Environmental Laboratory Accreditation

[46 Pa.B. 5088]
[Saturday, August 20, 2016]

 The Environmental Quality Board (Board) proposes to amend Chapter 252 (relating to environmental laboratory accreditation). This proposed rulemaking clarifies existing requirements, deletes or amends overly restrictive and cost prohibitive requirements, and proposes additional requirements necessary for laboratory accreditation. This proposed rulemaking also amends the fee structure in § 252.204 (relating to fees).

 This proposed rulemaking was adopted by the Board at its meeting of May 17, 2016.

A. Effective Date

 This proposed rulemaking will go into effect upon final-form publication in the Pennsylvania Bulletin.

B. Contact Persons

 For further information contact Aaren S. Alger, Chief, Laboratory Accreditation Program, P.O. Box 1467, Harrisburg, PA 17105-1467, [phone]; or William S. Cumings, Jr., Assistant Counsel, Bureau of Regulatory Counsel, P.O. Box 8464, Rachel Carson State Office Building, Harrisburg, PA 17105-8464, [phone]. Persons with a disability may use the Pennsylvania AT&T Relay Service at [phone] (TDD users) or [phone] (voice users). This proposed rulemaking is available on the Department of Environmental Protection's (Department) web site at www.dep.pa.gov (select ''Public Participation,'' then ''Environmental Quality Board (EQB)'').

C. Statutory Authority

 This proposed rulemaking is being made under the authority of 27 Pa.C.S. §§ 4103(a), 4104 and 4105 (relating to establishment of program; powers and duties; and powers and duties of Environmental Quality Board) and section 1920-A of The Administrative Code of 1929 (71 P.S. § 510-20), authorizing and directing the Board to adopt regulations necessary for the proper performance of the work of the Department.

D. Background and Purpose

 Chapter 252 became effective on January 28, 2006, and was amended on April 10, 2010. While completing ongoing rounds of laboratory assessments under Chapter 252, the Laboratory Accreditation Program (Program) discovered various provisions that are unclear, the regulations are lacking sufficient detail to ensure full compliance with the regulatory requirements or standards are overly restrictive and cost prohibitive. The Program also determined that several necessary standards for accreditation are lacking. The scope of Chapter 252 remains unchanged.

 Under 27 Pa.C.S. § 4104(6), the accreditation fees must be ''in an amount sufficient to pay the department's cost of implementing and administering the accreditation program.'' In addition, § 252.204(b) requires the Department to recommend to the Board regulatory changes to the accreditation fees every 3 years to address any disparity between Program income generated by the fees and Program costs. In accordance with this requirement, the Program performed a workload analysis to evaluate the costs associated with the Program. Based on this workload analysis, the Department determined that the accreditation fees in § 252.204 are not sufficient to recover the Department's costs to implement the Program. This proposed rulemaking provides a new fee structure to cover the costs of the Program.

 The Department worked with the Laboratory Accreditation Advisory Committee (LAAC) to propose amendments to Chapter 252 in a manner that ensures appropriate requirements for environmental laboratory accreditation. The Department, with the assistance of the LAAC, ensured that the interests, concerns and needs of the regulated community were considered and implemented appropriately. The LAAC met throughout 2014 and 2015 to review and comment on drafts of the proposed Chapter 252 amendments presented by the Department. On December 2, 2015, the LAAC unanimously voted to recommend the proposed Chapter 252 amendments for presentation to the Board.

E. Summary of Regulatory Requirements

 Federal regulations exist for the certification of the analysis of drinking water samples but Federal regulations do not exist for the accreditation of the analysis of nonpotable water (wastewater) or solid and chemical materials. This proposed rulemaking is more stringent than the Federal requirements for laboratory accreditation but not more stringent than the current environmental laboratory accreditation regulations. This proposed rulemaking does not expand the Department's oversight or regulatory authority over environmental testing laboratories.

 Federal regulations cover the testing and analysis of samples from public drinking water suppliers. The Federal drinking water laboratory certification program consists of requiring the use of Federally promulgated methods for testing and analysis and recommended laboratory practices. Some of the requirements in these regulations are more stringent than the Federal standards for the certification of environmental laboratories performing testing or analysis on samples from public drinking water suppliers because the Federal standards offer recommendations or guidance that are mandated in Chapter 252.

