3Today’s Agenda Is this an Actual Emergency? Emissions Standards Now What?
4Emergency? TEXAS FEDERAL Unforeseen power or gas service failure, flood, fire, or life-threatening situationYESEmergency runtime limits (876 hrs per TX Permit)NO100 hours per year Maint. & Testing allowedSevere Storm Avoidance at Airports or NASAOther Storm Avoidance up to 30 minutes advanceNEW! Demand Response – up to 100 hrs/yr incl. M&TNEW! Peak Shaving - up to 50 hrs/yr incl. M&TNO?
5EPA Emergency Engine Regs – Current vs. Proposed TypeCurrentProposedDemand Response15 hours per year100 hours per yearNESHAP onlyNSPS and NESHAP will allowPeak ShavingNot allowedUp to 50 hours per year
6Proposed Demand Response Changes Up to 100 hours per year for non-emergency activitiesHours include Demand Response, Maint. & Testing, Peak Shaving HoursCan Get Paid – Peak Shaving up to 50 hrs/yearTCEQ requires PBR or Case-By-Case PermitFed Regs Aligned (NESHAP & NSPS)
7Proposed Changes - Details, Details Demand Response When:Regional Transmission Authority or equivalent balancing authority declares Energy Emergency Alert Level 2 (EEA Level 2)Voltage sag of 5% or more below standard voltage or frequency.Peak Shaving When:Done as part of program with local distribution system operators.Power can only be used at facility or towards the local system.Expires April 16, 2017
8Texas Requirements Permits By Rule (PBR) (Portable & Emergency Engines & Turbines)(Maintenance, Startup & Shutdown)(Stationary Engines & Turbines; Peak Shaving)Case-by-case (Peak Shaving)PBR = 876 hours emergency usePaperwork– review, keep copies, records of compliance, no fee or registration.– same as above if MSS project less than 180 days.
9DFW Minor Source NOx Rule All federal and state regulations plus:No Maintenance & Testing 6 am – noon, with few exceptionsOld Diesels Relocated into DFW must meet at least emergency engine emissions standardsNatural Gas-fired = 0.5 g/bhp-hr NOx, 0.6 for landfill gas
10Introduced much later than non-road regulations In 2006 EPA began to regulate engines in stationary applicationsKnown as New Source Performance Standards (NSPS)No “flexibility program” for OEM’s in NSPSFrom April 2006 Tier 1 standards were mandatedNo factory certification requiredFrom Jan 2007 NSPS harmonized regulatory limits & timing with EPA’s non-road regulationsengines ≤3000 bhp & <10 litre / cylinder must be certified to the non-road Tier limits for their specific model year & power outputengines >3000 bhp but <10 litre / cylinder must be certified to non-road Tier 1 limits for their specific maximum engine powerengines ≥10 litre / cylinder & <30 litre / cylinder must be certified to Marine Tier 2 limits for their specific displacement & maximum engine power2010+Alignment with non-road regulations continues for non-emergency engines
11Federal Requirements Diesel Natural Gas EPA Standards for Certified Emergency Diesel GensetsFor most engines >130 hpNOx: 2.0g/hp-hr (3.0g/hp-hr existing)CO: 4.0g/hp-hrVOC: 1.0g/hp-hrInstall, Configure per Mfg Hour meterInitial Emissions Performance Test Use ULSDRecord-keeping
13New Regulations Maintenance Change oil, filter every 500 hrs. or annually.Option to use oil analysis program to extend.Inspect air cleaner every 1,000 hrs. or annually.Inspect hoses, belts every 500 hrs. or annually, replace as needed.Records:malfunctions & reducing emissions during, performance tests, maintenance, monitoring results, hours ops., emergency notifications, demand response, peak shaving, non-emergency uses.
14Close, but no cigar! EPA taking public comments until July 23, 2012 Webinars – 6/20, 6/25, 6/28
