develop national programs or standards for these devices in the future . 6353

44 Fireplaces V.A contributions to air quality, endangerment of public health and welfare, emissions, potential emission reductions, costs, prices, and sales of fireplaces . We request data that might help us potentially develop new or revised national programs or a source category listing and standards under section 111(b) for these devices in the future. We are especiall y interested in data on current and projected sales of new woodburning fireplaces versus gas - fired fireplaces, current and projected usage patter ns for new fireplaces versus existing fireplaces, current and projected quantities of wood burned per existing and new fireplaces, current and projected best s ystems of 6353emission reduction for new fireplaces versus existing fireplaces and costs of current and projected best systems versus current costs of fireplaces. Also, we are interested in national data and how these data vary by state and local areas. 45 Determination of Best Systems of Emi ssion Red

uction [BSER] and Prop osed Emission Leve l s V.B anal ys e s on which we base the proposed standards. Moreover, the EPA invites specific comments that provide additional data and anal ys e s that would support a different standard. Interested persons should note that the EPA will consider promulgating a more s tringent or less stringent standard than what we are proposing for any of these categories, if the record contains data or anal ys e s that support a different standard . 6354

46 Cord Wood L evel in AAA V.B.1.a emission test data using cord wood to help us determine if the proposed emission levels should be adjusted for any differences between crib wood and cord wood [for adjustable burn rate stoves]. 6355 , 6356 47 Backsliding for Cataly tic Stoves V.B.1.a whether we should maintain a separate, lower limit f or catal ytic heater models for the proposed Step 1 emission limits, based on the current s tate of Washington catal ytic standard of 2.5 g/hr. 6356 48 Three - Step Approach for AAA V.B.1.b whether we should allow a longer approach that is implemented in 3 steps over 8 ye ars instead of the preferred approach of 2 steps over 5 years. 6357 49 Single Burn Rate Stove Research and Development V.B.1.c emissions and R&D assumptions. 6357 50 Two - Step Approach in QQQQ for HH V.B.2.a on this determination that this approach is reasonable and the degree to which other options would be appropriat e. 6359 51 Cord Wood L evel in QQQQ for HH V.B.2.a emission test data using cord wood and different te st methods to help us determine if the proposed emission levels should be adjusted for any differences in test methods and test fuels, e.g., crib wood and cord wood [for hydronic heaters]. 6359 52 Three - Step Approach for HH V.B.2.a whether we should allow a longer approach that is implemented in 3 steps over 8 ye ars instead of the preferred approach of 2 steps over 5 years. 6360 53 Emission Levels and Compliance Deadlines for Forced - air Furnaces V.B.2.b the proposed emission levels and compliance deadlines, as well as the environmental impacts and market implications for setting emission limits that match what we are proposing for hydronic heaters. 6361 5 4 Three - Step Approach for V.B.2.b whether we should allow a longer approach that is implemented in 3 steps over 8 ye ars instead of the preferred approach of 2 steps over 5 years. 6361Forced - Air Furnaces

5 5 Format of Standard for Masonry

Heaters V.B. 3 .c whether a g/kg format would be better than lbs/million BTU heat output 6361 56 Level of Standard for Masonry

Heaters V.B. 3 .c proposed BSER and whether there are additional alternatives. For example, if we

were to develop a g/hr average format in addition to the lb/MMBtu heat output format, are there products that might meet a dail y average over the heating period versus the averaging only over the combustion period, and if so, how would this affect levels of performance and impacts on the environment? 6362

57 Compliance Deadline for Masonry Heaters V.B. 3 .c the degree to which the dates could be sooner. 6362 58 Alternative Approach V.B.4 whether the final rule should be our (preferred) proposed two - step approach or whether the final rule should be this alternative three - step approach. We do not intend for the final rule to allow a choice between the two approaches. 6362 59 Compliance Extension f

or Small Volume Masonry Heater Manufacturers V.B.4 w e did not develop a three - step approach for masonry heaters under subpart RRRR, since it is a one - emission - level standard, but we are seeking comments on our proposed 5 - ye ar compliance extension for small volume masonry heater manufacturers . 6362