 There are no Federal standards or regulations for accreditation of environmental laboratory testing for nonpotable water (wastewater) and solid and chemical materials. The Federal regulations do mandate specific test methods and performance of the testing laboratories, but do not mandate that the laboratories seek and obtain accreditation. Because there is no Federally mandated accreditation program for environmental laboratories testing nonpotable water (wastewater) and solid and chemical materials and the Federal certification program for testing of potable water consists mostly of recommended practices, most of these regulations are more stringent than the Federal program. This proposed rulemaking contains the minimum requirements for an environmental laboratory performing testing or analysis on wastewater and solid and chemical materials as well as drinking water.

 An effective laboratory accreditation program is a proactive measure to protect the public health and the environment and to help ensure that the results used to make critical decisions about the public health and environment obtained using Department and United States Environmental Protection Agency (EPA) approved procedures and that the data are of known and documented quality. In recent years, the Program has observed an increase in the number and severity of violations committed by commercial environmental labora-tories. These violations directly impact the quality of the data used for compliance decisions in the Commonwealth. The Program continues to investigate, enforce and penalize these noncompliant laboratories based on 27 Pa.C.S. Chapter 41 (relating to environmental laboratory accreditation) and its regulations. Nonregulation would result in a system that does not ensure the procedures that produce the overwhelming majority of data used for environmental decisions in the Commonwealth are being performed accurately. Without periodic in-depth onsite and offsite laboratory assessments, the Department cannot have confidence in the data submitted.

Subchapter A. General Provisions

 Sections 252.1 and 252.5 (relating to definitions; and NELAP equivalency) are proposed to be amended to correctly state that the Department offers and grants National Environmental Laboratory Accreditation Program (NELAP) accreditation.

 Laboratories reporting analytical testing results for any of the 12 statutes referenced in § 252.4(a) (relating to general requirements) are proposed to be included among the types of laboratories which fall within the scope of Chapter 252. Currently, only laboratories which test or analyze environmental samples fall within the scope of Chapter 252.

 The proposed rulemaking includes specific requirements for laboratories regarding development and maintenance of instructions for sample collection, preservation and sample receipt. To ensure that laboratories generating compliance data for the Department meet the same standards of performance, the requirement of NELAP laboratories to adhere to §§ 252.307 and 252.401 (relating to methodology; and basic requirements) is proposed to be added to § 252.5. The term ''onsite'' with respect to onsite assessments is proposed to be deleted throughout Chapter 252, with the exception for requiring onsite assessments for initial accreditation, to allow for the Department to explore cost-saving alternatives such as offsite assessments.

 Section 252.6 (relating to accreditation-by-rule) is proposed to be amended to specify that all laboratories performing testing or analysis for compliance testing or reporting results of compliance testing shall meet the requirements of this section and that laboratories are deemed to be accreditation-by-rule if, among other things, they only report the accredited-action-rule parameters in subsections (c) and (f).

Subchapter B. Application, fees and supporting documents

 Sections 252.201(a) and 252.203(a) (relating to application and supporting documents; and accreditation renewal) are proposed to be amended by deleting ''in writing'' and adding ''in the format specified by the Department'' to allow for advances in technology and submission of electronic applications.

 Section 252.203(d) is proposed to be added to require laboratories to provide notification to each affected customer of an expiration of the certificate of accreditation within 48 hours of the expiration.

 Section 252.204(a) is proposed to be amended to allow applicant laboratories to pay the accreditation fees by credit card when the Department can accept credit card payments. Laboratories choosing to pay by credit card will be required to pay all service charges or administrative fees in addition to the accreditation fees established by this section.

 An environmental laboratory will pay an initial application fee and annual renewal fees based on the appropriate accreditation categories sought. Under 27 Pa.C.S. Chapter 41, the fees provided in § 252.204 must be sufficient to pay the Department's cost of implementing and administering the Program, including processing applications for certificates of accreditation, the issuance, renewal, modification or other action relating to the certificate. Laboratories pay fees based on the number and complexity of the categories for which they request accreditation. The cost of each fee category is based on the number of assessor hours necessary to accredit an environmental laboratory for that given category.

