**Information Collection Request Section 1:**  **Part A of the Supporting Statement**
**1. Identification of the Information Collection 1(a)**  **Title of the Information Collection** Laboratory

Quality A ssurance Evaluation Program for Anal ys is of Cryptosporidium under the Safe Drinking Water Act (Renewal) **OMB Number: 2040**  **- 0246**  **U.S. EPA**  **T racking Number**  **: 2067.0**  **4 1(b)**  **Short Characterization** The U.S. Environmental Protection Agency (EPA) is requesting a renewal of the information collection request (I CR) for the Laboratory Quality Assurance Evaluation Program for Anal ys is of Cryptosporidium under the Safe Drinking Water Act (Lab QA Program). This voluntary program applies to public and private laboratories that analyze water samples for Cryptosporidium . The program will help ensure that laboratories meet the quality assurance and the updated quality control criteria in Appendix J when using EPA M ethods 1622 (EPA
- 815
- R
05
- 001, http://www.epa.gov/nerlcwww/documents/1622de05.pdf ) or 1623 (EPA
- 815
- R
- 05
- 002, http://www. epa.gov/nerlcwww/documents/1623de05.pdf ) for determin ing the identity and concentration of Cryptosporidium in source water by filtration, immunomagnetic separation (IMS), and immunofluorescence assay (IFA) microscopy
. EPA Methods 1622 and 1623 were designated for Cryptosporidium analy ses in the LT2ESWTR (40 CFR 141.704); EPA Method 1623.1 (EPA 816
- R
- 12
- 001 , http://water.epa.gov/scitech/drinkingwater/labcert/up load/epa816r12001.pdf ) was approved as another option for LT2ESWTR analyses per the June 28, 2012 Federal Register Notice , “ Expedited Approval of Alternative Test Procedures for the Anal ys is of Contaminants Under the Safe Drinking Water Act ” ( http://water.epa.gov/drink/resources/new.cfm )

. In formation collection activities required for laboratories seeking State Certification include: laboratory documents with resumes for each staff member; standard operating procedures (SOPs); Ongoing Precision and Recovery (OPR) control charts; Matrix Spike control charts; training records for all anal ys ts/technicians ; proficiency testing (P T) results; and a cop y of any certificates as documentation of equipment maintenance ; participating in off
- site evaluation activities, including submitting positive staining control and OPR slides and performing online analy st evaluation ; and participating in a 1 to 2 day on - site evaluation of laboratory

performance and data quality , including performing an independent count of a blind slide
. All materials are being collected b y participating S tate c ertification programs. This information colle ction will provide States with data to verify that the laboratories are capable of producing reliable data from the anal ys is of Cryptosporidium using EPA Method 1622 , EPA Method 1623 or EPA Method 1623.1
.2

The information collection will involve approxima tely 4 5 laboratories at a total cost of approximately

$ 5 90 , 858 .79 or 3504 labor hours annually . The total number of laboratories includes 45 laboratories that participate in the proficiency testing program. The estimated total State burden, including contractual costs, is estimated at $ 212,916.00 or 1968 labor hours annually , based on an estimate of 20 participating States (Appendix K)
. The estimated total Agency burden, including contractual costs, is estimated at $ 125,170.15 or 1953 labor hours annually (Appendix K). **2. Need For and Use of the Collection 2(a)**  **Need/Authority for the Collection** The information collection is needed b y EPA to support the Cryptosporidium data gathering activities that are required under the Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR). The Lab QA Program is being renewed because the Cryptosporidium laboratory

evaluation program must continue for the duration of the LT2ESWTR
. Renewing the Lab QA Program will help ensure that qualified laboratories are available to public water sy s tems. **2(b) Practical Utility/Users of the Data**  In formation collected under th e Lab QA Program will be used by States and EPA to verify that Cryptosporidium occurrence data are generated b y qualified laboratories that can perform the anal ys es acceptably . Use of qualified laboratories for source water monitoring by drinking water uti lities will help ensure that the data collected are of known and reliable quality
. Data quality could potentially be compromised in the absence of Laboratory Certification Programs
. A list of laboratories that meet th e evaluation program criteria will be made available to the public by

States and/or EPA at http://water.epa.gov/lawsregs/rulesregs/sdwa/lt2/lab_home.cfm and will provide a resource to aid drinking water utilities (an d others interested in monitoring water for Cryptosporidium occurrence for the protection of public health) in selecting a qualified anal ytical laboratory. **3. Non -**  **duplication, Consultations, and Other Collection Criteria 3(a)**  **Non -**  **duplication** The information requested from the respondents under this I CR is not available from other sources. The information requested will be used to assess the current a bility of a laboratory to reliably

anal yz e Cryptosporidium in water using EPA Method 1622 , EPA Method 1623 or EPA Method 1623.1 . Information submitted for previous programs, such as the Information Collection Rule, is not applicable because older analy tical methods were used and quality control requirements were different. The determination that this information is not available f rom other sources was made b y the Office of Ground Water and Drinking Water Technical Support Center3

(TSC), which will be administering the Lab QA Program, and which has worked closel y since 1996 with the capable laboratories that will be affected by this information collection. **3(b) Public Notice Required Prior to ICR Submission to O**  **ffice of M**  **anagement and B**  **udget** On September 5 , 20 13 ( 78 FR 5464 3 ), EPA sought comments on this I C R pursuant to 5 CFR 1320.8(d). EPA received two comments during the comment period, which are addressed in the I CR. C op ies of the previous four Federal Register notice s are attached in Appendi ces A , B, C, and D
. The ICR was last renewed in 200 9 (See Appendix D ). EPA has developed a webpage to provide further information on the program. The website can be accessed at http://water.epa.gov/lawsregs/rulesregs/sdwa/lt2/lab_home.cfm
. **3(c) Consultations**  EPA conducted meetings with representatives of the drinking water treatment industry and the community

of laboratories expected to seek EPA recognition under the Laboratory Quality Assurance Evaluation Program in Cincinnati, OH, on January 23 and March 12
- 13, 2001, and in Washington, DC, on February 13
- 14, 2001. EPA presented and discussed draft plans for the laboratory

evaluation program at these meetings and sought input from the drinking water utility

and laboratory

representatives that attended these meetings. In addition, EPA has been working with States and EPA Regions to integrate Cryptosporidium laboratory approval/oversight into existing State certification/accreditation programs. Participating State s will approve and oversee laboratories that support the second round of LT2ESWTR monitoring. L aborato ries were asked to estimate the loaded cost of legal, clerical, technical and management personnel per hour, and average cost for anal ys es of a sample. Inaddition, laboratories were asked to estimate the hours that each category of personnel would spend to complete the activities associated with submitting a laboratory evaluation application package, performing off

- site evaluation activities, preparing and hosting on
- site evaluation, and performing and reporting two sets of PT samples per year . L aboratories were also asked to estimate the operation and maintenance costs associated with PT samples and audits. Six laboratories have supplied burden estimate information for participating in a state laboratory certification program:

· Charlotte
- Mecklenberg Utilities

– Environmental L aboratory Services

· Pennsylvania Department of Environmental Protection, Bureau of Laboratories

· Environmental Science Corporation

· Bio Vir Laboratories, Inc.

· CH Diagnostic & Consulting Service, Inc.

· Underwriters Laboratories, Inc. States were asked to estimate the loaded cost of legal, clerical, expert, technical or certification officer, and management personnel per hour. In addition, states were asked to estimate the hours that each category of personnel would need to complete the activities associated with reviewing a laboratory evaluation application package, conducting off
- site evaluation activities, conducting on
- site evaluations, notifying laboratories of certification status,4

reviewing and tracking PT samples, coordinating follow
- up activities for failed PT results and maintaining a list of certified laboratories on the State website. Two states have supplied burden estimates for providing laboratory certification:

· New Jersey

Department of Environmental Protection, Office of Quality Assurance

· Kentucky Department of Environmental Protection, Division of Water During the public comment period announced in the September 5, 2013 Fe deral Register N otice, EPA received two sets of comments

– one from a commercial laboratory and another from the American Water Works Association (AWWA) . A number of the comments address matters beyond the scope of this I CR and will be addressed separatel y . Several of the comments pertain to the scope of the I CR and were addressed as follows. AWWA asked that EPA “Advise [PWSs] on the status and timeline for the current lab approval process.... b y 12/31/13 and provide a regularl y updated, centralized list of all approved labs and the states that approved each .” Laboratories are being approved to support Round 2 monitoring on an ongoing basis. The latest information regarding laboratory approval status is posted on the EPA Website http://water.epa.gov/lawsregs/rulesregs/sdwa/lt2/lab_home.cfm
. EPA’s Technical Support Center will maintain a list of links to State Web sites naming certified laboratories as well as the list of certified la boratories on EPA’s website. AWWA commented that there was a “Lack of information upon which water sy stems can organize and budget procurem ent of (qualified lab) services.” A complete section on “ Contracting for Laboratory Services” is included in the Pub lic Water System Guidance Manual for the Long Term 2 Enhanced Surface Water Treatment Rule (LT2 Rule) . This guidance manual for PWSs affected b y the rule provides information on laboratory contracting, sample collection procedures, and data evalu ation and interpretation advice available at http://www.epa.gov/safewater/lt2/index.html . Responses to frequentl y asked questions (FAQs) on sampling, anal ys is, and data reporting questions for the LT2 rule also are available on this website. AWWA also suggested that “EPA cannot require use of EPA Method 1623.1 or change the ongoing precision and recovery (OPR) requirements for EPA Methods 1622 or 1623 without rule making....” The Agency approved Method 1623.1 a s another option for LT2ESWTR anal ys es pursuant to the June 28, 2012 Federal Register Notice , “ Expedited Approval of Alternative Test Procedures f or the Anal ys is of Contaminants under the Safe Drinking Water Act. ” EPA has also used this I CR actio n to provide notice of an update of the 2009 laboratory quality assurance procedures for Methods 1622 and 1623 to reflect that improved recovery for Cryptosporidium in ongoing precision and recovery (OPR) samples is now routinely achievable as labs have gained experience with Cry ptosporidium measurement. M inimum recovery is based on an updated and expanded data set from laboratories using Method 1623 and should provide a better assessment of laboratory performance than the previous value for the following reasons: 1) the data set is more recent; and 2) the sample size is more than twice as large as the 2009 sample size. Lastl y, b oth the commercial laboratory and AWWA voiced concern regarding the5

increased costs for lab approval. EPA notes that the appro ach for Round 2 creates consistency with the approach for approval/oversight of laboratories for all other regulated anal yt es and represents an opportunity for greater efficiencies as the oversight for Cryptosporidium is integrated into existing programs. EPA believes that the net impact of this approach on anal ytical costs will be marginal as any fees imposed by certification bodies are distributed across the laboratory

analy ses. For specific burden breakdowns, ref er to the Participating Laboratories Seeking Certification and State Annual Burden tables in Appendix K of this Supporting Statement. **3(d) Effects of Less Frequent Collections**  Under the Lab QA Program, laboratories anal yz e single
- blind proficiency test samples 2 times per year. This frequency enables States to independentl y verify that laboratories perform in an acceptable manner. Less frequent proficiency test samples may not s ufficiently

capture a laboratory ’s performance over time. Laboratories report proficiency test results to the PT provider within 14 day s of sample receipt. Reporting proficiency test sample results at this frequency allows States to respond in a timely manner to any problems the laboratory may be having with anal ys is of Cryptosporidium in water. **3(e) General Guidelines**  The Lab QA Program adheres to all of OMB’s general guidelines for information collection. **3(f/g) Confidentiality/**  **Sensitive Questions** The Lab QA Program does not ask any confidential or sensitive questions. **4.