60 Alternative Approach V.B.4 potential justifications for implementing a three - step standard, instead of our proposed two - step standard for each of the appliances affected by this proposed rule , to provide additional flexibility for manufacturers that have different capabilities and resources to ultimately reach the most stringent BSER. 6362 61 Alternative Approach -- Step 2 V.B.4 data and potential environmental and economic justifications, on whether the described A lternative Approach Step 2 emission limits represent BSER within 3 ye ars of the effective date of the final rule. We also seek comment on whether an additional 5 years would be necessary to transition from the A lternative Approach Step 2 to the A lternative Approach Step 3 limit, or whether such a transition could be made in a shorter time period 6363

62 Alternative Approach

– Step 1 V.B.4 whether the alternative Step 1 limit should become effective upon the effective date of the final rule or after a 1 - ye ar “adjustment” period [ for single burn rate wood heaters and forced - air furnaces ]. 6363 63 Alternative V.B.4 balanc ing industry ’s R&D needs with timely and efficient standards . 6363Approach

64 Efficiency V.B.5 .a supporting data that would help inform the need for and level of a possible efficiency standard . Also, we ask for specific comments on how, in the meantime, to best ensure consumers have access to the best information on efficiency performance, e.g. , labels, owner’s manual, Burn Wise website and/or other means . 6363 65 Carbon Monoxide (CO) Standards V.B.5.b supporting data on the need for and level of a possible CO emissions standard. 6363 66 CO Monitors V.B.5.b whether we should require CO monitor s to help ensure proper operation of the heater and to reduce health and safety concerns for appliances that are installed in occupied areas 6363 67 Pellet Fuel Requirements V.B.5.c decision that the Pellet Fuel Institute (PFI) program is a good program that obviates the need for the EPA to develop our own program at this time. We ask for specific comments on this decision and the details of the PFI program. 6364 68 Proper Operation V.B.5.d whether we should include more specific requirements on proper operations, such as the moisture content of the wood and visible emission limit s. 6364 69 Compliance Deadlines V.C whether we should have a cap on the total units sold in the 5 years, perhaps 50 units [for small - volume maso nry heater manufacturers]. 6365 70 Compliance Deadlines V.C the need for either a compliance date extension or a compliance date exemption for masonry heaters and the length of time that we should allow . 6365 71 Compliance Deadlines V.C the need for a compliance date extension fo r small volume manufacturers of adjustable burn rate stoves, pellet stoves, or single burn rate stoves. 6365 72 Compliance Deadlines V.C the need for a compliance date extension fo r small volume manufacturers of hydronic heaters or forced air furnaces, and if so, what number of appliances sold would constitute a small volume manufacturer. 6365 73 Compliance Deadlines V.C need for logjam provisions in case ISO - accredited laboratories and IS O - accredited certifying bodies and EPA cannot process the large number of certification applications in a timely

manner. 6366 74 Compliance Deadlines V.C whether these compliance timelines strike the right balance between avoiding undue economic burdens and the need to get better performing models on the market as soon as possible to reduce emissions, and whether other compliance dates would be appropriate . 6366 75 Streamlining V.D The “k” list of design changes and tolerances which are presumed to affect emissions and thus trigger a new certification test. 636676 Streamlining V.D exact event(s) that should be used as the trigger(s) to retest and whether the triggering event(s) should vary by appliance type. 6366 77 Test Methods V.E all test method related issues and any data supporting such issues or concern s. 6367 78 Administrative Requirements V.F replac ing the current subpart AAA hearing and appeal procedures with a streamlined Petition for Review process and also us ing this process in subparts QQQQ and RRRR. [ This process would allow accredited laboratories and manufacturers to contest audit test findings, laboratory accreditations, certification denials, and certification revocations b y submitting a written request and supporting documentation to the EPA. This process would allow for expedited review and resolution. ] We request specific comments on this proposed process and other ways to improve or streamline procedures while preserving the integrity of the program . 6367