 To appropriately distribute the cost of the implementation of the Program, the fee structure in § 252.204 is proposed to be amended to reflect the costs associated with implementation of the Program.

 Section 252.205(a)(2)(i) (relating to out-of-State laboratories) is proposed to be amended to add clarification that laboratories seeking secondary NELAP accreditation shall meet the requirements of § 252.5.

 In § 252.206 (relating to out-of-State onsite reimbursement), the rate for reimbursement of out-of-State travel for assessors is proposed to be changed from $50 to $75 per hour.

Subchapter C. General standards for accreditation

 Section 252.301(h) (relating to laboratory supervisor) is proposed to be amended to specify that the laboratory shall designate a Department-approved temporary laboratory supervisor if the primary laboratory supervisor is absent. The number of days that a laboratory supervisor may be absent is proposed to be amended from 16 days to 21 days.

 Terminology is proposed to be added to § 252.302(a) and (b) (relating to qualifications of the laboratory supervisor) to better explain the current requirements for laboratory supervisors at laboratories accredited to perform organics, trace metals and inorganic nonmetals analyses. The education and experience requirements for organics and trace metals analyses remains unchanged while the experience requirements for laboratory supervisors supervising inorganic nonmetals, basic microbiology, basic drinking water, basic nonpotable water and supervisors approved through the operator certification program are proposed to be reduced from 2 years to 1 year.

 Section 252.302(c) is proposed to be amended to explain that the requirements for a laboratory supervisor of an environmental laboratory performing microbiological testing require a minimum of 4 microbiology credits. The analysis of E. coli is proposed to be added to subsection (d) as one of the testing types allowed to be supervised by an individual meeting the less stringent laboratory supervisor requirements for ''basic'' microbiology. The ''basic'' microbiology laboratory supervisor's experience requirements in subsection (d) is proposed to be reduced from 2 years to 1 year.

 The educational requirements for laboratory supervisors of laboratories performing radiochemical analyses in § 252.302(e) is proposed to be changed to include credits in health physics instead of limiting the educational credits to chemistry.

 The operator certification exam for laboratory supervisors became available in July 2015. Therefore, § 252.302(h) allowing 2 years of testing experience to substitute for the laboratory supervisor subclassification for operator certification is no longer applicable and is proposed to be deleted and replaced with a minimum requirement of 1 year of analytical testing experience.

 Section 252.302(j) is proposed to be added to include experience and education requirements for whole effluent toxicity testing, which was previously included in the microbiology supervisor qualifications.

 Section 252.302(k) is proposed to be added to clarify that all college-semester credit hours shall be obtained from an accredited college or university and subsection (l) is proposed to be added to state that all foreign transcripts must be translated into English and evaluated for United States semester credit hour equivalency to ensure that all laboratory supervisors meet the same educational requirements.

 The EPA granted the Department primacy for the certification of cryptosporidium in 2014. The EPA mandates specific experience requirements for analysts performing testing of cryptosporidium that are not listed in Chapter 252. Accordingly, § 252.302(m) is proposed to be added to specify that if any method, regulation or program requires more stringent qualifications than those listed in § 252.302, then those requirements shall be met.

 Section 252.304(b)(3)(vi) and (vii) (relating to personnel requirements), regarding initial and ongoing demonstration of capability requirements, is proposed to be amended to include additional detail regarding the concentration at which to prepare the four aliquots of the analyte. The proposed amendments clarify that the analyses of the four aliquots shall be analyzed consecutively but can occur on one or multiple days and provides additional clarification to explain how to evaluate the final results.

 Editorial changes and clarifications are proposed throughout § 252.306 (relating to equipment, supplies and reference materials). Clarifications are proposed to the requirements for equipment, supplies and reference materials in subsection (c) to explain that the laboratory shall ensure that equipment, supplies and reference materials, including test instruments, meet the specifications required of the application for which it is used.