The Information Collected -**  **Agency Activities, Collection Methodology, and Information Management**  **5(a) Agency Activities**  Agency (EPA Regions and Office of Ground Water and Drinking Water) activities associated with the L ab QA Program consist of the following:

· Assisting State Certification Officers with review of laboratory evaluation application packages

· Assisting State Certification O fficers with off
- site evaluation activities, including slide evaluation and online analy st evaluation

· Assisting State Certification Officers with on
- site evaluation activities , including independent count of blind slides

· Assisting State Certification Offic ers with interpretation of P T results

· Maintaining a list of links to State websites and/or certified laboratories on EPA’s website **5(b) Collection Methodology and Management**  **Laboratories Seeking State C**  **ertification** L aboratories interested in obtaining S tate certification of their capability to perform anal ys es using EPA Method 1622, EPA Method 1623 or EPA Method 1623.1 and continuing to demonstrate, proficient and reliable detection and enumeration of Cryptosporidium in surface water sources for public water s ys tems may contact State personnel responsible for laboratory certification
. Certified laboratories are responsible for notifying the S tate of losses of key personnel or essential equipment and changes in policies or procedures that directly affect the validity of data or any other change affecting the capability of the laboratory , including change in laboratory location. Participating laboratories are to also demonstrate ongoing capability and method performance b y following all applicable method quality control (QC) procedures, anal yz ing P roficiency T esting (PT) samples (2 times per year), submitting requested data to the S tate, and participating in periodic evaluations. The Method procedures have been updated to reflect that the minimum recovery for Cryptosporidium in ongoing precision and recovery (OPR) samples is now 33 percent (See Appendix J ). Laboratories are to document a minimum of 33 percent recovery

for OPR samples in an updated QC chart prior to anal ys is of L T2ESWTR samples at the frequency

required in Section 9.7 of EPA method 1622/1623 and Section 9.8 of Method 1623.1. If a laboratory submits PT results more than 2 standard deviations below the mean value of all participating labs , EPA may recommend additional follow
- up action to demonstrate that the laboratory ’s p erformance remains acceptable. Additional actions may include submission of PT slides, repeat anal ys es, providing additional QC data, and investigation of problem s with reagent s and equipment. Repeated failure to demonstrate laboratory capability and acceptable method performance may result in suspension or downgrading of approval status as outlined in 2009 Federal Register Notice (https://federalregister.gov/a/E9
- 4009 ) (See Appendix D).”8

EPA expects that State certification personnel , or their designee, will request a package with documentation of laboratory personnel status, equipment maintenance, standard operating procedures, training records, and QC charts. EPA expects that the State will evaluate the package for completeness , and would generall y follow these steps : 1. The laboratory

will send positive staining control and OPR slides for evaluation by State certif ication officer or their designee (Appendix H ). 2. The laboratory

will order on - si te audit package consisting of two vials containing 50 mL blind samples, 2 vials of artificial matrix, 2 IMS control samples, and 2 anal ys t evaluation slides. One slide is required per analyst and a back up slide. These will be used in presence of an auditor; therefore, on - site evaluation date should be within product expiration. Each anal ys t will perform an independent count of one slide. The results and anal ys t evaluation slides and associated examination forms will be submitted to a State , if requested
. 3. The laboratory will schedule an online anal ys t evaluation of performance for microscopists to demonstrate their ability to identify Cryptosporidium oocy sts . An example report from the internet anal ys t evaluation is shown in Appendix I. 4. The S tate will conduct one 2
- day on - site evaluation that will primarily focus on anal ys t skills and data recording. Laboratory personnel may be asked to prepare a fresh OPR and posit ive control for review during the on
- site evaluation. In addition, laboratory personnel will be asked to use the blind oocy st suspensions ordered in #2 for spiking reagent water and an IMS control in the presence of an auditor, and then complete the anal ys es within applicable method holding times and send results to the S tate (Appendix G ). 5. The State will send the laboratory a report aft er the evaluation is complete. The laboratory is then asked to provide written responses to any deficien cies identified in the report. Provided all responses to the deficiencies cited in the report are acceptable, the State will then base its decision for laboratory certification on PT results, quality of the positive control and OPR slide, slide counts, onl ine anal yst evaluation , on - site evaluation and recovery values for blind anal ys es initiated during the on
- site evaluation (See Appendices G, H, and I ). **5(c) Small Entity Flexibility**  The Lab QA Program is a voluntary program; any entity not interested in gaining approval to support LT2 ESWTR is not required to participate
. Small businesses are defined as any business that is independently owned and operated and not dominant in its field as defined b y the Small Business Administration (SBA) regulations under Section 3 of the Small Business Act. Small businesses may

opt to seek state recognition of laboratory capability to perform Cryptosporidium water analy ses using onl y one version of EPA Method 1622 /1623 or E PA Method 1623 .1 , as opposed to being evaluated for multiple versions, and reduce the burden associated with participation in the L ab QA Program.9

**5(d) Collection Schedule**  Laboratory

certification is voluntary
. Laboratories that have successfull y completed the audit process will not be evaluated more than once per two - ye ar period. TSC’s oversight of LT2ESWTR laboratories during Round 1 represented an exception to the traditional laboratory

certification/accredi tation approach. At the time, labs and States had limited experience with Cryptosporidium monitoring. With the experience gained b y laboratories, as well as States, during the first round of monitoring, all parties should be more comfortable with the monit oring and laboratory requirements, thus enabling interested States to take a primary role in lab certification while EPA provides guidance and technical support. The approach for Round 2 creates consistency with the approach for approval/oversight of laboratories for all other regulated anal yt es and is provided for in the LT2ESWTR rule. A number of States have already expressed an interest in adding Cryptosporidium laboratory approval to their programs and have participated in TSC’s Cryptosporidium Laborato ry Certification Officers Training Course in 2010, 2011 and 2013. **6. Estimating the Burden and Cost of the Collection 6(a)**  **Estimating Respondent Burden** Below are summaries of respondent burden hours for this information collection. EPA consulted with six respondents from the community of laboratories that have voluntarily applied for State certification to perform Cryptosporidium anal ys es using EPA Method 1622 , 1623 , and 1623.1, and 2 respondents from the community of States integrating certification programs to obtain burden hour estimates. For specific burden breakdowns, refer to the Participating Laboratories Seeking Certification and State Annual B urden tables in Appendix K . The burden estimates were also addressed in the Federal Register Notice published in September 2013 (See Appendix E ). Based o n the first round of LT2 ESWTR monitoring, EPA estimates that 45 laboratories will participate in State Certification Program s , of which 15 are private and 3 0 are state or local government entities . EPA estimates that 20 States will develop programs to certify Cryptosporidium laboratories
. Twenty- one states have Cryptosporidium laboratories within their state boundaries and 19 states responded positively to an industry survey [ASDWA]. **Activities for Laboratories Seeking State Certification**  Laboratories seeking State certification for anal ys is of Cryptosporidium will complete an application package, including: laboratory documents with resumes for each staff member; standard operating procedures (SOPs); Ongoing Precision and Recovery charts; and Matrix Spike control charts; training records for all anal ysts/techn icians; data package; proficiency testing (PT) results; and a cop y of any certificate s as documentation of equipment maintenance. Since laboratories will submit the application no more than 1 time per 2 year period, the number10

of laboratories expected to s ubmit applications were evenl y distributed over a 2 year - period to estimate burden hours and costs per ye ar (e.g., laboratories seeking c ertification , 45 laboratories/2 ye ars = approximately 22.5 labs/ye ar). Burden hours associated with submitting the comp leted application package for the laboratories appl yi ng for certification are estimated at 2 93 labor hours per ye ar. Laboratories seeking certification will also complete off
- site evaluation activities including submitting positive staining control and OPR slides, and performing online anal ys t evaluation . Since laboratories have to complete off
- site evaluation activities no more than 1 time per 2 year period, the number of laboratories expected to complete off
- site evaluation activities were evenl y distributed over a 2 ye ar - period to estimate burden hours per year (e.g., laboratories seeking c ertification , 45 laboratories/2 ye ars = approximately 22.5 labs/ye ar). Burden hours associated with completing off
- site evaluation activities for the laboratories applying for certification are estimated at 486 labor hours per year. Each laboratory

seeking State c ertification will participate in a 1 to 2 day o n - site evaluation . The burden hours associated with this task include time required to attend short briefings b y the auditors before and after the audit, demonstrate the techniques for the methods for which they

are seeking certification , participate in di scussions with the auditors, and respond to any deficiencies noted in the audit report. Laboratories will purchase blind spikes and slides from a qualified vendor and will process samples to demonstrate method performance and perform an independent count o f a blind slide . Because laboratories will undergo an on
- site evaluation no more than 1 time every 2 ye ars, the number of laboratories expected to be evaluated were evenl y distributed over a 2 ye ar period to estimate burden hours per year (e.g., laboratori es seeking c ertification , 45 laboratories/2 ye ars = approximately 22.5 labs/year). Burden hours for all laboratories appl yi ng for certification are estimated at 889 labor hours per ye ar (Appendix K). Laboratories will anal yz e a set of proficiency test samples, which may include confounding organisms (3 samples per set) 2 times a year for each method version for which they are seeking certification . The burden estimates associated with this task include labor associated with analyzing samples and documenting the data for each proficiency test set. Burden hours for all laboratories seeking c ertification and anal yz ing 1 set of proficiency test samples 2 times a year are estimated at 1 541 labor hours per ye ar (Appendix K). It is estimated that 4 laboratorie s seeking State certification will perform more than 1 method version and will perform an additional set of PT samples for each additional method version 2 times a year. Burden hours for laboratories seeking certification and performing an additional set o f PT samples for each additional method version are estimated at 1 37 labor hours per year (Appendix K). EPA estimates that a small subset of laboratories seeking State certification will have to perform follow
- up activities based on inadequate QA/QC, faile d OPRs, incomplete records, delayed communication to the S tate or poor PT results. Burden hours for laboratories seeking c ertification and performing follow
- up activities based on inadequate QA/QC, failed OPRs, incomplete records, delayed communication or poor PT results are estimated at 1 58 labor hours per year (Appendix K).11

**Activities for State**  **s Integrating Cryptosporidium**  **C ert** **ification P**  **rograms** States integrating certification programs for anal ysis of Cryptosporidium will review a laboratory ’s application package, including: laboratory documents with resumes for each staff member; standard operating procedures (SOPs); Ongoing Precision and Recovery charts; Matrix Spike control charts; training records for all anal ysts /technicians; data packages, proficiency testing (PT) results; and a cop y of any certificate s as documentation of equipment maintenance. Since laboratories will submit the application no more than 1 time per 2 year period, the number of laboratories expect ed to submit applications were evenl y distributed over a 2 year - period to estimate burden hours and costs per ye ar (e.g., laboratories seeking c ertification , 45 laboratories/2 ye ars = approximately 22.5 labs/ye ar). Burden hours associated with all States reviewing completed application package s for the laboratories appl yi ng for certification are estimated at 416 labor hours per ye ar (Appendix K)
. States integrating certification programs will also review off
- site evaluation activities including positive staining control and OPR slides, and online anal ys t evaluation . Since laboratories have to complete off
- site evaluation activities no more than 1 time per 2 year period, the number of laboratories expected to complete off
- site evaluation activities were evenl y distributed over a 2 ye ar - period to estimate burden hours per ye ar (e.g., laboratories seeking c ertification , 45 laboratories/2 years = approximately 22.5 labs/ye ar). Burden hours associated with all States reviewing off
- site evaluation activities f or the laboratories applying for certification are estimated at 315 labor hours per year (Appendix K)
. States will conduct a 1 to 2 day on - site evaluation of each laboratory seeking State recognition of laboratory capability under the Lab QA Program . Th e burden hours associated with this task include time required to travel to and from the laboratory , conduct short briefings before and after the audit, observe the techniques (including independent count of a blind slide) for the methods for which the lab oratory is seeking certification, and participate in discussions with the laboratory

personnel
. Because laboratories will undergo an on
- site evaluation no more than 1 time every

