(a)Definitions. The following words and terms, when used in this section, have the following meanings, unless the context indicates otherwise:

Aggregator-A person that arranges for the sale of credits generated by another person, or arranges for the credits to be certified, verified and registered.

Agricultural operation-The management and use of farming resources for the production of crops, livestock or poultry, or for equine activity.

Baseline-

(i) The compliance activities and performance standards that must be implemented to meet current environmental laws and regulations related to the pollutant for which credits or offsets are generated.

(ii) The term includes allocations established under this chapter, in a TMDL or in a similar allocation, for the pollutant.

BMP-Best management practice-

(i) Schedules of activities, prohibitions of practices, maintenance procedures and other management practices to prevent or reduce pollutants to surface waters of this Commonwealth.

(ii) The term includes treatment requirements, operating procedures and practices to control plant site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw material storage.

(iii) The term includes activities, facilities, measures, planning or procedures used to minimize accelerated erosion and sedimentation and manage stormwater to protect, maintain, reclaim and restore the quality of waters and the existing and designated uses of waters within this Commonwealth before, during and after earth disturbance activities.

(iv) The term also includes riparian buffers, soil and slope stabilization measures, control of fertilization practices, and other actions and measures designed to reduce erosion and runoff of soil, sediment and pollutants from the land surface during precipitation events; or to reduce the contamination of groundwater with pollutants that may affect surface waters.

(v) The term includes BMP measures developed under this title to reduce pollutant loading to surface waters.

Certification-Written approval by the Department of a proposed pollutant reduction activity to generate credits before the credits are verified and registered to be used to comply with NPDES permit effluent limitations.

Credit-The tradable unit of compliance that corresponds with a unit of reduction of a pollutant as recognized by the Department which, when certified, verified and registered, may be used to comply with NPDES permit effluent limitations.

Credit reserve-Credits set aside by the Department to address pollutant reduction failures and uncertainty.

DMR-Discharge monitoring report-The Department or EPA supplied forms for reporting of self-monitoring results by the permittee.

Delivery ratio-A ratio that compensates for the natural attenuation of a pollutant as it travels in water before it reaches a defined compliance point.

Edge of segment ratio-A ratio that identifies the amount of a pollutant expected to reach the surface waters at the boundary of a Chesapeake Bay Watershed Model segment through surface runoff and groundwater flows from a pollutant source within a watershed segment.

Nutrient-Nitrogen or phosphorus.

Offset-The pollutant load reduction measured in pounds that is created by an action, activity or technology which when approved by the Department may be used to comply with NPDES permit effluent limitations, conditions and stipulations under Chapter 92a (relating to National Pollutant Discharge Elimination System permitting, monitoring and compliance). The offset may only be used by the NPDES permittee that the Department determines is associated with the load reduction achieved by the action, activity or technology.

Pollutant-Nutrient or sediment.

Pollutant reduction activity-An activity, such as a BMP or effluent control, that is implemented to prevent or reduce a pollutant load to surface waters of this Commonwealth.

Registration-An accounting mechanism used by the Department to track certified and verified credits before they may be used to comply with NPDES permit effluent limitations.

Reserve ratio-A 10% ratio that is applied to the pollutant reductions generated, which establishes the credits to be set aside for the Department's credit reserve.

Threshold-Activities and performance standards beyond baseline compliance which are required under subsection (d)(3) before credits may be certified.

Tradable load-The amount of nonpoint source pollutant reduction determined to be the projected future pollutant load that is the difference between the total reduction theoretically possible from maximum implementation of pollutant reduction activities, and the reduction associated with a level of pollutant reduction activities identified by the Department as reasonably attainable.

Trade-A transaction that involves the sale or other exchange, through a contractual agreement, of credits that have been certified, verified and registered.

Trading ratio-A ratio applied to adjust a pollutant reduction when calculating credits for a pollutant reduction activity. A trading ratio is used to address uncertainty, water quality, reduction failures or other considerations. The term will include a delivery ratio, an edge of segment ratio and a reserve ratio.