 Additional detail is proposed to be added to § 252.306(f) to explain the documentation requirements for both balance calibrations and verifications, pH meter calibrations, refrigerators, incubators and other laboratory equipment. The term ''working'' is proposed to be added to subsection (f)(7)(ii) and (8)(iv) under ''refrigeration equipment and freezers'' and ''incubators, water baths, heating blocks and ovens,'' respectively. The laboratories would be required to monitor the temperatures of these types of equipment each ''working day'' when ''in use.'' The term ''working day'' would be interpreted as a day when the laboratory is open for business or laboratory staff are working in the laboratory, or both. As an example, when laboratories are closed for business and laboratory staff are not working in the laboratory, temperatures would not need to be taken. Conversely, in subsection (f)(8)(iv), when an incubator, water bath, heating block or oven is used as an incubation unit for microbiology, the temperature shall be monitored each day that the incubator is in use. Thus, a laboratory shall monitor microbiology incubators even when the laboratory is closed for business when the microbiology incubation units are in use. The requirement to calibrate a pH meter with standards that bracket the pH range of samples is proposed to be deleted from subsection (f)(5). Specific detail is proposed to be added to the requirements for volumetric dispensing devices and graduated sample containers in subsection (f)(9) and (10). Subsection (g) is proposed to be amended to include a requirement to track laboratory supplies that are essential to obtain analytical results in the laboratory's recordkeeping system.

 Subsection (h) is proposed to be amended to add ''media'' to ensure that media records are maintained in the same manner as standards and reagents. Laboratories are not permitted to use expired materials for testing or analysis of compliance samples. During discussions with the LAAC, the Department suggested that the laboratories be required to remove expired materials from the laboratory. However, the public and the LAAC suggested that these materials did not need to be removed, but segregated to ensure they were not used. The requirement to segregate expired materials from unexpired materials in the laboratory is proposed to be added to subsection (h)(6) to ensure that they cannot be used.

 During recent onsite assessments performed by the Program, laboratories have increasingly been found to be in violation of temperature requirements for microbiology incubators. They were either using incubators that cannot maintain the mandated temperature ranges or were overloading the incubators and they could not recover back to the minimum temperature within acceptable time frames. In light of this, subsection (j) establishing a requirement to perform temperature distribution studies for microbiology incubators is proposed to be added. The requirements for frequency and minimum requirements are outlined. Laboratories will be required to develop a procedure to perform this study and the procedure must be based on the specific type and size of incubation unit and incubators that do not maintain constant temperatures cannot be used.

 Editorial changes to § 252.307 are proposed. This section does not regulate the collection of compliance samples when these samples are not collected by accredited laboratories. Many sample collections are performed by individuals with little or no experience in proper sample handling, collection and preservation procedures. To the best of their ability, the laboratories that collect, receive and analyze the compliance samples shall ensure that the samples meet the requirements for a valid sample analysis. Subsection (j) is proposed to be added for laboratories to develop and maintain instructions for sample collection and preservation. The proposed subsection specifies what types of information these instructions must include, which will be dependent on the type of analyte being tested and for what compliance purpose, and that these instructions shall be made available to both laboratory employees that collect the samples and customers and clients that collect samples.

Subchapter D. Quality assurance and quality control requirements

 During public meetings with the LAAC, procedures for handling environmental samples outlined in § 252.401(f) were repeatedly discussed and comments regarding the Department's proposals and expectations were received. It was suggested that additional detail is needed to more fully explain how and when samples shall be checked and how the documentation of these checks shall be maintained. The existing regulation does not specify when the checks shall be made, only that the environmental laboratory is responsible for these checks and that the laboratory shall ensure that each check is appropriate to determine the validity of the test and that the checks shall be recorded. The requirement to verify and document the condition of the samples by the environmental laboratory is proposed to be clarified to explain that both chemical and thermal preservation shall be checked for all samples, that sample pH for all samples is analyzed for chemistry; whole effluent toxicity and radiochemistry fields; and that samples shall be checked for residual chlorine if the requested test will be negatively impacted by the presence of chlorine. A requirement to include the identification of the individual receiving the sample at the laboratory is proposed to be added.

 Subsection (j) does not currently require unique identification for test reports or a requirement to identify amendments to test results or reports. This has resulted in test reports and results being issued or amended by laboratories that are easily misunderstood and untraceable to the original report. The proposed amendment to subsection (j) adds items to be included in a test report from the laboratory, including the date in addition to the time of sample preparation and analysis for tests with short holding times, a unique test report identifier or code, and requirements for amendments to test reports.

