(iii) FLUORIDE LEVEL ABOVE 2 MG/L AS SPECIFIED IN R 325.10408a.
(iv) AVAILABILITY OF UNREGULATED CONTAMINANT MONITORING DATA.
(v) OTHER VIOLATIONS AND SITUATIONS WHICH ARE DETERMINED BY THE DEPARTMENT TO REQUIRE A PUBLIC NOTICE UNDER THIS PART AND WHICH ARE NOT ALREADY LISTED IN TABLE 1 OF THIS RULE.
THE TIER ASSIGNMENT FOR EACH SPECIFIC VIOLATION OR SITUATION REQUIRING A PUBLIC NOTICE IS IDENTIFIED IN TABLE 1 OF THIS RULE.
(2) PUBLIC NOTICE REQUIREMENTS ARE DIVIDED INTO 3 TIERS TO TAKE INTO ACCOUNT THE SERIOUSNESS OF THE VIOLATION OR SITUATION AND OF THE POTENTIAL ADVERSE HEALTH EFFECTS THAT MAY BE INVOLVED. THE PUBLIC NOTICE REQUIREMENTS FOR EACH VIOLATION OR SITUATION LISTED IN SUBRULE (1) OF THIS RULE ARE DETERMINED BY THE TIER TO WHICH THE VIOLATION OR SITUATION IS ASSIGNED. THE DEFINITION OF EACH TIER IS PROVIDED IN THE FOLLOWING PROVISIONS:
(a) TIER 1 PUBLIC NOTICE IS REQUIRED FOR VIOLATIONS AND SITUATIONS THAT HAVE SIGNIFICANT POTENTIAL TO HAVE SERIOUS ADVERSE EFFECTS ON HUMAN HEALTH AS A RESULT OF SHORT-TERM EXPOSURE.
(b) TIER 2 PUBLIC NOTICE IS REQUIRED FOR ALL OTHER VIOLATIONS AND SITUATIONS THAT HAVE POTENTIAL TO HAVE SERIOUS ADVERSE EFFECTS ON HUMAN HEALTH.
(c) TIER 3 PUBLIC NOTICE IS REQUIRED FOR ALL OTHER VIOLATIONS AND SITUATIONS NOT INCLUDED IN TIER 1 AND TIER 2.
THE TIER ASSIGNMENT FOR EACH SPECIFIC VIOLATION OR SITUATION IS IDENTIFIED IN TABLE 1 OF THIS RULE.
(3) SUPPLIERS SHALL PROVIDE PUBLIC NOTICE TO THE FOLLOWING:
(a) EACH SUPPLIER SHALL PROVIDE PUBLIC NOTICE TO PERSONS SERVED BY THE SYSTEM AS SPECIFIED IN THIS PART. SUPPLIERS THAT SELL OR OTHERWISE PROVIDE DRINKING WATER TO OTHER PUBLIC WATER SYSTEMS, SUCH AS TO CONSECUTIVE SYSTEMS, SHALL
GIVE PUBLIC NOTICE TO THE SUPPLIER OF THE CONSECUTIVE SYSTEM; THE CONSECUTIVE SYSTEM IS RESPONSIBLE FOR PROVIDING PUBLIC NOTICE TO THE PERSONS IT SERVES.
(b) IF A PUBLIC WATER SYSTEM HAS A VIOLATION IN A PORTION OF THE DISTRIBUTION SYSTEM THAT IS PHYSICALLY OR HYDRAULICALLY ISOLATED FROM OTHER PARTS OF THE DISTRIBUTION SYSTEM, THE DEPARTMENT WILL GRANT PERMISSION, WHICH SHALL BE IN WRITING, TO THE SUPPLIER TO LIMIT DISTRIBUTION OF THE PUBLIC NOTICE TO ONLY PERSONS SERVED BY THAT PORTION OF THE SYSTEM WHICH IS OUT OF COMPLIANCE. TO BE PHYSICALLY SEPARATED, THE SUPPLIER SHALL SHOW THAT THE AFFECTED PORTION OF THE DISTRIBUTION SYSTEM IS SEPARATED FROM OTHER PARTS OF THE DISTRIBUTION SYSTEM WITH NO INTERCONNECTIONS. TO BE CONSIDERED HYDRAULICALLY SEPARATED, THE SUPPLIER SHALL SHOW THAT THE DESIGN OF THE DISTRIBUTION SYSTEM OR THE SYSTEM OPERATION, OR BOTH, CREATED A SITUATION WHERE WATER IN THE AFFECTED PORTION IS EFFECTIVELY ISOLATED FROM THE WATER IN ALL OTHER PARTS OF THE DISTRIBUTION SYSTEM BECAUSE OF PROJECTED WATER FLOW PATTERNS AND WATER PRESSURE ZONES.
(4) THE SUPPLIER, WITHIN 10 DAYS OF COMPLETING THE PUBLIC NOTIFICATION REQUIREMENTS UNDER THIS PART FOR THE INITIAL PUBLIC NOTICE AND APPLICABLE REPEAT NOTICES, SHALL SUBMIT TO THE DEPARTMENT A CERTIFICATION THAT IT FULLY COMPLIED WITH THE PUBLIC NOTIFICATION REGULATIONS. THE SUPPLIER SHALL INCLUDE WITH THIS CERTIFICATION A REPRESENTATIVE COPY OF EACH TYPE OF NOTICE DISTRIBUTED, PUBLISHED, POSTED, AND MADE AVAILABLE TO THE PERSONS SERVED BY THE SYSTEM AND TO THE MEDIA.