2 years, the number of laboratories expected to be evaluated were evenl y distributed over a 2 ye ar period to estimate burden hours per ye ar (e.g., laboratories seeking c ertification , 45 laboratories/2 years = approximately 22.5 labs/ye ar). Burden hours for States conducting on
- site evaluations for laboratories applying for certification are estimated at 450 labor hours per ye ar (Appendix K). States integrating Cryptosporidium certification programs will track and review proficiency

test results (3 samples per set) 2 times a year for each method version for which the laboratory

is seeking certification. The burden estimates associated with this task include labor associated with receiving, documenting, tracking and reviewing each laboratory ’s PT results. Burden hours for States tracking and reviewing 1 set of proficiency test sample s 2 times a year are estimated at 135 labor hours per ye ar (Appendix K). It is estimated that 4 laboratories seeking State certification will perform more than 1 method version and will perform an additional set of PT samples for each additional method ver sion 2 times a year. Burden hours for States reviewing an additional set of PT samples for each additional method version are estimated at 12 labor hours per ye ar (Appendix K). EPA estimates that States will perform follow
- up activities with a small subset of laboratories seeking c ertification based on QA/QC deficiencies , failed OPRs, incomplete records, delayed communication to the state or PT results12

more than 2 standard deviations below the mean value of all participating labs . Burden hours for States coordinating these follow
- up activities are estimated at 21 labor hours per year (Appendix K). States will notify

laboratories of certification status after satisfactory completion of all activities. The burden hours associated with this task include time to produce an audit report noting any deficiencies, develop certificate s , document communication with the laboratory personnel , and maintain certified laboratory list on State website
. Because laboratories will be notified no mo re than 1 time every 2 years, the number of laboratories expected to be notified were evenl y distributed over a 2 ye ar period to estimate burden hours per ye ar (e.g., laboratories seeking certification , 45 laboratories/2 ye ars = approximately 22.5 labs/ye ar). Burden hours for States conducting the laboratory notifications and maintaining certified laboratory lists are estimated at 619 labor hours per ye ar (Appendix K). **6(b) Estimating Respondent Costs**  Below are s ummaries of respondent burden costs for this information collection. EPA consulted with fewer than nine respondents from the community of laboratories that have voluntarily

applied for EPA approval of laboratory capability

to perform Cryptosporidium anal ys es using EPA Method 1622 , 1623 , and 1623.1 and States integrating Cryptosporidium Certification Programs to obtain burden cost estimates. Respondent costs associated with anal ys is of PT samples include labor and O&M costs, which are estimated by the laboratories and include cost of anal ytical sample and PT set
. Respondent costs associated with evaluation activities include labor and O&M costs, which are estimated by the laboratories and include application fees and travel fees for auditors

- up activities with a small subset of laboratories seeking certification based on inadequate QA/QC, failed OPRs, incomplete records, delayed communication or PT results more than 2 standard deviations below the m ean value of all participating labs . Burden costs for State s conducting the coordination based on inadequate QA/QC, failed OPRs, incomplete records, delayed communication or poor PT results are estimated at $ 2,247.00 per year. Burden costs associated with this task include $ 2,247.00 for labor and $ 0.00 for O&M (Appendix K). Burden costs for all States notifying laboratories of certification status after satisfactory completion of all activities and maintaining a list of certified laboratories on state web site are estimated at $ 66,791.25 per year . Burden costs associated with this task include $ 66,791.25 for14

labor and $ 0.00 for O&M (Appendix K). **6(c) Estimating Agency Burden and Costs**  Below are Agency

burden hours and associated financial costs pertaining to implementation of the Lab QA Program. For a specific breakdown of burden hours and financial costs, refer to the Agency Annual Burden table in Appendix K . Costs and burden hours are broken out based on activities completed by the Agency

and supporting contractors. EPA estimates an average hourly cost of $ 87.25 /hour for Agency program management staff. Based on the published schedule of contractor labor rates for the years covered by this program, the average loaded burden hours and costs for contractor labor were estimated at $ 62.60 /hour for management staff, and $ 43.57 /hour for technical staff. Agency burden is estimated based on the labor hours associated with performing each tas k for each laboratory seeking State certification
. To get the total annual cost, hours and costs are then multiplied by

the estimated number of respondents and added to the capital and O&M costs. The burden associated with each information collection task is shown in a separate row of the burden table. EPA estimates that 45 laboratories will participate in the EPA L ab QA Program and 20 States will integrate Cryptosporidium Certification Program s . Twenty
- one states have Cryptosporidium laboratories within their state boundaries and 19 states responded positively to an industry

survey [ASDWA]. If needed, the Agency

will assist State Certification Officers with review of laboratory evaluation application packages. The Agency burden asso ciated with this review is estimated at 461 labor hours and a cost of $ 25,224.75 per ye ar. If needed, the Agency

will assist State Certification Officers with off
- site evaluation activities, including internet anal ys t evaluation , and positive control and ongoing precision and recovery (OPR) slide evaluation. The Agency burden associated with off
- site evaluation activities is estimated at 39 4 labor hours and a cost of $ 24,058.78 for labor and $ 1,775.00 for O&M per year . If needed, the Agency

will assist State Certification Officers with on
- site evaluation activities, including independent counts of blind slides by analy sts. The Agency

burden associated with on
- site evaluation activities is estimated at 416 labor hours and a cost of $ 28,178.10 per ye ar. If needed, the Agency

will assist State Certification Officers with interpretation of PT results. The Agency

burden associated with this activity is estimated at 506 labor hours and a cost of $ 36,030.60 per ye ar. The Agency will assist State Certification Officers with interpretation of PT results for additional method versions. The burden associated with this activity is estimated at 45 labor hours and a cost of $ 3,202.72 per ye ar. The Agency

will maintain a li st of links to S tate websites and/or certified laboratories on EPA’s website. The Agency burden associated with this technical support is estimated at 130 labor hours and a cost of $ 8,475.20 per ye ar .15

**6(d) Estimating the Respondent Universe and Total**  **Burden and Costs** The affected entities include public and private water testing laboratories , and public administrators of environmental protection programs . EPA estimates that 45 laboratories will seek certification , of which 15 are private and 30 are state or local government entities
. EPA estimates that 20 States will integrate Cryptosporidium into existing certification programs. The respondent total burden and cost are provided in the Total Respondent and Agency Burden t ables in Appendix K and are described in greater detail in Sections 6(a)
- 6(c). **6(e) Bottom Line Burden Hours and Cost Tables**  (i) Respondent Tall y Refer to the burden table in Appendix K titled, Total Respondent and Agency Burden , for a specific breakdown of the respondent costs. The Lab QA Program will affect approximately 65 respondents. The laboratory and State respondents will engage in 13 different tasks (refer to Section 4(b)(ii)) involving 5 , 472 labor hours and costing approximately $ 508,718.13 per ye ar for labor (Appendix K) . Respondents will invest $0.00 per year in capital/start
- up costs and $ 2 95 , 056 .67 per ye ar in O&M costs (Appendix K)
. (ii) Agency

Tally Refer to the burden table in Appendix K titled, Total Agency and Agency Burden , for a summary of Agency

costs. Six Agenc y t asks are associated with the Lab QA Program. These tasks will involve approximately 1 , 953 labor hours annually resulting in a cost of $ 123,395.15 per year for labor. The Agency will invest approximately $0.00 per year in capital/start
- up costs and $ 1,775.00 per ye ar in O&M costs. **6(f) Reasons for Change in Burden**  There is an increase of 629 hours in the total estimated respondent burden compared with the I CR currentl y approved by OMB. Changes in burden have occurred due to inflation, changes in the respondent universe, re
- evaluation of hours for tasks, re
- evaluatio n of O&M costs, and improved demonstration of capability. There is also new burden from states integrating Cryptosporidium into their existing certification programs, taking over this responsibility from the EPA
. **6(g) Burden Statement**  The annual reporting and recordkeeping burden for this collection is estimated to average 8 4.2 hours annuall y per respondent ( laboratory or State) (the combined total hours per ye ar for laboratories seeking certification and States integrating Cryptosporidium certification programs divided by

65 total respondents ). Burden means the total time, effort, or financial resources expended b y persons to16

generate, maintain, retain, or disclose or provide information to or for a Federal agency . This includes the time needed to review instructions; develop, acquire, install, and utilize technology and sy stems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing an d providing information; adjust the existing way s to comply with any previously

applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of infor mation; and transmit or otherwise disclose the information. An agency may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it display s a currently

For access to docket materials, please call (202) 260
- 3027 to schedule an appointment. **Section I: Laboratory Quality Assurance Evaluation Program for Analysis of Cryptosporidium**  **under the Safe Drinking Water Act** In September 2000, the Stage 2 Microbial and Disinfection By products Federal Advisory Committee (Committee) signed an Agreement in Principle (Agreement) (65 FR 83015, Dec. 29, 2000) (EPA, 2000) with consensus recommendations for two future drinking water regulations: the Long Term 2 Enhanced Surf ace Water Treatment Rule (LT2ESWTR) and the Stage 2 Disinfectants and Disinfection By products Rule. The LT2ESWTR is to address risk from microbial pathogens, specifically Cryptosporidium , and the Stage 2 DBPR is to address risk from disinfection by product s. The Committee recommended that the LT2ESWTR require public water s ys tems (PWSs) to monitor their source water for Cryptosporidium using EPA Method 1622 or EPA Method 1623. Additional Cryptosporidium treatment requirements for PWSs would be based on th e source water Cryptosporidium levels. EPA intends to take into account the Committee’s advice and recommendations embodied in the Agreement when developing the regulations. To support Cryptosporidium monitoring under the LT2ESWTR, the Committee Agreement recommended that “compliance schedules for the LT2ESWTR...be tied to the availability

of sufficient anal ytical capacity at approved laboratories for all large and medium
- size affected s ys tems to initiate Cryptosporidium and E.coli monitoring...”(65 FR 83 015, Dec. 29, 2000) (EPA, 2000). Further, the Agreement recommended that Cryptosporidium monitoring b y large and medium sy stems begin within six months following rule promulgation. Given the time necessary for EPA to approve a sufficient number of laboratories to assure adequate capacity for LT2ESWTR monitoring, EPAA
- 4

would need to begin laboratory evaluation prior to promulgation of the rule in order to accommodate such an implementation schedule. Another factor that warrants initiation of the Lab QA Program prior to promulgation of the LT2ESWTR is grandfathering of monitoring data. The Agreement recommends that s ys tems with “historical” Cryptosporidium data that are equivalent to data that would b e collected under the LT2ESWTR be afforded the opportunity to use those “historical” (grandfathered) data in lieu of collecting new data under LT2ESWTR. EPA intends to propose such grandfathering provisions in the L T2ESWTR. If EPA indicates that laborato ries meet the criteria in the Lab QA Program described today prior to finalizing the LT2ESWTR, systems could develop monitoring data prior to the LT2ESWTR in anticipation of using it as grandfathered data. EPA’s Office of Ground Water and Drinking Water p lans to request from OMB an emergency

clearance that would enable expeditious implementation of a voluntary Lab QA Program to support Cryptosporidium monitoring under the LT2ESWTR. As such, the Agency

could begin to evaluate laboratories that can reliably measure for Cryptosporidium using EPA Method 1622 and Method 1623. During the effective period of the emergency