 Subsection (o) is proposed to be added to mandate that laboratories identify all opinions and interpretations on test reports and include an explanation for the basis of the opinion or interpretation.

 Section 252.402 (relating to essential quality control requirements—chemistry) is proposed to be amended to add additional detail with regard to the raw data records that are necessary to permit reconstruction of the analytical testing, such as initial calibration (subsection (c)), method blank (subsection (g)) and laboratory control samples (subsection (h)).

 This section is proposed to be amended to add standards necessary for the quality control protocols mandated by Chapter 252 when the approved methods do not include acceptance criteria requirements. Many analytical methods do not include specific acceptance criteria for one or more required quality control elements that Chapter 252 mandates. The proposed amendment to subsection (f)(6) provides that when a method exists that does not include minimum acceptance criteria for one or more quality control measures the environmental laboratory shall use the acceptance criteria established in an equivalent method. An equivalent method would be one where the same or similar analyte is analyzed using the same or similar methodology/technology. For example, a laboratory is using a spectrophotometric method for the analysis of nitrate that does not have acceptance criteria for the LCS recovery, such as Standard Methods 4500-NO3 E. EPA 353.2 is also a spectrophotometric method for the analysis of nitrate and the LCS recovery for the LCS is 90—110% of the true value. The laboratory would use the 90—100% recovery limits for the evaluation of the LCS when analyzed by SM 4500-NO3 E. The proposed amendment also provides specific information regarding how to develop acceptance criteria for quality control measures when an equivalent method is not available.

 Many laboratories have been under the misunderstanding that because Chapter 252 states that data may be reported with data qualifiers, then the data associated with data qualifiers is acceptable to be reported without determining if qualified data is acceptable to the Department. To address this misconception, it is proposed to delete language in § 252.402(f)(8) that describes when sample results may be useable because the laboratories regulated by this section should not be making the decision about usability of data.

 Editorial changes and amendments are proposed throughout § 252.404 (relating to essential quality control requirement—microbiology). The documentation requirements for equipment, supplies and reference materials in this section were updated to ensure that necessary items for the reconstruction of the measurement are maintained. Subsection (d)(7) is proposed to be added to clarify that the heterotrophic plate count and bacteriological water quality test ratio analyses shall be performed by a laboratory accredited under Chapter 252. Subsection (g)(7) is proposed to be added to explain the requirements for sterility checks of Quanti-Tray^TM sample trays. Proposed subsection (h) includes language that mirrors current language from § 252.401 explaining that laboratory materials cannot be used after their expiration date unless re-evaluated by a procedure approved by the Department.

 Subsection (j) is proposed to be added to clarify that all quality control checks outlined in this section shall be performed after the laboratory receives the material. The sterility and efficacy of media and other microbiological supplies are directly affected by exposure to extreme temperatures and other environmental factors. The Department requires that laboratories verify the sterility and efficacy of the received materials for microbiological testing after the material is received by the laboratory.

Subchapter E. Proficiency test study requirements

 Section 252.501(p) (relating to proficiency test study requirements) is proposed to be added to explain that proficiency test studies that are not handled, managed, analyzed or reported in accordance with this section will be invalidated. This section includes the specific requirements for a laboratory when ordering, receiving, handling, analyzing and reporting proficiency testing studies. Laboratories that do not manage proficiency test studies in accordance with this section may not use the inappropriate proficiency test study results for accreditation purposes.

Subchapter F. Assessment requirements

 The term ''onsite'' is proposed to deleted from § 252.601 (relating to assessment requirements) as used in the context of onsite assessments, when appropriate, to allow the Department to explore and implement alternative assessment procedures in lieu of onsite assessments. Subsection (d) is proposed to be amended to explain that the Department may deny, suspend or revoke a laboratory's accreditation in accordance with Subchapter G (relating to miscellaneous provisions) if the Department finds that the laboratory's noncompliance is so severe that action is warranted before the Department issues an assessment report or the laboratory submits a corrective action report. Subsections (e) and (h) are proposed to be amended to better explain the requirements for a corrective action report, including how to prepare the report and what information and other supporting documentation shall be provided as evidence of the laboratory's implementation of its corrective action.