(d)Eligibility requirements for the Chesapeake Bay.

(1)General. To generate credits or offsets, the person shall demonstrate a reduction in the pollutant load beyond the pollutant load allowed under applicable baseline requirements, and beyond any applicable threshold.

(2)Baseline requirements to generate credits.

(i) For a nonpoint source, the baseline is the set of requirements in regulations applicable to the source at the location where the credits or offsets are generated, and the pollutant load associated with that location as of January 1, 2005. If since that date new requirements or operation changes have occurred that necessitate a revised set of requirements those establish the baseline. For an agricultural operation, baseline includes compliance with the erosion and sedimentation requirements for agricultural operations in Chapter 102 (relating to erosion and sediment control), the requirements for agricultural operations under § 91.36 (relating to pollution control and prevention at agricultural operations), § 92a.29 (relating to CAFO) and the requirements for agricultural operations under Chapter 83, Subchapter D (relating to nutrient management), as applicable.

(ii) For a point source, the baseline is the pollutant effluent load associated with effluent limitations contained in the NPDES permit based on the applicable technology based requirements, or the load in a TMDL or similar allocation, whichever is more stringent.

(3)Threshold requirements to generate credits.

(i) To generate credits, an agricultural operation must meet one of the following threshold requirements at the location where the credits are generated.

(A) Manure is not mechanically applied within 100 feet of a perennial or intermittent stream with a defined bed or bank, a lake or a pond. This threshold can be met through one of the following:

(I) There is not a perennial or intermittent stream with a defined bed or bank, a lake or a pond on or within 100 feet of the agricultural operation.

(II) The agricultural operation does not mechanically apply manure, and applies commercial fertilizer at or below agronomic rates contained in the current Penn State University Agronomy Guide published by Pennsylvania State University.

(B) A minimum of 35 feet of permanent vegetation is established and maintained between the field and any perennial or intermittent stream with a defined bed or bank, a lake or a pond. The area may be grazed or cropped under a specific management plan provided that permanent vegetation is maintained at all times and there is no mechanical application of manure within the buffer area.

(C) The applicant applies an adjustment of at least 20% to the overall amount of the pollutant reduction generated by the pollutant reduction activity the person is submitting for certification.

(ii) The Department may establish other threshold requirements necessary to ensure the effectiveness of the use of credits to meet legal requirements for restoration, protection and maintenance of the water quality of the Chesapeake Bay.

(4)Compliance status. A person who by past or current noncompliance has demonstrated a lack of ability or intention to comply with any of the following is not eligible for certification or offset approval or to use credits or offsets to meet permit effluent limits:

(i) A Department regulation, permit, schedule of compliance, order or certification.

(ii) A law or regulation that addresses pollution of waters of this Commonwealth.

(iii) A contract for the exchange of credits.

(5)Other requirements. The Department may establish other eligibility requirements to ensure the effectiveness of the use of credits and offsets to meet legal requirements for restoration, protection and maintenance of the water quality of the Chesapeake Bay.

(6)Failure to meet eligibility requirements. If at any time prior to registration of a credit the Department determines that a person no longer meets the eligibility requirements under this section, the Department may take appropriate action, such as prohibiting the person from participating in any trading under this section or denying a request for certification, registration of any credits or approval of offsets.

(e)Certification requirements for the Chesapeake Bay.

(1)General. A pollutant reduction activity must be certified by the Department for the generation of credits before the credits may be applied to meet permit effluent limitations. Certification will serve as the Department's final determination of the amount of credits that the pollutant reduction activity may generate. A permittee may only use credits to meet permit effluent limits if certification is followed by verification and registration of the credits.

(2)Request for certification. A person who wishes to have a pollutant reduction activity certified by the Department to generate credits shall submit a written request for certification in the format required by the Department.

(i) The request for certification must contain information sufficient to demonstrate the following:

(A) That the location where the pollutant reduction activity will be implemented will meet applicable eligibility requirements under subsection (d) and will continue to meet those requirements throughout the applicable term of the certification.