clearance, EPA intends to submit to OMB for review and approval a final I CR in order to continue data collection for the Lab QA Program. As part of today ’s notice, EPA is inviting comment on the L ab QA Program. Under the Lab QA Program, EPA would evaluate labs on a case
- by
- case basis through evaluating their capacity and competency to reliably

measure for the occurrence of Cryptosporidium in surface water using EPA Method 1622 or EPA Method 1623. The intent of this notice is not to propose establishing the Lab QA Program through a rulemaking. Rather, the criteria described in section I .C. are intended to provide guidance to laboratories that are interested in participating in the Lab QA Program. EPA has not yet proposed rulemaking on use of such “historical” data nor on the methods themselves under the LT2ESWTR. As noted above, EPA intends to propose allowing s ys tems to use equivalent “historical” data in lieu of collecting new data. EPA anticipates the data generated b y labs which meet the evaluation criteria would be very high quality, thus increasing the likelihood that such data would warrant consideration as acceptable “grandfathered” data. However, lab evaluation would not guarantee that data generated will be acceptable as “grandfathered” data, nor would failure to meet evaluation criteria necessarily preclude use of “grandfathered” data. For these reasons, EPA is not establishing th e Lab QA Program through rulemaking, but rather as a discretionary

and voluntary

program under the Safe Drinking Water Act, section 1442 (42 USC 300j
- 1(a)). **A. What is the purpose of the laboratory quality assurance evaluation program?** The purpose of the Lab QA Program is to identify laboratories that can reliably measure for the occurrence of Cryptosporidium in surface water. Existing laboratory certification programs do not include Cryptosporidium anal ys is. This program is designed to assess and confi rm the capability of laboratories to perform Cryptosporidium anal ys es. The program will assess whether laboratories meet the recommended personnel and laboratory

criteria in today ’s notice. This evaluation program is voluntary for laboratories. In the LT2ESWTR, however, EPA intends to require s ys tems to useA
- 5

approved (or certified) laboratories when conducting Cryptosporidium monitoring under the LT2ESWTR. **B. Why has EPA selected Methods 1622 and 1623 as the basis for determining the data quality of l** 

**aboratories that measure for Cryptosporidium?** EPA Method 1622 and EPA Method 1623 were developed as improved alternatives to the ICR Protozoan Method (EPA, 1996). EPA validated Method 1622 for the determination of Cryptosporidium in ambient water in Augus t 1998 and distributed an interlaboratory

validated draft method in January 1999. In addition, EPA validated Method 1623 for the simultaneous determination of Cryptosporidium (and Giardia ) in ambient water in February 1999 and distributed a validated draf t method in April 1999. In April 2001, EPA revised and updated Method 1622 (EPA
- 821
- R
- 01
- 026) (EPA, 2001a) and Method 1623 (EPA
- 821
- R
- 01
- 025) (EPA, 2001b) based on the following: laboratory

feedback, the development of equivalent filters and antibodies fo r use with the methods, and method performance data generated during the ICR Supplemental Survey s (EPA, 2001e). The results of these studies are documented in the Method 1622 interlaboratory validation study

report (EPA
- 821
- R
- 01
- 027) (EPA, 2001c) and the M ethod 1623 interlaboratory validation study

report (EPA
- 821
- R
- 01
- 028) (EPA, 2001d). **C. What criteria should I use to determine if my laboratory should apply?** A laboratory

that is interested in participating in the Lab QA Program currently should be operating in accordance with its QA plan (developed b y the laboratory) for Cryptosporidium analy ses. In addition, an interested laboratory should demonstrate its capacity and competency to analyze Cryptosporidium using the following recommended criteria: **1.

ncorp I&ET, Inc. to request an application package. **E. If I demonstrate my laboratory’s capacity and competency according to the the personnel and laboratory criteria, what do I do next?**  After the laboratory

submits to EPA an application package including supporting documentation, EPA intends to conduct the following steps to complete the process: 1. Upon receipt of a complete package, EPA contacts the laboratory for follow
- up information and to schedule participation in the performance testing program. 2. EPA sends initial proficiency testing (IPT) samples to the laboratory (unless the laboratory has already successfully anal yz ed such samples under EPA‘s Protozoan PE program). IPTA
- 7

samples p ackets consist of eight spiked samples shipped to the laboratory within a standard matrix. 3. The laboratory

anal yz es IPT samples and submits data to EPA. 4. EPA conducts an on
- site evaluation and data audit. 5. The laboratory

anal yz es ongoing proficiency testing ( OPT ) samples three times per year and submits the data to EPA. OPT sample packets consist of three spiked samples shipped to the laboratory

within a standard matrix. 6. EPA contacts laboratories by letter within 60 day s of their lab oratory on - site evaluation to confirm whether the laboratory has demonstrated its capacity and competency for participation in the program. **F. My laboratory has already submitted initial demonstration of capability (IDC) and initial performance testing**  **(IPT) data as part of the EPA Protozoan Performance Evaluation (PE) Program. Do I have to perform this demonstration testing again?**  No. If a laboratory

currently participates in the EPA Protozoan PE Program and acceptable IDC and IPT data have already b een submitted (for the version of the method that the laboratory

will use to conduct Cryptosporidium analy ses), EPA would not expect the laboratory to repeat IDC and IPT analy ses. **Section II: Paperwork Reduction Act** The information collection requirements in this notice have been submitted for approval to the OMB under the Paperwork Reduction Act , 44 U.S.C. 3501 et seq . An I CR document has been prepared b y EPA (ICR No. 2052.02) and a copy may be obtained from Susan Auby b y mail at Collection Strategies Di vision; EPA (2822); 1200 Pennsylvania Ave., NW, Washington, DC 20460, by email at auby .susan@epamail.epa.gov, or by calling (202) 260
- 4901. A copy may also be downloaded off the internet at http://www.epa.gov/icr. Since the EPA would solicit information in application packages, including supporting documentation, anal ytical data, and other pertinent information from laboratories that are interested in participating in the voluntary L ab QA Program, the Agency is required to submit an ICR to OMB for review and approval. Entities potentially affected by

this action include public and private laboratories that wish to be evaluated to determine if they can reliably

measure for the occurrence of Cryptosporidium in surface waters that are used for drinking water sources using EPA Method 1622 or Method 1623. The burden estimate for the Lab QA Program information collection includes all the burden hours and costs required for gathering information, and developing and maintaining records associated with the Lab QA Program. The annual public reporting and recordkeeping burden for this collection of information is estimated for a total of 60 respondents and an average 78 hours per response for a total of 4,676 hours at a cost of $123,650. This estimate assumes that laboratories participating in the L ab QA program have the necessary equipment needed to conduct the analy ses. Therefore, there are no start
- up costs. The estimated total annual capital costs is $0.00. The estimated Operation and Maintenance (O&M) costs i s $133,880. Burden means the total time, effort, or financial resources expended b y persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and sy stems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing way s to comply with any previously

a pplicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collectionA
- 8

of information; and transmit or otherwise disclose the information. An Agency

may not con duct or sponsor, and a person is not required to respond to a collection of information unless it displays a currently valid OMB control number. The OMB control numbers for EPA's regulations are listed in 40 CFR Part 9 and 48 CFR Chapter 15. Comments are requested on the Agency's need for this information, the accuracy of the provided burden estimates, and any suggested methods for minimizing respondent burden, including through the use of automated collection techniques. Send comments on the I CR to the Director, Collection Strategies Division; EPA (2822); 1200 Pennsylvania Ave., NW, Washington, DC 20460; and to the Office of Information and Regulatory Affairs, Office of Management and Budget, 725 17th St., N.W., Washington, DC 20503, marked "Attention: Desk Officer for EPA." Include the ICR number in any correspondence. Because OMB is required to make a decision concerning the ICR between 30 and 60 day s after March 4, 2002, a comment to OMB is best assured of having its full effect if OMB receives it by April 3, 2002. The final ICR approval notice will respond to any OMB or public comments on the information collection requirements contained in today ’s notice. **References** EPA. 1996.

Quality Assurance Evaluation Program for Anal ys is of Cryptosporidium under the Safe Drinking Water Act (OMB Control No. 2040
- 0246 ; EPA ICR No. 2067.01 ) expiring 7/31/02 . This is a request for extension of a currentl y approved collection. Abstract: Section I: Laboratory Quality Assurance Evaluation Program for Analysis of Cryptosporidium Under the Safe Drinking Water Act In September 2000, the Stage 2 Microbial and Disinfection By products Federal Advisory Commi ttee (Committee) signed an Agreement in Principle (Agreement) (65 FR 83015, Dec. 29, 2000) (EPA, 2000) with consensus recommendations for two future drinking water regulations: The Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) and the Stage 2 Disinfectants and Disinfection By products Rule. The LT2ESWTR is to address risk from microbial pathogens, specificall y Cryptosporidium , and the Stage 2 DBPR is to address risk from disinfection by

products. The Committee recommended that the LT2ESWTR require public water sy stems (PWSs) to monitor their source water for Cryptosporidium using EPA Method 1622 orB
- 3

EPA Method 1623. Additional Cryptosporidium treatment requirements for PWSs would be based on the source water Cryptosporidium levels. To support Cry ptosporidium monitoring under the LT2ESWTR, the Committee Agreement recommended that ``compliance schedules for the LT2ESWTR * * * be tied to the availability of sufficient anal ytical capacity at approved laboratories for all large and medium
- size affected sy stems to initiate Cryptosporidium and E.coli monitoring * * * '' (65 FR 83015, Dec. 29, 2000) (EPA, 2000). Further, the Agreement recommended that Cryptosporidium monitoring by large and medium s ys tems begin within six months following rule promulgation . Given the time necessary for EPA to approve a sufficient number of laboratories to assure adequate capacity for LT2ESWTR monitoring, EPA would need to begin laboratory

evaluation prior to promulgation of the rule in order to accommodate such an implement ation schedule. Another factor that warrants initiation of the Lab QA Program prior to promulgation of the LT2ESWTR is grandfathering of monitoring data. The Agreement recommends that s ys tems with ``historical'' Cryptosporidium data that are equivalent to data that would be collected under the LT2ESWTR be afforded the opportunity to use those ``historical'' (grandfathered) data in lieu of collecting new data under LT2ESWTR. EPA intends to propose such grandfathering provisions in the LT2ESWTR. If EPA indicates that laboratories meet the criteria in the Lab QA Program described today prior to finalizing the L T2ESWTR, systems could develop monitoring data prior to the LT2ESWTR in anticipation of using it as grandfathered data. Under the Lab QA Program, EPA would evaluate labs’ capacity and competency

to reliably

measure for the occurrence of Cryptosporidium in surface water using EPA Method 1622 or EPA Method 1623. The intent of this notice is not to propose establishing the Lab QA Program through a rulemaking. Rather, the criteria described in section I.C. are intended to provide guidance to laboratories that are interested in participating in the Lab QA Program. EPA anticipates the data generated b y l abs which meet the evaluation criteria would be very high qu ality , thus increasing the likelihood that such data would warrant consideration as acceptable ``grandfathered'' data. However, lab evaluation would not guarantee that data generated will be acceptable as ``grandfathered'' data, nor would failure to meet evaluation criteria necessarily

preclude use of ``grandfathered'' data. For these reasons, EPA is not establishing the Lab QA Program through rulemaking, but rather as a discretionary and voluntary program under the Safe Drinking Water Act, section 1442 (42 USC 300j
- 1(a)). **A. What Is the Purpose of the Laboratory Quality Assurance Evaluation Program?** The purpose of the Lab QA Program is to identify laboratories that can reliably measure for the occurrence of Cryptosporidium in surface water. Existing laboratory certification programs do not include Cry ptosporidium anal ys is. This program is designed to assess and confirm the capability

