An Overview

CERO - 7/29/2014

310CMR 22.00 - Regulation Update

• RTCR • Minor EPA Corrections to DBP and LT2 Rules

• Mainly numbering, typos etc• Certified Operator

• clarifies staffing requirements for the system versus individual facilities. • clarifies staffing requirements for systems with multiple treatment facilities.• adopts ABC’s new standards for the classification of treatment facilities,

which is the basis for examination and licensing for drinking water operators.

• Miscellaneous revisions include clarification of false reporting, new source approval issues, adding a definition for raw water, corrections of typos, re-incorporating the 2014 DWP Guidelines into the regulations, etc

310 CMR 27.00: Underground Injection Control Regulations (UIC) Updates

All changes are required by EPA to maintain PRIMACY for UIC

• Ban the installation of any new cesspool. • Removal of exemption of UIC Registration filing requirement for aquifer remediation

wells that were installed under the MCP regulations (310 CMR 40). • Adding Class V well types that are currently allowed in MA but are not included in

current version of regs.• References added to various UIC guidance documents.• Add authority to DEP to require a Groundwater Discharge Permit for a Class V well

as determined necessary by the Department (requested by EPA in 2004)• Add a well closure section.

310 CMR 46.00: Certification of Well Drillers Regulations Updates

An overall restructuring and rewrite of the text to make the regulations more readable and enforceable as well as reflective of current practices

Additions• New categories of Well Driller Certification

– Ground Source Heat Pump Installers (geothermal) – pump installers– Well Yield Enhancement

• Continuing Education requirements• Well Yield Enhancement provisions • DEP right of entry • Changing responsibility to obtain a permit for drilling rigs from the certified

driller to owner of the drilling rig (in some cases, this could be the certified driller)

Systems

1735 - PWS presently registered 521-COM systems 267-NTNC systems 947-TNC systems

Note: Another 54 PWS were active for only part of the year

Funding

Improving Public Health Protection through Risk Management

7

Since the 1996 Amendments, regulations now specifically address threats to the health of children and other sensitive sub-populations. Prior to 1996, these categories of individuals were incidentally protected based on the

single standard for all consumers.

SDWA Requirements

Health based water quality monitoring for 115 contaminants;Cross Connection Control; Underground Injection Control;Source Water Protection; Sanitary Surveys; Capacity Development; Lead and Copper Rule;

Total Coliform Rule;Ground Water Rule; Surface Water Treatment Rules; Filter Backwash Recycling Rule; Disinfectants and Disinfection By-Products Rule; Unregulated Contaminants Monitoring Rule;Public Notification;

Consumer Confidence Reporting; Operator Certification; New System Registration; Secondary Standards;Consecutive Systems; Metering, Point of Use/Point of Entry Treatment; Distribution Protection; and others.

2014 Additional Workload

9

• Revised Total Coliform Rule• Disinfection Byproducts Stage 2 Rule• Surface Water Treatment Rule Long Term 2• Unregulated Contaminant Monitoring Rules with emerging contaminants

• Water System capacity planning • Lead ban• Engineering review for treatment and innovative technology.•Manganese

Revised Total Coliform Rule (RTCR) By January 1, 2016 PWSs must comply with theRTCR requirements unless the state selects an

earlier implementation date.

10

• Applies to all PWSs. • Requires PWSs to perform assessments to identify sanitary defects and subsequently take action to correct them.

• Establishes a MCL for E. coli and • Uses E. coli and total coliforms to initiate a “find and fix” approach to address fecal contamination that could enter into the distribution system.

RTCR …Get Ready

–Familiarize yourself with Rule changes–Evaluate distribution system to

determine if current sample locations accurately reflect system–Perform mock Level 1 Assessment to

identify deficiencies–Educate local officials about upcoming

changes

11

Stage 2 Disinfectants/Disinfection Byproducts Rule (DBPR)

12

Continues Stage 1 DBPR: MCLs for THM, HAA5, Bromate and Chlorite; MRDLs for Chlorine,

Chloramines and Chlorine Dioxide; TT for Control of

Byproduct Precursors

Applies to COM and NTNC PWSs Including Consecutive

PWSs that Only Purchase Treated Water but

Compliance Dates and Requirements Vary Based on

Population, Source Water Type and Treatment

•Transition from Stage 1 to Stage 2 Staggered

•Final Transition Date was October 1, 2013MRDL for Chlorine Dioxide Applies to TNC PWSs that use Chlorine Dioxide

Stage 2 DBPR (Continued)

13

Long Term 2 Enhanced Surface Water Treatment Rule (LT2)

14

LT2 (Continued)

15

Unregulated Contaminant Monitoring Rule 3 (UCMR 3)

• Direct Implementation Rule– EPA Oversees Requirements with State Assistance

• Applies to All PWSs Serving >10,000 and a National Sample of PWSs Serving <=10,000

• 30 Contaminants– All PWSs Conduct Assessment Monitoring = 7 VOCs, 1 SOC, 6 Metals, 1

Oxyhalide Anion, 6 Perfluorinated Compounds– All PWSs Serving >100,000 and Selections of PWSs Serving <=100,000

Conduct Screening Survey = 7 Hormones– Selection of PWSs Serving <=1,000 Conduct Pre-Screen Testing = 2 Viruses

• 12 Months of Monitoring Staggered During 2013-2015• EPA Pays for Analysis of Samples from PWSs Serving <=10,000• EPA Collects Pre-Screen Viral Samples

16

UCMR 3 (Continued)• Used to Determine if Future Regulations are Needed• UCMR 3 Uses Lower Reporting Levels than Prior UCMRs

– Communication Challenge in that More Detections are Likely but Detections May Not Reflect Health Concerns

– EPA Guidance Puts Detections in Proper Context• October 2013 National Data Summary (Partial Results)

– Chlorate, 1,4-Dioxane and Vanadium Most Common Detects– Chlorate: 68% of PWSs Detected but only 25% of Detects Above EPA’s Draft

Reference Concentrations (i.e. Possible Health Concern)– 1,4-Dioxane: 19% of PWSs Detected but only 31% of Detects Above

Reference Concentration– Vanadium: 75% of PWSs Detected but only 4% of Detects Above Reference

Concentration• Results to be included in Consumer Confidence Reports

How are we going to get it all done?

• Public Health is our priority

Protection• Continue to

support & maintain current required programs

Programmatic• Promulgate and

implement new SDWA regulations

Regulations• Make sure all staff,

PWSs & certified operators have what they need

Training• SDWA Advisory

Committee• Partnering with

EPA & Others• Working with

PWS & Water Work Associations

• SDWA Assessment Committee

Work Together
