increase in NOx emissions. The application is also classified under 18 AAC 50.508(5) for an owner requested limit (ORL) which includes the removal of the well test flare EU 16 to avoid a PSD major classification for NOx. The application is also classified under 18 AAC 50.508(6) to rescind the existing ORLs at the stationary source which include hourly limits on the gas-fired turbines EUs 1 and 2 and the standby compressor engines EUs 43 and 44. The Permittee also requested to re-calculate potential to emit (PTE) for the emergency generator EU 6 using 500 hours per year as allowed by the September 6, 1995 EPA Seitz Memo.