of laboratories to perform Cry ptosporidium anal ys es. The program will assess whether laboratories meet the recommended personn el and laboratory criteria in today's notice. This evaluation program is voluntary for laboratories. In the LT2ESWTR, however, EPA intends to require s ys tems to use approved (or certified) laboratories when conducting Cryptosporidium monitoring under the L T2ESWTR. **B. How Can I Obtain an Application Package?** After the OMB clearance described above, EPA plans to make applications available on EPA's website at www.epa.gov/safewater/ cry ptolabapproval.html. Completed applications should be sent to: EPA's L aboratory Quality Assurance Evaluation Program Coordinator, c/o Dy nCorp, 6101 Stevenson Avenue, Alexandria, VA 22304
- 3540. If a laboratory does not have access to the Internet, the laboratory may contact Dy

nCorp to request an application package. Applicati ons may

be submitted at any

time.B
- 4

**C. If I Demonstrate My Laboratory's Capacity and Competency According to the Personnel and Laboratory Criteria, What Happens Next?**  After the laboratory

submits to EPA an application package including supporting documentation, EPA intends to conduct the following steps to complete the process: 1) Upon receipt of a complete package, EPA contacts the laboratory for follow
- up information and to schedule participation in the performance testing program. 2) EPA sends initial proficiency testing (IPT) samples to the laboratory . IPT samples packets consist of eight spiked samples shipped to the laboratory within a standard matrix. 3) The laboratory

analyzes the IPT samples and submits data to EPA. EPA intends to have the laboratory ’s IPT data meet the IPT criteria of greater than 10% mean recovery and less than 71% relative standard deviation (these criteria were developed based on results from the first six rounds of the EPA PE program). This approach will be used unless unforeseen circumstances merit a reassessment of the approach. 4) EPA conducts an on
- site evaluation and data audit. Checklist for evaluation and audit is included in I CR. 5) The laboratory

analyzes ongoing proficiency testing (OPT) samples three times per year and submits the data to EPA. OPT sample packets consist of three spiked samples shipped to the laboratory

within a standard matrix. The results of the laboratory ’s OPT data must meet the OPT criteria which will be calculated for each round of OPT testin g using onl y the data from that round. EPA intends to calculate the lower limit as less than 2 standard deviations from the pooled mean using log it transformed data and intends to calculate the maximum RSD as 2 times the pooled RSD. This approach will be used unless unforeseen circumstances merit a reassessment of the approach. 6) EPA contacts laboratories by letter within 60 day s of their laboratory on - site evaluation to confirm whether the laboratory has demonstrated its capacity and competency for participation in the program. An agency

may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The OMB control numbers for EPA's regulations are listed in 40 CFR part 9 and 48 CFR Chapter 15. The Federal Register document required under 5 CFR 1320.8(d), soliciting comments on this collection of information was published on March 4, 2002 ( FR ). Three comments were received. Comments requested further information on the details of the Lab Quality Assurance Program. In response, EPA has added supplementary information to the ICR, including the program application, which includes the self
- audit checklist detailing the items that will be evaluated during the on
- site evaluation. EPA also has also developed a webpage to provide further information on the program. The website can be accessed at http://www.epa.gov/safewater/lt2/cla_final.html. Commenters expressed concern that the Lab QA Program does not address the Agency ’s obligation under the FACA Agreement in Principle to identify adequate laboratory

capacity to implement LT2ESWTR. The Lab QA Program does assess laboratory capacity through questions on the application on current and potential laboratory capacity to anal yz e Cryptosporidium samples and the on site evaluations. This information will be compiled as laboratory applications are received, and will be updated during on
- site evaluations. The on
- site evaluation will allow EP A to validate lab capacity reported to EPA.B
- 5

Comments were received on the burden estimates. Because laboratories that wish to begin using EPA Methods 1622 and 1623 are required by the methods to purchase the equipment necessary to demonstrate initial acceptable performance, and because this is a method requirement, rather than a program requirement (laboratories can perform the methods without ever participating in the program), the burden estimates assume that no capital costs will be incurred b y laborato ries participating in the program over and above the costs that would be incurred simply

to use the method. Because the program application requires the laboratories applying for approval under the program to submit initial performance data, laboratories that meet these requirements should already have the capacity to perform Methods 1622 or 1623 and therefore will not incur start
- up costs. Commenters wanted to know if training would be available for labs needing help. EPA will provide limited training to l aboratories needing assistance with the performance of Methods 1622 and 1623. Information on training will be posted on EPA’s website as it becomes available. Commenters wanted to know the earliest date that acceptable grandfathered data could be generate d. EPA is aware of the issues regarding grandfathered data acceptability and will address these issues in the proposed LT2ESWTR. These issues are outside of the scope of this I CR. Burden Statement: The annual public reporting and record keeping burden for this collection of information is estimated to average 18 hours per response. Burden means the total time, effort, or financial resources expended b y persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency
. This includes the time needed to review instructions; develop, acquire, install, and utilize technology and sy stems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing ways to comply with any previously

applicable instructions and requirements; train personnel to be able to respond to a collection of information; search data sources; complete and review the collection of information; and transmit or otherwise disclose the information. Respondents/Affected Entities: Testing Laboratories Estimated Number of Respondents: 60. Frequency of Response: 3 times per year. Estimated Total Annual Hour Burden: 4347 hours. Estimated Total Annualized Cap ital, O&M Cost Burden: $123,380. Send comments on the Agency's need for this information, the accuracy of the provided burden estimates, and any suggested methods for minimizing respondent burden, including through the use of automated collection technique s to the addresses listed above.

Title: Laboratory Quality Assurance Evaluation Program for Anal ys is of Cry ptosporidium under the Safe Drinking Water Act. Abstract: Under the Laboratory Quality Assurance Evaluation Program, EPA evaluates labs on a case
- by
- case basis through evaluating their c apacity and competency to reliabl y measure for the occurrence of Cry ptosporidium in surface water using EPA Method 1622 or EPA Method 1623. To obtain approval under the program, the laboratory must submit an application package and provide: a demonstration of availability of qualified personnel and appropriate instrumentation, equipment and supplies; a detailed laboratory standard operating procedure for each version of the method that the laboratory will use to conduct the Cry ptosporidium anal ys es; a current copy of the table of contents of their laboratory ’s quality assurance plan for protozoa anal ys es; and an initial demonstration of capability data for EPA Method 1622 or EPA Method 1623, which include precision and recovery test results and matrix spike/matrix spike duplicate test results for Cry ptosporidium. After the laboratory submits to EPA an application package including supporting documentation, EPA and the laboratory conduct the following steps to complete the process: 1. EPA contacts the laborat ory for follow
- up information and to schedule participation in the performance testing program. 2. EPA sends initial proficiency testing samples to the laboratory (unless the laboratory has already successfully anal yz ed such samples under EPA’s Protozoan PE program). These sample packets consist of eight spiked samples shipped to the laboratory within a standard matrix. 3. The laboratory

anal yz es initial proficiency testing samples and submits data to EPA. 4. EPA conducts an on
- site evaluation and data a udit. 5. The laboratory

anal yz es ongoing proficiency testing samples three times per year and submits the data to EPA. These sample packets consist of three spiked samples shipped to the laboratory

within a standard matrix. 6. EPA contacts laboratories b y l etter within 60 day s of their laboratory onsite evaluation to confirm whether the laboratory has demonstrated its capacity and competency for participation in the program. The procedure for obtaining an application package, the criteria for demonstratin g capacity and competency , and other guidance to laboratories that are interested in participating in the program, are provided at http://www.epa.gov/ safewater/lt2/cla_final.html. An agency

may not conduct or sponsor, and a person is not required to respond to, a collection of information unless it displays a currently valid OMB control number. The OMB control numbers for EPA’s regulations in 40 CFR are listed in 40 CFR part 9 and are identified on the form and/or instrument, if applicable. Burden Statement: The annual public reporting and recordkeeping burden for this collection of information is estimated to average 19 hours per response. Burden means the total time, effort, or financial resources expended b y persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency . This includes the time needed to review instructions; develop, acquire, install, and utilize technology and s ys tems for the purposes of collecting, validating, and verifying information, processing and maintaining information, and disclosing and providing information; adjust the existing way s to compl y with any previouslyC

Quality Assurance Evaluation Program for Anal ys is of Cryptosporidium under the Safe Drinking Water Act (Renewal). ICR numbers: EPA ICR No. 2067.04, OMB Control No. 2040
- 0246. ICR status: This I CR is currentl y scheduled to expire on May 31, 2009. An Agency

may not conduct or sponsor, and a person is not required to respon d to, a collection of information, unless it displays a currently valid OMB control number. Approved OMB control numbers for EPA's regulations in title 40 of the CFR are listed in 40 CFR part 9 of the Federal Register and displayed either by

publication of the Federal Register or by other appropriate means, such as on the applicable collection instrument or form. Abstract: In September 2000, the Stage 2 Microbial and Disinfection By products Federal Advisory Committee (Committee) signed an Agreement in Prin ciple (Agreement) (65 FR 83015, December 29, 2000) (EPA, 2000) with consensus recommendations for two future drinking water regulations: the Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) and the Stage 2 Disinfectants and Disinfection By produ cts Rule. The LT2ESWTR was to address risk from microbial pathogens, specifically Cryptosporidium . The Committee recommended that the LT2ESWTR require public water s ys tems (PWSs) to monitor their source water for Cryptosporidium using EPA Method 1622 or EP A Method 1623. Additional Cryptosporidium treatment requirements for PWSs would be based on the source water Cryptosporidium levels. EPA took into account the Committee's advice and recommendations as it developed the LT2ESWTR, which was published on January 5, 2006. Under the LT2ESWTR, EPA requires public water s ys tems to use approved laboratories when conducting Cryptosporidium monitoring. In the preamble to the LT2ESWTR as well as several other notices, EPA has described the criteria for approval of lab oratories to anal yz e Cryptosporidium samples under the LT2ESWTR. See 71 FR 727 (January 5, 2006) and 67 FR 9731 (March 4, 2002). The Lab QA Program, as revised, is described in this notice. The purpose of the Lab QA Program is to identify laboratories that can reliabl y measure for the occurrence of Cryptosporidium in surface water and to ensure that approved laboratories maintain that capability . Other, State
- based laboratory oversight programs do not currently address approval of laboratories for the Cryp tosporidium analy sis required by the LT2ESWTR.D