(B) That the pollutant reduction activity will meet acceptable standards for construction and performance, including operation and maintenance, throughout the applicable term of the certification.

(C) That the calculation requirements of this section have been met.

(D) That the implementation of the pollutant reduction activity will be verified as described in a verification plan that meets the requirements of paragraph (5).

The Department will not register credits if the person who generates the credits has not implemented, or demonstrates a lack of ability or intention to implement, operations and maintenance requirements contained in the certification, verification plan, or other requirements of this section. The Department will not register credits submitted by an aggregator that is currently not complying, or demonstrates a lack of ability or intention to comply, with this section.

(h)Use of credits and offsets to meet NPDES permit requirements related to the Chesapeake Bay.

(1) A permittee will only be authorized to use credits and offsets through the provisions of its NPDES permit. The permit conditions will require appropriate terms, such as recordkeeping, monitoring and tracking, and reporting in DMRs.

(2) Only credits and offsets generated from activities located within the Chesapeake Bay Watershed may be used to meet NPDES permit requirements related to the Chesapeake Bay. Credits generated in either the Susquehanna or Potomac basins may only be used in the basin in which they were generated, unless otherwise approved by the Department.

(3) A permittee shall ensure that the credits and offsets that the permittee applies to its permit for compliance purposes are certified, verified and registered, or approved, under this section for the compliance period in which they are used.

(4) The Department may authorize a period of 60 days or less following the completion of the annual compliance period in an NPDES permit, for a permittee to come into compliance through the application of credits and offsets to the permit provided that the credits were registered and offsets were approved for use during that compliance period.

(5) A permittee relying on credits to demonstrate compliance with its permit effluent limitations, conditions and stipulations under Chapter 92a shall attain and maintain compliance with its permit. A permittee is responsible for enforcing the terms of its trade contract, when needed to ensure compliance with its permit. The Department may waive this requirement where the pollutant reduction activity fails due to uncontrollable or unforeseeable circumstances such as extreme weather conditions, and timely notice is provided to the Department, if the following apply:

(i) The failure is not due to negligence or willfulness on the part of the permittee.

(ii) The Department determines that replacement credits will be available.

(iii) The Department determines that the requirements for restoration, protection and maintenance of the water quality of the Chesapeake Bay will be met due to the requirements of this section, which may include the type of methodologies used when certifying credits, the existence of an approved legal mechanism that is enforceable by the Department, and the use of a credit reserve.

(6) A permittee shall document the use of credits and offsets in DMR forms, which the permittee shall submit at the end of each compliance year or as otherwise provided or required in the permit. Credits and offsets shall only be used to meet permit effluent limits for the compliance period for which they are certified, verified and registered, or approved, by the Department under this section.

(i)Water quality and TMDLs.

(1) Use of credits and offsets under this section will be allowed only where surface water quality will be protected and maintained as required by applicable regulations, including this chapter, Chapters 92a and 93, as well as Department permits, schedules of compliance and orders.

(2) Use of credits and offsets under this section must ensure that there is no net increase in discharge of pollutants to the compliance point used for purposes of determining compliance with the water quality standards established by the states of Maryland and Virginia for restoration, protection and maintenance of water quality of the Chesapeake Bay.

(3) Where a TMDL has been established for the watershed where the permitted activity is located, the use of credits and offsets under this section will be consistent with the assumptions and requirements upon which the TMDL is based.

(4) Use of credits and offsets under this section will comply with the antidegradation requirements contained in Department regulations.

(j)Public participation. The Department will publish a notice in the Pennsylvania Bulletin of the receipt of administratively complete requests for certifications of a pollutant reduction activity to generate credits. The notice will provide an opportunity for informal comments. This notice is not required to follow the requirements of § 92a.82 (relating to public notice of permit applications and draft permits). The Department will also publish notice in the Pennsylvania Bulletin of its final certification determination.

(k)Use of credits and offsets generally. Nothing in this section precludes the Department from allowing the use of credits and offsets to be used to meet permit limits other than those established for restoration, protection and maintenance related to the water quality of the Chesapeake Bay.