Subchapter G. Miscellaneous provisions

 Editorial changes are proposed throughout this sub-chapter, including deletion of ''onsite'' as previously explained. Sections 252.702(d), 252.703(e) and 252.704(c) (relating to revocation; suspension; and voluntary relinquishment) are proposed to be amended to state that the laboratory may notify the customers of a revocation or suspension in a manner approved by the Department instead of on a form approved by the Department. It is proposed to add failure to maintain test instruments, equipment, supplies and reference materials meeting the specifications required to produce valid analytical results as grounds for denial, suspension and revocation of accreditation in § 252.701(b)(17) (relating to denial of application) and §§ 252.702(b)(18) and 252.703(c)(7). Failure to manage proficiency test study results in accordance with § 252.501 is proposed to be added as a cause for revocation and suspension of accreditation in §§ 252.702(b)(11) and 252.703(c)(8). Three additional reasons for suspension of accreditation are proposed in § 252.703(c), including failure to submit an acceptable corrective action report, failure to correct deficiencies from an assessment and failure to implement corrective action. This would provide the Department greater flexibility in enforcement of Chapter 252 and 27 Pa.C.S. Chapter 41. Currently, the Department's only option in response to a violation of these provisions is revocation of accreditation.

 Editorial changes are proposed throughout § 252.705 (relating to use of accreditation), including deleting ''NELAC.'' Subsection (c) is proposed to be amended to include expiration of accreditation as one of the events precipitating the sanctions outlined in that subsection.

 The Department found numerous continued violations of the recordkeeping requirements in § 252.706 (relating to recordkeeping) during its regular onsite assessments and data review. To address this and to clarify the recordkeeping requirements, proposed amendments to subsection (b) specify some of the specific requirements for records that shall be maintained to allow reconstruction of laboratory activities. Subsection (c) is proposed to be amended to clarify that records, not just data, shall be recorded promptly and legibly and that if the individual making the observation is not the individual creating the record, then both individuals and their responsibilities shall be identified and documented.

 Section 252.708 (relating to reporting and notification requirements) incorporates the reporting and notification requirements in Chapter 109 (relating to safe drinking water) by reference. In the previous amendment to this section, subsection (a) incorrectly included ''microbiological'' as a type of test that could be reviewed within 24 hours of acquisition of sample results and radiochemistry was missing from this section. The term ''microbiological'' is proposed to be deleted from subsection (a)(2) and ''radiochemical'' is proposed to be added to subsection (a)(3). Paragraphs (4)—(6) are proposed to be added to subsection (a) to provide that microbiological results shall be read within 30 minutes of the end of the incubation, laboratory control samples shall be analyzed at or below the Maximum Contaminant Level and a clarification that only those analytical results that meet all method, regulatory and permit requirements for sample collection, preservation, holding time, sample analysis and quality control performance may be reported to the Drinking Water Environmental Reporting system unless the Department specifically approves the results to be reported.

F. Benefits, Costs and Compliance

Benefits

 The most significant benefit of this proposed rulemaking will be the benefit of clear, concise and improved regulations for the regulated community. The proposed amendments will allow for better understanding and increased compliance with the requirements and thus result in an improvement in the overall quality of the data produced by environmental laboratories. Laboratories, particularly small laboratories, will benefit from allowing a laboratory supervisor to be absent for up to 21 days, rather than the current 16 days, and be replaced by a qualified staff member. Several of the laboratory supervisor areas of experience qualifications were reduced from 2 years to 1 year. The proposed rulemaking deletes the requirement for the Department to conduct onsite assessments, thus allowing the Department to explore and utilize advances in technology to perform offsite assessments which can substantially reduce overall costs to the Program and the regulated laboratories.

 This proposed rulemaking also adds specific requirements for NELAP laboratories. The current TNI Standard, which NELAP laboratories shall meet, is silent or lacking in specific requirements for several necessary standards. Requiring that all NELAP laboratories adhere to these regulations will ensure that all laboratories performing testing or analysis of compliance samples for the Department are meeting the same minimum standard.

 Improved data quality will allow the Department, the regulated community and the citizens of this Commonwealth to make better and more informed decisions concerning the protection of the environment and the protection of public health, safety and welfare. Accurate laboratory results are critical to achieving the goals of the environmental laws which are covered by the regulations.