Through today's notice, EPA is inviting comment on refinements to the information collected to support EPA's L ab QA Program. As of May 2007, EPA concluded that sufficient laboratory

capacity exists for the LT 2ESWTR. As a result, EPA has generally postponed evaluation of additional laboratories, including commercial, county, municipal and utility laboratories, until further notice. Subject to the availability of resources, EPA will consider evaluation of State and EPA Regional laboratories on a case
- by
- case basis, based on the role that States and EPA Regions play in the certification and approval programs for laboratories. The Lab QA Program is continuously being refined and updated as new information and techn ologies become available. The program will continue to evolve and EPA will continue to revise and update burden estimates, as needed, with any subsequent ICR. Approved laboratories will have demonstrated, and are to continue to demonstrate, proficient and reliable detection and enumeration of Cryptosporidium in surface water sources for public water s ys tems. They will have passed all elements in the Lab QA Program and continue to successfull y participate in all program activities. Approved laboratories are responsible for notifying EPA of losses of key personnel or essential equipment and changes in policies or procedures that directl y affect the validity of data or any other change affecting the capability of the laboratory

including change in location. Participating laboratories are to also demonstrate ongoing capability and method performance b y following all applicable method quality control (QC) procedures, anal yz ing ongoing proficiency testing (PT) samples (generall y three times per ye ar), submitting requested data to EPA, and participating in periodic re
evaluations. The Lab QA Program procedures have been updated to reflect that the minimum recovery for Cryptosporidium in ongoing precision and recovery (OPR) samples is no w 22 percent, updated from th e original 11 percent. This updated minimum recovery is based on an updated data set and should provide a better assessment of laboratory performance than the original value for the following reasons: (1) The data set is more current and is based on more s amples (a total of 333); (2) 52 more laboratories are included in the data set; (3) data were generated using the 2005 version of Method 1623, which is the required version for LT2ESWTR anal ys es; (4) data were generated using filters currently used to anal yz e LT2ESWTR samples rather than those filters used originally ; and (5) the number of oocy sts spiked into the samples was unknown to the laboratories. Calculations for the updated criteria are available in Docket ID No. EPA
- HQ
- OW
- 2002
- 0011. L aboratories are to now document a minimum of 22 percent recovery for OPR samples in an updated QC chart prior to anal ys is of LT2ESWTR samples at the frequency

required in section 9.7 of the method. The ongoing PT sample packets generall y consist of three spiked samples shipped to the laboratory

within a standard matrix. I f a laboratory submits poor PT results, EPA may recommend additional follow
- up action to demonstrate that the laboratory's performance remains acceptable. Additional actions may include submission of PT slides to EPA, repeat anal ys es, providing additional QC data, and investigation of proble ms with reagents and equipment. Repeated failure to demonstrate laboratory capability

and acceptable method performance may result in suspension or downgrading of app roval status as outlined later in this section. EPA may re - evaluate laboratories participating in the program to verify Cryptosporidium laboratory

quality assurance (QA) on both an ``as
- needed'' and periodic basis (generall y not exceeding once every

three ye ars). In the case of a periodic assessment, EPA will generall y notify the laboratory

that they are due for re
- evaluation and request a package with documentation of personnel status, equipment maintenance, standard operating procedures, training records , and QC charts. After the package has been received, it will be evaluated forD
- 6

completeness. EPA generally contacts the laboratory

within 15 day s of package submission if information is missing. When a complete package has been received, the following step s will complete the process: 1. The laboratory

will send positive staining control and OPR slides for evaluation by EPA. 2. The laboratory

will order blind slides spiked with Cryptosporidium from a qualified vendor for each anal ys t. Each analy st will p erform an independent count of one slide. The results and slides will be submitted to a technical auditor. 3. EPA will schedule an on
- line Internet anal ys t verification of performance for microscopists to demonstrate their ability to identify Cryptosporidium oocysts. 4. EPA conducts a one
- day on - site evaluation that will primarily focus on method performance and data recording. Laboratory personnel will be asked to order blind oocy st suspensions for use in sample and IMS control spiking in the presence of an auditor, and then complete the anal ys es within applicable method holding times and send results to EPA. 5. EPA will send the laboratory a report detailing all findings, generally within 60 day s after the evaluation is complete. The laboratory is then asked to provide written responses to any deficiencies identified in the report within 60 day s. Provided all responses to the deficiencies cited in the report are acceptable, the Lab QA Program will then base its decision for continued laboratory

approval on PT results, quality of the positive control and OPR slide, slide counts, Internet anal ys t verification, on
- site evaluation and recovery values for blind anal ys es initiated during the on
- site evaluation. State and EPA Regional Laboratories may contact the laboratory

approval manager regarding new application submissions. Subject to available resources, EPA estimates that up to two State or EPA Regional Laboratories will seek first
- time approval each year. Laboratories seeking approval under the program must submit an application package and provide: a demonstration of availability of qualified personnel and appropriate instrumentation, equipment and supplies; detailed laboratory standard operating procedures; a current copy of the table of contents of th eir laboratory's QA plan for protozoa anal ys es; and an initial demonstration of capability data for EPA Method 1623, which includes initial precision and recovery IPR test results and matrix spike/matrix spike duplicate (MS/MSD) test results for Cryptosporidium
. After EPA completes its review of the application, the Agency will contact the laboratory for follow
- up information and to schedule shipment of initial PT samples consisting of eight spiked samples within a standard matrix. EPA then generally conduc ts an on - site evaluation and data audit. Further information is provided at http://www.epa.gov/safewater/disinfection/lt2/lab_home.html. The Agency notes that completion of an application b y a laboratory does not ensure that the Agency will act on the labo ratory's request; interested laboratories are encouraged to contact the laboratory approval manager prior to investing substantial effort towards their application. Further, a decision by the Agency

to review an application, to send initial PT samples, and /or to schedule or conduct an on
- site evaluation and data evaluation, does not ensure that the review process will be completed or that the laboratory

will ultimately

be approved. Decisions will be made based on the facts associated with a particular appli cation and actions will be taken as Agency resources permit. Approved laboratories that do not continue to meet the criteria for the Lab QA Program may have their status downgraded to provisional or have their approval suspended. Details of the basis for downgrading or suspending a laboratory's approval are provided in the section entitled ``Clarification of Basis and Procedures for Downgrading/Suspending Approval for Laboratories for the Anal ys is of Cryptosporidium in Water Under the Long Term 2 Enhanced Surface WaterD
- 7

Treatment Rule'' (see the following section). Provided EPA has sufficient resources to review requests for upgrade or reinstatement, laboratories may have to undertake additional activities such as anal yz ing additional PT samples, undergoing an on - site evaluation, and/or counting blind spiked slides in order to have their status upgraded or their approval reinstated. Details regarding additional activities that may be required are provided in the next section. Clarification of Basis and Proce dures for Downgrading/Suspending Approval of Laboratories for the Anal ys is of Cryptosporidium in Water Under the L on g Term 2 Enhanced Surface Water Treatment Rule EPA's Office of Ground Water and Drinking Water, in the Office of Water, has developed a de tailed description of the procedures and criteria used in actions concerning approving, downgrading and suspending laboratories for anal ys is of drinking water contaminants. In order to assume primary enforcement responsibility for the drinking water regulations, a State must either have available laboratory facilities, approved by

the Administrator, capable of conducting anal ytical measurements of drinking water contaminants, or establish and maintain its own program for approval of laboratories. Stat es wishing to adapt these procedures and criteria for their own approval program should revise it to accuratel y reflect their State approval program. This section is intended to clarify EPA's intended practices and procedures for laboratory approval, down grading or suspension for analy sis of Cryptosporidium under the Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) and to reflect good laboratory practice and standard proficiency

evaluation in the industry; it is not a regulation. While EPA intends to generall y follow the procedures laid out in this section, not every situation is reflected in these procedures and EPA may need to address case
- specific situations in way s that differ from the procedures spelled out here. EPA welcomes comment on the se procedures and may decide to revise them at any time in the future to reflect changes to its approach or to clarify and update the text. ``Approved Laboratories'' have demonstrated, and continue to demonstrate, proficient and reliable detection and enumeration of Cryptosporidium in surface water sources for public water sy stems. They

have passed all elements in the Lab QA Program and continue to successfull y participate in all program activities. Approved Laboratories notify the Approval Authority

(EPA individual(s) administering the program or State individual(s) administering an equivalent laboratory

certification program) of loss of key personnel or essential equipment, change in policies or procedures that directl y affect the validity of data, and any other change affecting the capability of the laboratory

including change in location. ``P rovisionally

Approved L aboratories'' have deficiencies but demonstrate their ability to consistently

produce data of known quality . They continue to successfull y participate in all Lab QA Program activities. A Provisionally Approved Laboratory

may anal y ze drinking water samples for LT2ESWTR compliance purposes if the laboratory has identified themselves as provisionally

approved to their clients and any reports clearl y state that the laboratory's status is ``provisionally

approved.'' ``Not Approved'' d esignates a laboratory that has either not participated in the Lab QA Program, or has applied to the program but possesses deficiencies and, in the opinion of the Approval Authority, does not consistently produce data that has met all applicable method QC requirements or has falsified data.D
- 8

Basis for Downgrading to ``Provisionally Approved'' Status An Approved Laboratory (referred to as ``laboratory'') may be downgraded to ``P rovisionally

Approved'' status for Cryptosporidium for any of the following rea sons: Failure to anal yz e samples for the LT2ESWTR according to the December 2005 version of EPA Method 1623 or EPA Method 1622, including all QA/QC criteria; Failure to document a minimum of 22 percent for on
- going precision and recovery values in an upd ated QC chart prior to anal ys is of LT2ESWTR samples at the frequency required in section 9.7 of the method; Failure to demonstrate proficiency based upon acceptable matrix spike recoveries for all modifications of the method procedures per Section 9.1.2 o f the method; Failure to submit valid Proficiency Test (PT) results or meet PT acceptance limits described b y the Approval Authority for the first two initial testing events or two out of three regular testing events administered by a vendor authoriz ed by

the Approval Authority
. The acceptance limits are laboratory mean recovery

between 2 standard deviations (SD) of the mean recovery for all approved laboratories in a given test event. Rec overies below the mean recovery minus 2 SD will fail the PT tes t event. Recoveries higher than the mean recovery plus 2 SD trigger additional evaluation, which may include one or more of the following: (1) On
- site evaluation; (2) presence of a proctor when processing PT samples during the next test event; and/or (3) s ubmission of PT microscope slides to the Approval Authority before the expiration of holding time during the next test event; Failure to submit PT slides within three weeks of PT test event when requested by the Approval Authority; Failure to m aintain records of method modifications per section 9.1.2.2 of the method; Failure to notify

the Approval Authority

of loss of key

personnel or essential equipment, change in policies or procedures that directl y affect the validity of data, or other changes affecting the capability

of the laboratory

including change in location. Laboratory Approval does not automatically

survive such changes; the Approval Authority may request an on - site or off

site evaluation and/or further proof of compliance with all applicable method requirements; Failure to submit on
- site evaluation materials and any other requested information within the time period requested by the Approval Authority ; or Failure to participate satisfactoril y in the Approval Authority Lab QA Program and demonstrate proficiency

based upon: Sample and method holding time records; anal ys t verification skills; relative quality of positive staining control and on
- going precision recovery (OPR) slides; acceptable performance of QC checks, in cluding but not limited to blind slide counts; and acceptable precision and recovery values for all method variations. Procedures for Downgrading to ``Provisionall y Approved'' Status The Approval Authority

will notify

the laboratory director or own er of its intent to downgrade after becoming aware of the situation warranting downgrading; The laboratory

director should review the problems cited, and within 30 day s of receipt of the letter, send a letter to the Approval Authority specifying imme diate corrective actions that are being taken;D
- 9

The Approval Authority

will consider the adequacy of the response and notify the laboratory

in writing of its approval status, generally within 14 day s of receipt of the laboratory's response; After the Approval Authority notifies a laboratory, the Approval Authority will post status on the Web site list of laboratories and may schedule an on
- site evaluation of the laboratory ; The laboratory

should identify

and correct its problem(s) to the Approval Authority's satisfaction within 30 days of being notified of the downgrade or have approval status suspended; A Provisionally