3 SYSTEMS WITH TREATMENT TECHNIQUE VIOLATIONS INVOLVING A SINGLE EXCEEDANCE OF A MAXIMUM TURBIDITY LIMIT UNDER R 325.10611b(1) ARE REQUIRED TO INITIATE CONSULTATION WITH THE DEPARTMENT WITHIN 24 HOURS AFTER LEARNING OF THE VIOLATION. BASED ON THIS CONSULTATION, THE DEPARTMENT MAY SUBSEQUENTLY DECIDE TO ELEVATE THE VIOLATION TO TIER 1. IF A SYSTEM IS UNABLE TO MAKE CONTACT WITH THE DEPARTMENT IN THE 24-HOUR PERIOD, THE VIOLATION IS AUTOMATICALLY ELEVATED TO TIER 1.
4 FAILURE TO TAKE A CONFIRMATION SAMPLE WITHIN 24 HOURS FOR NITRATE OR NITRITE AFTER AN INITIAL SAMPLE EXCEEDS THE MCL IS A TIER 1 VIOLATION. OTHER MONITORING VIOLATIONS FOR NITRATE ARE TIER 3.

7 FAILURE TO MONITOR FOR CHLORINE DIOXIDE AT THE ENTRANCE TO THE DISTRIBUTION SYSTEM THE DAY AFTER EXCEEDING THE MRDL AT THE ENTRANCE TO THE DISTRIBUTION SYSTEM IS A TIER 2 VIOLATION.
8 IF ANY DAILY SAMPLE TAKEN AT THE ENTRANCE TO THE DISTRIBUTION SYSTEM EXCEEDS THE MRDL FOR CHLORINE DIOXIDE AND 1 OR MORE SAMPLES TAKEN IN THE DISTRIBUTION SYSTEM THE NEXT DAY EXCEED THE MRDL, TIER 1 NOTIFICATION IS REQUIRED. FAILURE TO TAKE THE REQUIRED SAMPLES IN THE DISTRIBUTION SYSTEM AFTER THE MRDL IS EXCEEDED AT THE ENTRY POINT ALSO TRIGGERS TIER 1 NOTIFICATION.
9 WATERBORNE EMERGENCIES REQUIRE A TIER 1 PUBLIC NOTICE. THE DEPARTMENT MAY PLACE OTHER SITUATIONS IN ANY TIER IT BELIEVES APPROPRIATE, BASED ON THREAT TO PUBLIC HEALTH.

"THIS IS AN ALERT ABOUT YOUR DRINKING WATER AND A COSMETIC DENTAL PROBLEM THAT MIGHT AFFECT CHILDREN UNDER 9 YEARS OF AGE. AT LOW LEVELS, FLUORIDE CAN HELP PREVENT CAVITIES, BUT CHILDREN DRINKING WATER CONTAINING MORE THAN 2 MILLIGRAMS PER LITER (MG/L) OF FLUORIDE MAY DEVELOP COSMETIC DISCOLORATION OF THEIR PERMANENT TEETH (DENTAL FLUOROSIS). THE DRINKING WATER PROVIDED BY YOUR COMMUNITY WATER SYSTEM [NAME] HAS A FLUORIDE CONCENTRATION OF [INSERT VALUE] MG/L.
DENTAL FLUOROSIS, IN ITS MODERATE OR SEVERE FORMS, MAY RESULT IN A BROWN STAINING AND/OR PITTING OF THE PERMANENT TEETH. THIS PROBLEM OCCURS ONLY IN DEVELOPING TEETH, BEFORE THEY ERUPT FROM THE GUMS. CHILDREN UNDER 9 SHOULD BE PROVIDED WITH ALTERNATIVE SOURCES OF DRINKING WATER OR WATER THAT HAS BEEN TREATED TO REMOVE THE FLUORIDE TO AVOID THE POSSIBILITY OF STAINING AND PITTING OF THEIR PERMANENT TEETH. YOU MAY ALSO WANT TO CONTACT YOUR DENTIST ABOUT PROPER USE BY YOUNG CHILDREN OF FLUORIDE-CONTAINING PRODUCTS. OLDER CHILDREN AND ADULTS MAY SAFELY DRINK THE WATER.
DRINKING WATER CONTAINING MORE THAN 4 MG/L OF FLUORIDE (THE
U.S. ENVIRONMENTAL PROTECTION AGENCY'S DRINKING WATER STANDARD) CAN INCREASE YOUR RISK OF DEVELOPING BONE DISEASE. YOUR DRINKING WATER DOES NOT CONTAIN MORE THAN 4 MG/L OF FLUORIDE, BUT WE’RE REQUIRED TO NOTIFY YOU WHEN WE DISCOVER THAT THE FLUORIDE LEVELS IN YOUR DRINKING WATER EXCEED 2 MG/L BECAUSE OF THIS COSMETIC DENTAL PROBLEM.
FOR MORE INFORMATION, PLEASE CALL [NAME OF WATER SYSTEM CONTACT] OF [NAME OF COMMUNITY WATER SYSTEM] AT [PHONE NUMBER].