Compliance costs

 The direct costs of the proposed rulemaking will be payment of the proposed fees. Chapter 41 of 27 Pa.C.S. requires that the fees be set in an amount sufficient to cover the cost of establishing and maintaining a laboratory accreditation program. These costs will vary depending upon the type of testing and analyses that the environmental laboratory chooses to perform. Laboratories that require extensive staff time to accredit such as large commercial laboratories and NELAP laboratories will pay a higher accreditation fee.

 The renewal fee for State accreditation is proposed to be increased by $200 per year while the renewal fee for NELAP applicants is proposed to be increased by $750 per year. The proposed renewal application fees will increase for all laboratories at a rate of approximately 28%. Each laboratory is also responsible for paying the appropriate category fee associated with its requested scope of accreditation, such as microbiology, trace metals, volatile organics, and the like. The total accreditation fee for each laboratory is the renewal application fee plus each appropriate category fee. Each proposed category fee is proposed to be increased by between $100—$200 depending on the complexity of each category. The proposed fees for medium to large accredited laboratories are likely to increase by approximately 20—30% depending on the requested scope of accreditation. The proposed rulemaking contains a fee structure that is responsive to the needs of small laboratories. Specifically, increased category costs for smaller laboratories will be minimal as the fees for the Basic Non-Potable Water and Basic Drinking Water fee categories are proposed to be increased by $300. The current annual fee paid by these environmental laboratories is $1,250, and the proposed fee change would result in an annual fee of $1,550. Laboratories seeking accreditation for these two categories represent the majority of the applicant laboratories as well as the smallest of the regulated laboratories. In addition, the proposed fee structure includes changes including separation of the microbiology category into ''basic'' and ''complex'' to ensure that laboratories that are performing the more complex testing, which requires additional staff time and oversight, cover the costs of the accreditation.

 Indirect costs will be related to the individual laboratory's implementation of the new requirements. Many in the regulated community are already in compliance with the additional requirements itemized in this proposed rulemaking and will not incur any additional costs for implementation. Others will be required to update or develop standard operating procedures and update recordkeeping procedures.

 Cost savings will occur in the regulated community because the new and clarified requirements will enable laboratories to better understand the applicable requirements and should reduce the number of violations found during assessments, thus reducing the amount of time and money necessary to correct these violations.

Compliance assistance plan

 Aside from the proposed fee changes, the proposed amendments are minor and in most cases clarify existing requirements or make current requirements less stringent. The Department does not believe that a compliance assistance plan tailored to the proposed rulemaking is necessary. However, the Department will continue its ongoing compliance assistance efforts.

 The ultimate goal of the compliance assistance effort will be improving an environmental laboratory's ability to produce valid and defensible data for use by the Department, the regulated community and the public. Several areas where compliance assistance is necessary are general laboratory operation, correct performance of specific test procedures and documentation of laboratory activities. Compliance assistance in these areas has been made available to all environmental laboratories regardless of size throughout this Commonwealth.

Paperwork requirements

 This proposed rulemaking does not include any additional forms, reports or other paperwork to be submitted.

G. Pollution Prevention

 This is not applicable to this proposed rulemaking.

H. Sunset Review

 These regulations will be reviewed in accordance with the sunset review schedule published by the Department to determine whether the regulations effectively fulfill the goals for which they were intended.

I. Regulatory Review

 Under section 5(a) of the Regulatory Review Act (71 P.S. § 745.5(a)), on July 29, 2016, the Department submitted a copy of this proposed rulemaking and a copy of a Regulatory Analysis Form to the Independent Regulatory Review Commission (IRRC) and to the Chairpersons of the House and Senate Environmental Resources and Energy Committees. A copy of this material is available to the public upon request.

 Under section 5(g) of the Regulatory Review Act, IRRC may convey comments, recommendations or objections to the proposed rulemaking within 30 days of the close of the public comment period. The comments, recommendations or objections must specify the regulatory review criteria in section 5.2 of the Regulatory Review Act (71 P.S. § 745.5b) which have not been met. The Regulatory Review Act specifies detailed procedures for review prior to final publication of the rulemaking by the Department, the General Assembly and the Governor.

J. Public Comments