Approved laboratory

may continue to anal yz e samples for compliance purposes, but must identify its status as Provisio nally Approved on any report; A laboratory

may request that the Approval Authority or State provide technical assistance to help identify and resolve any

problem; however, adequate performance is the laboratory's responsibility and Approval Authority assistance should not delay the downgrading procedure. Basis for Suspending Approval Status A laboratory

may be downgraded from Approved or Provisionally Approved status to ``Not Approved'' for any of the following reasons: Repeated verification that all applicable method QC requirements have been followed, when in fact they

have not all been met; Repeated failure to document acceptable OPR values prior to anal ys is of LT2ESWTR samples; Reporting PT data from another laboratory as its own; Falsification of data or other deceptive practices including false verification that data submitted to the Data Collection and Tracking S ystem (DCTS) was generated using approved methods and met all method QA/QC criteria; Refus al to participate in on
- site or off
- site evaluations conducted b y the Approval Authority
. Basis for Suspending Provisionally Approved Status Failure to provide a letter to the Approval Authority within 30 day s that adequately explains what immediat e corrective actions were taken; Failure to identify

and correct problems in response to downgrade within 30 day s; Failure to provide accurate OPR control charts to the Approval Authority; Failure to submit valid PT results for the next two consecutive authorized PT test events within the acceptance limits specified; Continued failure to use the anal ytical methodology specified in the regulations; Failure to correct deviations identified during an on
- site evaluation within 30 d ay s; or Failure to provide requested demonstration, materials and documentation within 30 day s, including: acceptable matrix spike recoveries for all method variations per section 9.1.2 of the method; bench sheets, examination forms or OPR charts for any samples requested; remote anal ys t verification; recent positive staining control and OPR microscope slides, one of each; and blind slide counts for each anal ys t.D
- 10

Procedures for Suspension The Approval Authority

will notify

the laboratory, in writing, of its intent to suspend approval. If the laboratory wishes to request reconsideration of this decision, it should submit such a request in writing to the Approval Authority within 30 day s of receipt of the notice of intent to suspend approval. The laboratory will generall y be downgraded immediately to ``provisional approval'' in the interim while the suspension is being considered. If no request for reconsideration is filed, approval will be suspended. The request for reconsideration should be supported with an explanation of the reasons for the challenge and should be signed b y a responsible official from the laboratory such as the president/owner for a commercial laboratory , the laboratory supervisor of a municipal laboratory , or the laboratory director for a State or Regional laboratory
. The Approval Authority

will make a decision and notify the laboratory

in writing, generall y within 30 days of receipt of the request for reconsideration. If the request is determined to be valid, the Approval Authority will take appropriate measures to reevaluate the facility and notify the laboratory , in writing, of its decision, generall y within 60 days of the reevaluation. Denial of the request will generall y result in suspension of the laborat ory's approval. Once approval is suspended, a public water s ys tem may not use the laboratory

to analyze source water samples for compliance with LT2ESWTR source water monitoring requirements. The laboratory

should notify

its clients that it is no longer approved and will not accept any more LT2ESWTR samples for anal ys is. Upgrading or Reinstatement of Approval Subject to the availability of resources, the Approval Authority will consider written requests from the laboratory to seek upgrading or reinst atement of approval. Requests should state the reasons why the laboratory should regain its approval status. The laboratory should demonstrate that all deficiencies have been corrected and successfull y complete two consecutive authorized PT test events within acceptance limits for Provisionally Approved laboratories or three consecutive authorized PT test events within acceptance limits for suspended laboratories. The authorized PT test events being described here are those submitted to all laboratories in the Lab QA Program, not special issue blind samples purchased independentl y from the vendor. The laboratory

should provide evidence why the reasons for downgrading or suspension are no longer applicable and explain its technical competence. Acceptable demo nstration of technical competence may

include an on
- site evaluation and/or any other measure the Approval Authority deems appropriate. The Approval Authority will consider compliance history, corrective actions implemented by

the laboratory , effectiveness of corrective actions, and professional judgment of the Approval Authority. Grievances Laboratories with grievances during the authorized PT events or regarding participation in the L ab QA Program should immediately contact the Program Manager at th e Approving Authority and try to remedy

the problem. When the laboratory feels they

have not gotten immediate or satisfactory results, they should contact the supervisor at the Approving Authority
. The management at the Approving Authority will work with the Program Manager to quickl yD
- 11

address grievances. A final decision for all grievances will be made generally within 30 day s of contacting the Approving Authority
. Request for Comment The EPA is soliciting comments on this notice to: 1. Evaluate whether the proposed collection of information is necessary for the proper performance of the functions of the Agency , including whether the information will have practical utility ; 2. Evaluate the accuracy

of the Agency's estimate of the burden of the proposed collection of information, including the validity of the methodology

and assumptions used; 3. Enhance the quality , utility, and clarity of the information to be collected; 4. Minimize the burden of the collection of information on tho se who are to respond, including through use of appropriate automated electronic, mechanical, or other technological collection techniques or other forms of information technology, e.g., permitting electronic submission of responses; and 5. Consider any

necessary

changes to the Lab QA Program. As an example, EPA is particularl y interested in comments from States regarding the potential for their laboratory programs to assume any/ all responsibility for the approval and oversight of LT2ESWTR laboratories , including comments on the appropriate timeframes for such. The Agency also welcomes comments regarding the appropriateness of turning to commercial PT providers as the source of PT samples for laboratories, in lieu of the PT program currentl y administere d by the Agency
. Burden Statement: The burden estimate for the Lab QA Program information collection includes all the burden hours and costs required for gathering information, and developing and maintaining records associated with the Lab QA Program. An estimated 65respondents will participate in an average of 4.4 responses per ye ar to include: anal ys is and reporting of PT samples three times per year, application for initial or re
- audit once every three years, off

- site re
evaluation activities once every three years, and on
- site evaluation once every three years. A small subset of laboratories will perform follow
- up activities based on inadequate QA/QC, failed OPRs, incomplete records, delayed communication t o EPA or poor PT results. A few laboratorie s perform more than one method version and will anal yz e an additional set of PT s amples three times per ye ar. The total annual public reporting and recordkeeping burden for this collection of information is estimated to be 4843 hours at a cost of $269,800. 40. The average hours and cost per response for the average of 4.4 responses per year are 16.9 hours and $943.36, respectivel y. These estimates assume that laboratories participating in the Lab QA Program have the necessary

equipment needed to conduct the analy ses. Therefore, there are no start
- up costs. The estimated total annual capital cost is $0.00. The total estimated Operation and Maintenance (O&M) costs is $141,929.00. The I CR provides a detailed explanation of the Agency's estimate, which is on ly briefly summarized here: Estimated Total Number of Potential Respondents: 65. Frequency

of Response: Annual. Estimated Total Average Number of Responses for Each Respondent: 4.4. Estimated Total Annual Burden Hours: 4843 hours.D
- 12

Estimated Total Annual Costs: $411,729.40. This includes an estimated burden cost of $269,800.40 and an estimated cost of $141,929.00 for capital investment or maintenance and operational costs. Are There Changes in the Estimates From the Last Approval? Changes in burden have occurred due to inflation, re
- evaluation of hours for tasks, and improved demonstration of capability. Inflation has increased all operation and maintenance and labor costs accordingl y. The increase in the respondent universe ha s increased the overall burden costs for the respondents. EPA's original estimates for hours to participate and maintain the Lab QA Program were made before the program began. Because the program has matured and several ye ars of QC data have been collected , the burden has changed for performing improved and refined procedures. The burden for some tasks has been estimated and will be re
- evaluated as the program progresses. EPA has added the preceding section entitled ``Clarification of Basis and Procedures for Downgrading/Suspending Approval for Laboratories for the Anal ys is of Cryptosporidium in Water Under the Long Term 2 Enhanced Surface Water Treatment Rule.'' Some approved laboratories may have to undertake additional activities to demonstrate continued acceptable performance to EPA, which may increase the burden of participation in the Lab QA Program for those laboratories. EPA estimates that nine laboratories per ye ar may have to undertake additional activities to demonstrate acceptable performance to EPA. These estimates will be corrected as the program continues. What is the Next Step in the Process for This ICR? EPA will consider the comments received and amend the ICR as appropriate. The final ICR package will then be submitted to OMB for rev iew and approval pursuant to 5 CFR 1320.12. At that time, EPA will issue another Federal Register notice pursuant to 5 CFR 1320.5(a)(1)(iv) to announce the submission of the I CR to OMB and the o pportunity to submit additional comments to OMB. If you have any questions about this I CR or the approval process, please contact the technical person listed under FOR FURTHER INFORMATION CONTACT. Dated: February

technology , e.g., permitting electronic submission of responses. EPA will consider the comments received and amend the ICR as appropriate. The final I CR package will then be submitted to OMB for review and approval. At that time, EPA will issue another Federal Register notice to announce the submission of the I CR to OMB and the opportunity to submit additional comments to OMB. Abstract: Under the Long Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR), EPA requires public water s ys tems to use approved laboratories when conducting Cry ptosporidium m onitoring. 40 CFR 141.705(a) provides for approval of Cry ptosporidium laboratories b y ``an equivalent'' State laborato ry certification program (i.e. e quivalent to EPA's Laboratory

Quality Assurance Evaluation Program). In the preamble to the LT2ESWTR, as w ell as several other notices, EPA has described the criteria for approval of laboratories to anal yz e Cry ptosporidium samples under the LT2ESWTR. See 74 FR 8529 (February 25, 2009), 71 FR 727 (January

5, 2006) and 67 FR 9731 (March 4, 2002). Through tod ay's notice, EPA is inviting comment on refinements to the information collected to support EPA's Lab QA Program. The procedures for Methods 1622, 1623, an d 1623.1 (a revision of Method 1623) have been updated to reflect that the minimum recovery for Cry pt osporidium in ongoing precision and recovery (OPR) samples is now 33 percent. This minimum recovery

is ba sed on an updated data set and should provide a better assessment of l aboratory

performance than the previous value for the following rea sons: (1) The data set is more recent; and (2) the sample size is more than twice as large as the 2009 sample size used to establish the previous value. State responsibilities for Cry ptosporidium laboratory

approval and oversight will be comparable to their certific ation responsibilities for the chemistry and microbiology

lab oratories that they oversee in their current programs (e.g., in itial evaluation of laboratory capability; ongoing assessment of the laboratory
-- including an assessment of Proficiency Test result s ; and on - site audits at least triennially). Whereas 40 CFR 14 2.10(b) generally requires the establishment and maintenance of a laboratory ``certification'' program for all regulated anal yt es, State approval programs for Cry ptosporidium laboratories are optional based on the structure of the LT2ESWTR (40 CFR 141.705(a)). If a laboratory

is located in a State that does not operate a Cry ptosporidium laboratory certification/accreditation program, that laboratory can still support L T2ESWTR mo nitoring ifE

the laboratory

has been approved by

another State's laborato ry certification/accreditation program that: (1) Has demonstrated substantial conformity to procedures described in Chapter 7 of ``Supplement 2 to the Fifth Edition of the Manual for the Certification of Laboratories Analyzing Drinking Water'' http://water.epa.gov/scitech/drinkingwater/labcert/index.cfm#two and (2) uses auditors that have passed the Te chnical Support Center's (TSC) Cry ptosporidium Laboratory

Certification Officers Training Course. PWSs should be aware that their States may e stablish requirements that are more stringent than EPA's regulations; State requirements would take precedence. Consistent with the longstanding la boratory certification program approach, TSC will: (1) Train State/Regional Certification Officers (CO) responsible for auditing Cry ptosporidium laboratories; (2) provide written guidance to State/Region al COs; (3) provide day
- to - day technical support to States, Regions , and laboratories; (4) review/ assist the Regional programs th at oversee State certification/ accreditation programs; and (5) maintain a list of l inks to State Web sites naming certified laboratories and/or a list of certified laboratories on EPA's Web site.

We have contacted 3rd party s that could approve us now, but the cost is over $4500. This will only serve to drive up our costs to our water department customers.

Quality Assurance Evaluation Program for Anal ys is of Cryptosporidium , etc. (EPA

- 0043) Dear Sir or Madam, The American Water Works Association (AWWA) appreciates the opportunity to comment on the U.S. Environmental Protection Agency ’s Information Collection Request, ‘‘Laboratory Quality Assurance Evaluation Program for Analy sis of Cryptosporidium Under the Saf e Drinking Water Act’’ (EPA I CR No. 2067.05, OMB Control No. 2040

–0246). Since 1991, the regulation of Cryptosporidium in drinking water has occurred through a collaborative partnership between the regulatory

community, drinking water suppliers and other s takeholders. AWWA has been deepl y involved throughout this period and was a party to the Microbial Disinfection By

product Federal Advisory Committee Agreement in Principle (M/DBP AIP) that underlies the Long
- Term 2 Enhanced Surface Water Treatment Rule (L T2ESWTR). AWWA’s members familiar with the LT2ESWTR, the ongoing Six
- Year Review of the LT2ESWTR, and laboratory

practices relevant to this I CR reviewed the proposed ICR. AWWA is committed to the effective implementation of LT2ESWTR and through these comments hopes to improve the LT2ESWTR laboratory

approval process so that water s ys tems can collect high quality data during Round 2 monitoring. April 24, 2012, EPA stated that it would announce if and how it would be revising the LT2ESWTR in December, 2014 (U.S. EPA, Regulatory Review Process for LT2 , Wy nne Miller, EPA Office of Ground Water and Drinking Water Standards and Risk Management Division, April 24, 2012). This date is important because in April 2015, water s ys tems must begin LT2ESWTR Round 2 moni toring. Since the April 2012 meeting EPA has not indicated to water sy stems whether LT2ESWTR Round 2 monitoring would indeed proceed. Given the lower than anticipated occurrence in Round 1, this is not a small question. At the April 2012 meeting and in rel ated stakeholder meetings, the drinking water community expressed a number of concerns that bear on this ICR and which the Agency should address, including:F
- 4

1) Affirm that Round 2 monitoring is needed and advise water s ys tems that Round 2 monitoring is proceeding as scheduled, or alternativel y if it is not proceeding. Notification is needed before December 31, 2013. 2) Advise water s ys tems subject to LT2ESWTR on the status and timeline for the current laboratory

approval process for Round 2 LT2ESWTR by no later than December 31, 2013 and provide a regularl y updated, centralized list of all approved labs and the states that approved each. 3) Remove recommendations for use of EPA Method 1623.1 from the authorized activities under this I CR until the method has b een robustly tested and the Agency

accounts for the method’s performance in a revised LT2ESWTR rule as was stipulated in the Microbial/Disinfection Byproduct Agreement in Principle. 4) Provide a centralized data management structure to collect Round 2 monito ring data and allow the laboratory

approval program to evaluate the ongoing performance of laborato ries during Round 2 monitoring (EPA has already discontinued support for the LT2ESWTR data sy stem used to support LT2ESWTR. Th ere is, at present, no plan to full y s upport LT2ESWTR Round 2 in SDWI S NextGen . See USEPA, SAFE Drinking Water Information Sy stem Next Generation, NextGen, Business Requirements Document, BRD, February 13, 2013). 5) In order to improve the benefits anal ys is for any future federal action s, provide states with guidance on how to incorporate genotyping into Round 2 monitoring. Incorporate a mechanism into implementation of Round 2 monitoring that facilitates collecting genotyping data from samples positive for Cryptosporidium
. 6) Correct the draft ICR in the following respects: a) Recognize that EPA has not modified the minimum recovery for Cryptosporidium in ongoing precision and recovery (OPR) samples to 33 percent in EPA Methods 1622 and 1623 (78 Federal Register 54644; 74 Federal Register 85 29 ; U.S. EPA, Method 1623: Cryptosporidium and Giardia in Water by Filtration/IMS/FA, December 2005, EPA 815
- R
- 05
- 002 , as referenced on EPA L aboratory Approval website on October 15, 2013, http://www.epa.gov/nerlcwww/documents/1623de05.pdf ). The Agency

has only included this new minimum recovery in EPA Method 1623.1 (U.S. EPA, Method 1623 .1 : Cryptosporidium and Giardia in Water by Filtration/IMS/FA, January 2012, EPA 816
- R
12
- 001, as referenced on EPA L aboratory Approval website on October 15, 2013, http://water.epa.gov/scitech/drinkingwater/labcert/upload/epa816r12001.pdf ). EPA cannot require use of EPA Method 1623.1 or change the ongoing precision and recovery (OPR) requirements for EPA Methods 1622 or 1623 without a rulemaking, which has yet to occur and for which there is inad equate time prior to laboratory approval for Round 2 monitoring. b) Expand the I CR cost analy sis to recognize the shifting of implementation burden for Round 2 laboratory

approval from EPA to state agencies, laboratorie s, and water s ys tems including:F
- 5

i) Confusion among regulators and laboratories about how the new s ys tem will work. ii) Lack of information upon which water sy stems can organize and budget procurement of laboratory

services from approp riatel y qualified laboratories. iii) In creased costs for the lab oratory approval process because of (1) the loss of federal subsidy , (2) inefficiencies in the new approach, and (3) additional fee structures i mposed by

certification bodies. Each of the above six points directly affect the final I CR and its associated i mplementation burden. These considerations will dramatically change the burden on states, laboratories, and sy stems associated with implementing this I CR over what was experienced during Round 1 monitoring. In addition to the above items, it is important that the Agency and the Office of Management and Budget be aware that additional dialogue with stakeholders is needed on how the Round 2 data will impact treatment requirements at affected facilities. The current rule language recognizes that Round 2 may

l ead to increasing or reducing treatment expectations. At EPA’s stakeholder meetings, staff acknowledged this framework, but it was also clear that additional dialogue is needed to describe how to utilize available data to make an informed treatment selecti on. If there is an opportunity

to assist EPA to distribute information to drinking water s ys tems so that they can begin procuring laboratory services for Round 2 monitoring, AWWA would be happy to assist the Agency . Similarly , AWWA looks forward to the earliest possible discussion of how Round 2 data should be incorporated into sound treatment selection processes under LT2ESWTR. Please do not hesitate to contact me or Steve Via at, (202) 326

**Method 1623 Ongoing Precision and Recover y (OPR) and Initial Precision and**  **Recovery (IPR) Quality Control Criteria Calculated from**  **Five Rounds of**

**Proficiency**

**Testing (PT)**  **Data Updated**  **July**

**9, 2013 Introduction**  The December 2005 Method 1623 Ongoing Precision and Recovery (OPR) and Initial Precision and Recovery

(IPR) quality

control and acceptance criteria were developed based on 293 Cryptosporidium OPR samples and 186 Giardia OPR samples analy zed by six laborato ries during the Information Collection Rule Supplemental Survey s from March 1999 to February 2000. In 2009, the minimum Cryptosporidium percent recovery for OPR samples was updated based on anal ys is of data from the February and May 2007 proficiency

testi ng (PT) rounds as published in the Federal Register ( Federal Register Notice, Vol. 74, No. 36 February 25, 2009 )
. To more accurately

reflect current laboratory capability

and provide better values for assessment of laboratory

performance, data from five PT rounds (February and May 2007, July

2009, February 2010, and March 2011) were used to develop quality control criteria. For each round, laboratories anal yz ed three blind reagent water samples spiked with flow
- cy tometer counted organisms prepared b y the Wisconsin State L aboratory of Hygiene. These updated criteria provide a better assessment of laboratory capability using Method 1623 than the 2009 values for the following reasons: 1) the data set is more recent; and 2) the sample size is more than twice as large as the 2009 sample size. A summary of the data set and proposed acceptance criteria are shown in Table 1. **Calculation of OPR Minimum Recovery Criteria**  The minimum Cryptosporidium percent recovery criteria for OPR samples were calculated based on data from the February and May 2007, July 2009, February

2010, and March 2011 PT rounds, which were all of the PT rounds with protozoan suspensions in reagent water without any additional matrix material. The remaining PT rounds had matrix additions and would not simulate an OPR or IPR. The acceptance criteria were calculated using data from labs approved and participating in the Lab QA Program as of June 24, 2011. The calculated lower l imit of recovery was 33% for Cryptosporidium and 29% for Giardia . When applying the criteria to the data from the five PT rounds, 51 samples or 6.8 % of the 753 samples did not meet the criteri on for Cryptosporidium , and 31 samples, or 5.8% of the 530 samp les, did not meet the criterion for Giardia
. **Details of the Calculation of OPR Minimum Recovery Criteria** To calculate OPR recovery criteria, estimates of variance attributable to four different sources were calculated: variability between laboratories, variability between PT rounds, variability between laboratory
- and
- round (i.e., attributable to an interaction between round and laboratory), and variability

within round and laboratory (i.e., analy

tical variability). There were a few laboratories that pe rformed PT anal ys es using multiple filters. For the purpose of these calculations, the two sets of anal ys es were two separate entities; in other words, the two lab/filter combinations were treated as two different laboratories. The different variance com ponents were calculated using PROC MIXED from SAS version 8 using the maximum likelihood method ofJ

estimation on recovery

data. Details on the maximum likelihood estimation can be found in SAS/STAT User’s Guide. 1 Estimates of between laboratory variance, between round variance, between laboratory
- and
round variance, and within laboratory
- and
- round variance were labeled s 2 L , s 2 R , s 2 LR and s 2 w , respectivel y. The combined standard deviation (s c ) is:

**Calculation of IPR Minimum Mean Recovery and Maximum RSD Criteria**  The QC acceptance criteria for IPR samples were calculated based on data from the February and May 2007, July

2009, February

2010, and March 2011 PT rounds. The calculated lower limit of recovery was 36% for Cryptosporidium and 32% for Giardia . When appl yi ng the criteria to the data from the five PT rounds, 16 (6.4%) of the 251 round/filter/laboratory combinations did not meet the criteri on for minimum mean recovery for Cryptosporidium , and 17 (7.1%) of the 240 combinations did not meet the minimum mean recovery criterion for Giardia . The maximum RSD of 34 % for Cryptosporidium and 37% for Giardia was also calculated using data from the five PT rounds. Applying the criteria to the data from all laboratories, 14 laboratory/ filter/round combinations (5.6%) did not meet the Cryptosporidium criterion and 14 combinations (5.8%) did not meet the Giardia criterion. Six of the 16 Cryptosporidium lab/round/filter combinations and 5 of the 17 Giardia combinations that failed the lower recovery

criterion also failed the precision criterion. It is worth noting that because the

criteria are calculated for 4 samples, while the data included onl y 3 ( Cryptosporidium ) or 2 ( Giardia ) results per lab, the failure rates would be expected to be greater than the target 5%. However, due to the large number of laboratory /filter/round combinations, the failure rate was ≈5%. **Details of the Calculation of IPR Criteria** Similar to the calculations for the OPR recovery criteria, IPR recovery

criteria were calculated with estimates o f variance attributable to four different sources: variability between laboratories, variability

between PT rounds, variability between laboratory
- and
- round (i.e., attributable to an interaction between round and laboratory), and variability within round and laboratory (i.e., anal ytical variability). There were a few laboratories that performed PT analy ses using multiple filters. For the purpose of these calculations, the two sets of anal ys es were two separate entities; in other words, the two lab/filter combinations were treated as two different laboratories. The different variance components were calculated using PROC MIXED from SAS version 8 using the maximum likelihood method of estimation on recovery data. Details on the maximum likelihood estimatio n can be found in SAS/STAT User’s Guide. 2 Estimates of between laboratory variance, between round variance, between laboratory
- and
round variance, and within laboratory
- and
- round variance were labeled s 2 L , s 2 R , s 2 LR and s 2 w , respectivel y. The combined stan dard deviation (s c ) is:
