OPINION

AND ORDER

OF THE BOARD

(by G.

T. Girard):

On October 20,

1987, the Illinois Environmental Protection

Agency

(Agency)

filed a draft proposal to amend the cross-

connection control regulations.

The purpose of these proposed

amendments to the Pollution Control Board’s (Board) public water

supply regulations

(35 Ill. Adm. Code.Subpart F)

is to prevent

drinking water degradation by eliminating unprotected cross-

connections.

Cross—connections are actual or potential

connections between a potable and non—potable water supply.

Presently,

cross-connections are regulated by Section 607.104

(amended effective September 14,

1982).

The instant proposal

clarifies these regulations.

Section 607.104 would be repealed

concurrently with the final adoption of proposed Section 608.

PROCEDURAL

HISTORY

The instant rulemaking was filed pursuant to Sections

4 and

28 of the Environmental Protection Act (Act).

Addenda or

amendments to the original proposal were filed by the Agency on

October 27,

1987, May 17,

1988, October 11,

1988, and May 1,

1989.

Unless specified otherwise, references to the “Agency

proposal” in this document refer to the last amended proposal

filed by the Agency (May 1,

1989).

On March 26,

1992, the Board

invited public comment to update the record.

The record for making these regulations included several

public hearings, extensive public comments, and an Economic

Impact Study (EcIS).

Four public hearings on

the

proposal were

held by the Board: May 25,

1988 (Springfield); May 26,

1988

(Chicago); April 11,

1989 (Springfield);

and

May

1,

1989

(Chicago).

Ninety—one public comments were received by the Board

between April 4,

1988 and May 29, 1992

(listed in Appendix A).

On August 4,

1988 the Department of Energy and Natural Resources

(DENR) filed a letter with the Board that an Economic Impact

Study

(EcIS) would be undertaken.

EcIS hearings were held on

01 36~027$

---

2

June 26,

1990 in Springfield, and on June 28~ 1990 in Chicago

The DENR filed the EcIS on November 7,

1990.

Today the Board sends the proposal to first notice under the

Illinois Administrative Procedure Act

(IAPA)

(Ill. Rev.

Stat.

1991,

ch. 127,

par. 1001-let se~g.)

The Board’s action will

cause the publication of the proposal in the Illinois Register

and begin the minimum 45 day public comment period under the

IAPA.

The Board’s proposal is generally similar to the last

amended proposal filed by the Agency, but there are several

differences which are delineated in this opinion and order.

Also

by today’s action, the Board proposes to repeal the existing

cross-connection control regulations at 35 Ill. Adm.

Code

607.104

as the instant proposal (Part 608) will supersede Section

607. 104.

CROSS-CONNECTION

CONTROL

PROGRAM

Current Board regulations state that control of all cross—

connections to a public water supply is the responsibility of the

owner or official custodian of the supply

(35 Ill.

Adm.

Code

607

•

104

(C)).

The instant proposal clarifies the methods public

water supplies can use to accomplish that mandate.

Section

608.202 of the instant proposal requires the adoption of

ordinances or conditions of service which prohibit unprotected

cross—connections, specifies cross-connection control surveys of

the public water supply distribution system, and includes a

system for record keeping.

The proposal clearly states that the

public water supply will terminate service to any customer that

fails to comply (608.202(a)(4)).

In keeping with present

regulations

(Section 607.104(c)), the proposed regulations

(608.202(d)) place responsibility for control of all cross-

connections and interconnections on the owner or official

custodian of the water supply.

The investor owned water supplies represented by the

National Association of Water Companies and the Illinois—American

Water Company have presented extensive testimony and comments3

regarding the proposed cross—connection standards and have

suggested alternate requirements to address their concerns

(P.C.

12,

16, and 39).

In addition, the investor owned water supplies

group4 (IOWSG) has addressed the implications of the State

Mandates~Act

on

the ~propose&

cross~connection~contro1_program

requirements

(P.C.

38,

43,

52, and 53).

There has not been any

additional participation in this rulemaking by the public water

supplies owned by municipalities or local governments.

The Agency submitted several draft proposals to address the

concerns of the regulated community including the IOWSG.

A

discussion of the IOWSG’s concerns about the proposed cross-

connection control program requirements is presented below.

Program Reauirement Issues Raised by IOWSG

Ordinances and Conditions of Service.

The Agency proposal at

Section 608.202(a)

requires all public water supplies to adopt an

ordinance or condition of service which prohibits unprotected

cross—connections.

These ordinances or conditions of service

shall include at least one of the following:

a plumbing code as

stringent as the Illinois Plumbing Code (Section

608.202(a) (1) (A)); or a requirement that customers provide proof

that their plumbing is in accordance with a plumbing code as

stringent as the Illinois Plumbing Code (Section

608.202(a)

(1) (B));

or

installation

of cross—connection control

devices

at

all

service

connections,

except

for single family

dwellings

(Section

608.202

(a) (1) (C)).

In

addition

to

the

single family dwelling exemption, the

instant proposal at Section 608

•

202 (a)

(1)

(C)

sets

forth

two

additional exceptions to the proposed regulations.

Cross—

connection control devices would not be required at:

institutional, commercial,

or industrial establishments with only

drinking

water

fountains,

restrooms,

and

kitchen

facilities

(Section

608.302(b)); or multi—family residential dwellings

(Section 608.307).

The Agency proposal did not include the exemption provided

to certain institutional, commercial or industrial establishments

under the third “conditions of service” option at Section

608.202(a)(1)(C).

The IOWSG has stated (Tr.1 at 216, Tr.2 at 43,

Ex.

4,

P.C.

12) that investor-owned public water supplies do not

have the authority to adopt and enforce a plumbing code.

Therefore when adopting “conditions of service,” the group

members will be forced to opt for the third choice which requires

tke

1nstailation.~

of cross-connection devices at all_service

connections, except single family residential dwellings.

Thus,

IOWSG notes that the exemption provided to certain institutional,

commercial or industrial establishments will not apply to

investor owned water supplies.

The IOWSG opined

(P.C.

39) that

the Agency proposal

(Section 608.202(a)) was therefore

discriminatory against the investor owned water supplies and

their customers.

The Board believes that the IOWSG has a valid concern.

The

Board notes that the intent in exempting connections covered by

proposed Section 608.302(b)

is based on the hazard associated

with

such

connections

and

not on the ownership of the public

water supply.

The Board finds that it is reasonable to include

such an exemption in Section 608.202(a) (1) (C) to respond to the

concerns of the IOWSG.

The Agency proposal did not specifically exempt or include

multi-family residential dwellings.

Thus, the IOWSG observed

(P.C.

39) that the Agency proposal (Section 608.203(b)) would

exempt certain institutional, commercial,

or industrial

establishments, while multi-family residential dwellings having

comparable water use would not be exempt.

The Board agrees that

the exemption should be extended to multi-family dwellings with

comparable water supplies.

Therefore,

the instant proposal is

written to exempt multi-family residential dwellings (Section

608.307).

Cross-Connection Control Survey.

Section 608.202(b)

and

(C)

requires the official custodian of the public water supply to

perform a cross—connection control survey of the public water

supply distribution system once every two years and maintain an

inventory of water uses by service connection.

The IOWSG

expressed concerns about these requirements

(P.C.

39) which are

discussed separately below.

Freauencv of the cross—connection control survey.

The IOWSG

stated that the proposed 2-year frequency for conducting the

cross—connection control survey would not be cost effective, and

would place an undue burden on the ratepayer.

The group

suggested that the frequency be decreased to once every

5 years.

The Board notes that the investor owned water supply group did

not provide any cost information supporting the suggestion to

decrease the survey frequency.

The EcIS also does not provide a

specific cost estimate of conducting the survey.

Therefore, the

Board will retain the requirement that a survey shall be

conducted every two years.

0136-0278

---

Who is restonsible for conducting the survey?

The IOWSG noted

that the language requiring the “official custodian” of the

public water supply to conduct the cross-connection control

survey is vague and does not accurately state who is responsible

for conducting the survey.

The term “official custodian” has

been defined under the Board’s public water supply regulations at

35 Ill. Adm. Code 601.105. The official

~t~1añi~ffjcèr

of an organization that owns or operates a public water supply,

and who has direct administrative responsibility for the supply.

The definition of “official custodian” shall be included in the

definition section at Section 608.102.

Inclusion of industrial,

commercial, and institutional

establishments in the survey.

The IOWSG recommended that Section

608.202(b)

should require the cross-connection control survey to

include all industrial,

commercial,

and institutional

establishments which provide their own water supply, but which

can have cross—connections to the public water supply.

According

to the instant proposal, the cross—connection control survey must

account for all cross—connections to the public water supply

distribution system.

Thus,

the proposal clearly includes all

establishments which have cross-connections,

whether or not they

have their own water supply.

No revisions are necessary.

Standards or criteria for conducting the cross—connection control

survey.

The IOWSG stated that the proposed cross-connection

control survey requirements at Section 608.202(b) and

(c) do not

provide any survey standards or criteria.

The IOWSG recommended

that such standards or criteria be established in the

regulations.

Since the Agency proposal does not prescribe

standards or criteria for conducting the survey, the IOWSG

concerns appear valid.

The only specification in the Agency

proposal is that the survey shall inventory water uses by service

connection.

The Agency proposed requiring the cross—connection survey of

the public water supply distribution system to develop a list of

all connection devices possessed by the water consumer, and dates

of most recent inspection and testing

(Tr. 1 at 57).

The Agency

envisions that the water purveyor will use this information to

develop an inventory of service connections, water use, and

backflow protection needs within the individual premises

(Tr.1 at

57).

To develop and maintain a cross—connection control survey

database, it would be useful to have a set of criteria which can

be used by the water purveyors.

Involvement of local aovernment agencies in conductina the cross-

connection control survey.

The IOWSG believes that the cross—

connection control survey should be conducted by the local health

departments instead of the public water supply

(P.C.

39).

The

Agency stated

(P.C.

19) that it would be inconsistent with Ill.

owned water supplies to foist the responsibility upon State or

local government for the implementation of a cross—connection

control program for the company’s customers.

Since maintenance

of the water quality in the public water supply distribution

system is the responsibility of the water purveyor under the Safe

Drinking

~Water

Act1

the~Board_believes-that-~any-~program.

requirements such as the cross—connection control survey that are

implemented to fulfill the purveyor’s responsibility are best

carried out by the water purveyor.

Control of

Cross-Connections

and Inter-Connections to Public

Water

BuDD1Y.

According to the instant proposal at Section

608.202(d), the owner or official custodian of a public water

supply is responsible for the control of all cross—connections

and interconnections to the public water supply.

This is the

same as the current Board regulation at 35 Ill. Adm. Code

607.104(c)

The IOWSG expressed strong objections to this requirement.

The group stated that it will increase liability claims against

the owner or operator of the public water supply and that this

action places a broad legal duty on the public water supply (Tr.2

at 85-86).

The IOWSG stated that only the installation of cross-

connection control devices at all service connections will

protect the public water supply from liability exposure since the

users and not the public water supply have the actual control of

cross—connections and interconnections

(P.C. 41).

The Board was

requested to delete this requirement or evaluate the economic

impact of the regulations under the assumption that the

installation, inspection, and testing of cross—connection control

devices will be required at all service connections

(P.C.

12 and

41)

The liability issues associated with the proposed

regulations were addressed by the Agency in testimony presented

at the merit hearings (Tr.1 at 52—56, Tr.2 at 83—89).

The Agency

stated that the proposed requirement is an existing requirement

under 35 Ill. Adm. Code 607

•

104 and therefore, does not, place any

new responsibilities on the public water supply.

In addition,

the Agency noted that under the Safe Drinking Water Act

(42 U.S.C

300h et seq.), the public water supply has the responsibility to

deliver potable water meeting the Safe Drinking Water Act

standards at the consumer’s tap.

However, a public water supply

is not responsible for any contaminant that may be introduced

into the private water system by the user of the private water

system.

The public water supply is responsible if a contaminant

from a private water system flows back in the public water supply

distribution system through a cross—connection.

Therefore, whether or not proposed Section 608.202(d)

is

adopted by the Board, the public water supply would be liable if

the requirements of the Safe Drinking Water Act are violated.

0136-0260

---

7

However,

a public water supply subject to a liability action can

also initiate action against any person who might be responsible

for causing the contamination of the system.

The instant proposal at Section 608.202(d) does not subject

the public.. water_supply. to

..

any_additionalliabilityexposura.

since the regulation is currently in effect at 35 Ill. Adm. Code

607.104 (c).

An argument can also be made that the instant

proposal reiterates the responsibilities of the public water

supply under the Safe Drinking Water Act.

Therefore, the Board

proposes to retain the requirement at Section 608.202 (d)

IaDI.ications of Stat. Mandates Act

One issue raised by the IOWSG

(P.C.

38,43,52 and 53)

in this

proceeding has been whether or not the adoption of the proposal

would impose a state mandate on local governments.

The State

Mandates Act

(Ill. Rev.

Stat.

1991,

ch. 85, Sec. 2201 et. seq.)

defines a state mandate as any state initiated statutory or

executive action that requires a local government to establish,

expand or modify its activities in such a way as to necessitate

additional expenditures from local revenues.

The costs directly

attributable to the mandate are reimbursable, except under

specified circumstances.

Although the Board takes note of the State Mandates Act

and will discuss the implications of the State Mandates Act, the

Board must follow the mandates of the Environmental Protection

Act.

The Board is authorized by the Environmental Protection Act

to adopt regulations which protect health or the environment from

water pollution episodes as well as regulations requiring

inspection of equipment which may contribute to water pollution

(Section 13 of the Act).

In addition, the Board is authorized to

adopt regulations that ensure the maintenance of sanitary

quality, mineral quality, or adequacy of the public water supply

(Section 17 of the Act).

However, the Board is not required by

statute to enforce the provisions of the State Mandates Act, nor

is the Board authorized to appropriate funds for entities who may

be required to comply with Board regulations.

The requirements in the proposal that allegedly create the

new service mandates have been identified in the EcIS.

These

requirements include cross-connection control prescribed at

Sections 608.202 and 608.302, and recordkeeping specified at

Sections 608.501 and 608.502.

The Agency believes that the

proposed regulations do not create any service mandates as they

are merely a re—enactment of presently existing rules adopted

prior to the effective date of the State Mandates Act (P.C. 48).

The Agency specifically refers to its own Technical Policy

Statements adopted in Dec.

.

17,

1978 under the existing Board

regulations for cross—connection control

(35 Ill. Adm. Code

607.104).

0136-0281

The IOWSG believes

(P.C.

38 and 43) that the State Mandates

Act will result

in

arbitrary

and

discriminatory treatment of the

investor owned water supplies and their customers.

According to

the IOWSG, public water supplies owned by local governments will

not be required to comply with the cross—connection control

program unless the legislature appropriates monies to cover

~mplianc& có~

r~éqüired~

However, the IOWSG would be required to comply with the new

regulations. The IOWSG therefore maintains that adoption of the

instant proposal would negate the purpose of this proceeding,

which is to develop uniform regulations for cross—connection

control.

The IOWSG has questioned

(P.C.

52 and 53) the Agency’s

argument that the proposed regulations are the re—enactment of

the existing regulations and stated that the policy statement

adopted by the Agency is not legally binding since it has not

been formally adopted by the Board.

In addition, the IOWSG has

noted that the provisions regarding cross—connection control

adopted by the Agency prior to enactment of the State Mandates

Act were only recommendations to public water supplies and none

of the provisions were framed in mandatory language until

1984.

The DENR’s witness, Mr. Lee Zelle, stated that the

regulations create new service mandates since public water

supplies are not required to implement a comprehensive cross—

connection control program under the existing Board regulations

at 35 Ill. Adm. Code 607.104.

According to Mr.

Zelle, the intent

of the existing Board regulations is to control cross—connections

between two or more water supply systems (defined as

“interconnections” under the proposed regulations) and not all

connections to the public water supply distribution system

(Tr.3

at 32—33).

The Board does not agree with Mr. Zelle’s contention that

the intent of the existing Board regulation

(Section 607.104)

is

to control only cross—connections between two or more water

supply systems.

Clearly, Mr. Zelle was referring to Section

607.104(a) which states:

“No physical connection shall be permitted between the

potable

portion

of

a

supply

and

any other water supply

not of equal or better bacteriological and chemical

quality as determined by inspection and analysis by the

Agency,

except as provided for in subsection

(d).”

However, Mr.

Zelle overlooked Section 607.104(b) which clearly

prohibits cross—connections:

“There shall be no arrangement or connection by which

an unsafe substance may enter a supply.”

0136-0282

The

Agency

maintains

that

its

Technical

Policy

statements

required implementation of most provisions of the proposal prior

to the enactment of the State Mandates Act.

The IOWSG, however,

maintains that the proposal consists of numerous “new” service

mandates which local governments will not need to comply with

.absent reimbursement.~from...the~tate~

In summary, the Board is authorized by the Environmental

Protection Act to adopt regulations to protect health and the

environment from water pollution episodes.

Presently, Section

607.104(b)

prohibits cross-connections.

The instant proposal

attempts to clarify the current regulations.

The record in this

proceeding does not clearly indicate whether the adoption of this

proposal would create any new service mandates.

However, the

Board must rely on its specific authority to promulgate

regulations.

Therefore,

although the Board analyzed the state

mandate issue raised by the IOWSG; the Board cannot fail to

proceed with a regulation because it may impose such a mandate.

CROSS-CONNECTION CONTROL DEVICES AND INSTALLATION REQUIREMENTS

The

instant

proposal generally’ follows the Agency proposal

(Sections 608.203 to 608.207) with regard to regulations for

cross—connection control devices and installation.

Cross—

connection control requirements applicable to institutional,

commercial, and industrial establishments, and fire safety system

connections are found in Sections 608.301 to 608.305 of the

instant proposal.

The proposed regulations require installation

of cross—connection control devices or an annual inspection,

based on the hazard level

(high or low)

of the service

connection.

The

Board received a few comments from the IOWSG regarding

the application of cross-connection control devices and hazard

classification.

On reviewing the Agency proposal, the Board

found that applicability of the proposed requirements

(i.e. who

does what) needed clarification.

In addition, retrofitting

requirements for existing service connections not connected to a

fire safety system were not specified in the Agency proposal.

A

discussion of these issues and the IOWSG’s concerns is presented

in the following section.

Gneral

Concerns

ApDlicabilitv. The proposed cross—connection control requirements

at Sections 608.302-305 require a number of actions that must be

implemented at institutional, commercial,. industrial,

and fire

safety system connections to public water supply public water

supply

distribution

systems.

Under the Agency proposal (Sections

0 136-0283

---

10

608.203-206) the owner or operator of an affected establishment

appeared to be the intended party responsible for carrying out

the cross—connection control requirements.

However, the Agency

proposal did not clearly identify the persons or entities

responsible for carrying out the cross—connection control

reqiirements

except~for~S.ection

~60~8

.,20~3.(alwhichkdentifie

e

owner or operator of an affected establishment as the responsible

party.

To avoid confusion regarding the implementation of the

various cross—connection control requirements, the Board believes

that the proposal must clearly identify the persons or entities

responsible for complying with such requirements.

In drafting the instant proposal, the Board includes all

Sections dealing with the cross—connection control. requirements

(Agency Proposal Sections 608.203—207) under a separate Subpart

(“Subpart C”).

An applicability Section was added within the new

Subpart which clearly specifies the persons or entities covered

by the proposed requirements.

The Board proposal clarifies the

Agency’s intent by requiring the owner or operator of any

affected establishment to meet the cross—connection control

requirements.

Retrofit Reauirements.

In the instant proposal, retrofitting is

not mandated for low hazard connections’.

Section 608.302(a) (2)

of the instant proposal provides the owner or operator of an

establishment with a low hazard connection the choice of either

installing a cross-connection control device or opting for an

annual inspection.

This follows the Agency proposal (Section

608.203(a) (2)).

Since high hazard connections6 pose a greater potential

threat to human health, the instant proposal (Section

608.302(a) (1)) requires installation of a cross—connection

5”Low

hazard connection” means any vessel, piping arrangement,

or other direct connection to a public water supply containing any

solid, liquid, or gaseous matter, any odor.or form of energy which,

when present in the public water supply distribution system, may

cause

the water

to be aesthetically degraded to the

senses

of

taste, sight or smell without tending to cause any actual physical

illness or injury to persons consuming the water.

6”High

water quality standards of this Subtitle are not met or physical

illness or injure to persons consuming the water could result.

control device at such connections.

The proposal requires

installation of a reduced pressure zone

(RPZ) principle assembly

at high hazard connections.

More detailed discussion about space

limitations and retrofitting costs for such connections is given

in the following fire safety system discussions.

The general

çpnç~n,

a

iere

relates to compliance scheduling specified

by the regulations.

The regulations must provide a reasonable time period to

plan and implement

a compliance schedule which does not result in

undue economic hardship.

The Agency proposal (Section 608.206)

specified a 60-day compliance period for retrofitting existing

fire safety systems containing chemical additives with a RPZ

principle backflow assembly.

The National Association of Water

Companies has expressed concern regarding the proposed time—frame

for retrofitting an existing fire safety system

(P.C.

16

& 39).

The

National

Association

of

Water Companies has noted that due to

the non-availability of qualified personnel required to perform

the retrofit work and bidding and contractor scheduling delays,

it would be difficult to comply with the proposed requirements

within a 60-day period.

The National Association of Water

Companies suggested that the compliance time period be changed to

2 years.

The Board is persuaded by the National Association of

Water Companies and will propose a

2 year compliance schedule

(Section 608

•

302(d)).

The

IOWBG

Concerns

Application

of

Fixed

Proper

Air

GaD.

The IOWSG opined that a

fixed proper air gap7 is not an appropriate cross—connection

control device and therefore,

all institutional, commercial,

and

industrial establishments must be required to install a RPZ

principle backflow assembly.

(Tr.1 at 219, and P.C.

16

& 39.)

The IOWSG believes that a customer could easily make changes and

create a cross-connection at a connection protected by a fixed

proper air gap, but that the customer is unlikely to do so once a

RPZ principle back flow assembly is installed.

The installation of a fixed proper air gap at service

connections is a recognized method of preventing cross—

connections recommended by the AWWA Manual M14

(Ex.

7) and

prescribed as a cross—connection control measure under the

Illinois Plumbing Code.

The IOWSG’s concern regarding customers’

actions may affect connections protected by any device, and not

Therefore,

the Board proposes the use of a

connection protection to the public water supply.

P.C.

16 & 38) that the proposed classification of service

connections as low or high hazard connections is ambiguous, and

recommended that the proposal identify the type of customers that

fit

each, category.

The

IOWSG

suggested

(Tr.2

at

71)

that

the

Board consider, as a starting point, the customer hazard

classification list adopted by the Foundation for Cross-

Connection Control and Hydraulic Research at the University of

Southern California

(Ex. 14).

However, upon questioning by the

Agency, the IOWSG witness admitted (Tr.2 at 120) that it would be

impossible

to

classify

a

connection as either a low or a high

hazard connection without evaluating the hazard associated with

the connection.

In view of this,

the Agency proposal (Section

608.203) to specify cross-connection control requirements based

on classification of hazards as high or low is appropriate.

Accordingly, this is incorporated in the instant proposed

regulations at Section 608.302.

The

Board

proposes

(Section

608

•

302(a) (3)) that the public

water supply determine the hazard class of a service connection.

The Agency proposal

(Section 608.203) required the owner of an

affected establishment to determine the hazard level of the

service connection

to

the

public

water

supply.

The

Board

notes

that in the instant proposal

(608.202(d)) and in the current

regulations

(607.104(c)), control of all cross—connections is the

responsibility of the owner or custodian of the public water

supply.

Therefore, the Board believes that the determination of

hazard class

(high or low) should be made by the party with

ultimate responsibility for control of cross—connections.

The

Board

also

notes

that

compliance

with

Section

608.202

of

the

proposed

regulation

will

give

public water supplies all the

information needed to determine the hazard class of service

connections.

The public water supply is required to conduct a

cross—connection survey of the public water supply distribution

system every two years

(608.202 (b)).

The survey shall include an

inventory

of

water

uses

at

each

service

connection

(608.202(c)).

The survey results and inventory of uses will allow the public

water supply to classify connections as high or low hazard using

the

definitions

in

the instant proposal.

FIRE

REQUIREMENTS

Background

Present

Board

regulations

(35

Adm. Code 607.104) do not

0136-0286

---

specify

cross—connection

control

requirements

applicable to fire

safety

system

connections.

The Agency’s original proposal

(Oct.

20,

1988)

required the installation of a reduced pressure zone

(RPZ) principle backflow assembly at the fire safety system

connections whenever: chemical additives are used in the fire

safety~.system~water

is pumped ~rflows~.~by.gray tyinto~the~f

ire

safety system from another source; or there is a connection

through which water can be pumped into the fire safety system

from another source

(Section 608.204, Original Proposal).

Solid

opposition to this original Agency proposal was expressed by

representatives of the fire protection community (the Illinois

Fire Chiefs Association

(Fire Chiefs), the Illinois Fire

Inspectors Association

(Fire Inspectors), the Society of Fire

Protection Engineers

(Fire Engineers), the Chicago Association of

Commerce

and

Industry8

(CACI),

the Illinois Fire Advisory

Commission

(Fire Commission), the National Fire Sprinkler

Association

(Fire

Sprinkler

Association)

and

a

number

of

consulting

fire

protection

engineers).

The

fire

protection

community

presented

extensive

testimony9 at the first set of public hearings (May 25

& 26,

1988).

The

common

theme of their testimony was that installing a

RPZ device at an existing fire safety system connection would

result

in

a

significant

pressure

loss

in

the

fire

safety

system

and

compromise

fire

suppressing

ability.

Testifiers maintained

that redesigning existing fire safety systems to allow for the

increased

pressure

loss

would

be

very

expensive

‘(Tr.l

at

171,

182,

202,

233,

487,

488).

To

address

these

concerns,

the

fire

protection community recommended that the Board consider adopting

the

American

Water

Works

Association

(AWWA)

Manual

1414

recommendations

(Exhibit

7)

or

the

amendments

proposed

by

the

CACI

which

are

based

on

the

AWWA

recommendations

(Tr..

at

173,

234,

509,

523).

After

the

first

set

of

hearings,

the

Agency

responded

to

the

fire

protection

community

concerns

and

issued

a

revised

proposal

(Oct.

11,

1988)

including

cross—connection

control

requirements

and retrofitting requirements specifically intended for fire

safety system connections.

The Agency made further changes after

negotiations with the fire protection community and filed an

“amended” proposal on May 1, 1989 which is now being considered

by the Board.

Among

the

three

major

groups

representing

the

fire

protection

community,

the

Fire

Chiefs

(P.C.

68)

and

the

Fire

Inspectors

(P.C.

35) supported the Agency’s amended proposal, and

the Fire Sprinkler Association

(P.C.

58) opposed the amended

proposal and suggested that the Board adopt the AWWA Manual M14

recommendations.

In addition,alar~genumbsr of individual fire

protection districts expressed concerns with the Agency’s

proposed fire safety system requirements and instead recommended

the CAd’s alternate proposal based on the

AWWA

manual 1414

(P.C.

59—67

& 69—72).

The more recent comments

(P.C.

83, 86,

87,

88) filed after

March 26,

1992 show that the various groups have not changed

their positions, with one exception.

The Fire Inspectors

(P.C.

88) no longer support the Agency proposal in light of the EcIS

findings, and requested that the Board draft new regulations

using the EcIS as the basis.

Discussion

Testimony and comments in this proceeding indicate that the

fire protection community is not opposed to cross—connection

control at fire safety system connections.

However, the major

fire protection groups do not appear to agree on what type of

cross—connection control requirements are appropriate for fire

safety system connections.

As noted earlier, the Fire Chiefs

supported the Agency proposal whereas the other groups recommend

adoption of the AWWA’s Manual 1414 recommendations included in the

CACI’s alternate proposal.

Another development that needs to be

considered is the inclusion of cross—connection control

requirements applicable to fire safety system connections in the

Illinois Plumbing Code (amendments of Jan 10,

1990)

adopted by

the Illinois Department of Public Health.

The differences between the cross—connection control

requirements recommended by the AWWA, the Illinois Plumbing Code,

the Agency, and the CACI are given in Appendix B.

The comparison

indicates that the AWWA’s recommendations have generally been

incorporated in the Agency proposal, the CACI proposal,, and the

Illinois Plumbing Code.

A major difference is the recommended

cross—connection control for fire safety systems served solely by

the public water supply

(i.e., without any auxiliary connections

to nonpotable water or chemical additives).

For such

connections, AWWA Manual

1414 and CACI recommend no cross—

connection control device (single weighted check valve), whereas

the Agency proposal and the Illinois Plumbing Code require a

double detector check valve assembly (DDCVA).

Also, the fire

safety system requirements prescribed by the Illinois Plumbing

Code

(35 Ill. Adm. Code 890.1540) are the same as the Agency

proposal (608.204).

New Fire Safety Svste* Connections.

The major impact of

requiring

cross-connection

control

at

all

new fire

safety

system

connections

would

be

the

additional

installation

cost

of

the

cross—connection control device at such connections10.

However,

since the proposed fire safety system requirements are the same

as~

.thQse spe~ifie&inthei21inois~Plumbing~Code~(35 Ill._Adm.

Code 890.1540), cross-connection control requirements for new

fire safety system connections in the instant proposal will not

pose an additional financial burden on the regulated community.

Whether or not the instant proposal is adopted by the Board, all

new fire safety system connections are required to comply with

the Illinois Plumbing Code.

Therefore, the Board finds that the

fire protection community objections to this proposed requirement

are no longer valid.

The

instant

proposed

regulations

will

retain

the

fire

safety

system requirements in Section 608.204 of the Agency proposal

with two minor changes.

The reference to the exception

conditions prescribed in Section 608.205(a)

of the Agency

proposal will cite section(b)

instead of

(b) (2).

The term

“preventer” will be changed to “assembly” to be consistent with

the terminology proposed in the definition (Section 608.102).

Existing

Fire

Safety

System Connections.

The Agency proposal

contained retrofit requirements that are specifically intended

for the existing fire safety system connections.

The fire

protection community has expressed concern regarding the proposed

retrofit requirements and recommended that the Board instead

adopt the AWWA Manual Ml4 recommendations.

The Board reviewed

both the Agency proposal and the recommendations of the fire

protection community before fashioning a proposed regulation to

cover existing fire safety systems with and without chemical

additives.

According to the Agency proposal (Section 608.206), all

existing fire safety systems which do not contain any chemical

additives are required to be retrofitted with a double detector

check valve assembly

(DDCVA) whenever physical space for

installation is available.

If space is not available for

installation of a DDCVA, existing fire safety system connections

shall be retrofitted with a weighted detector check

(WDC)

and an

alarm valve.

Based on the information presented in the EcIS

(pp:

88),

DDCVA may be

installed

at

less

than

one

percent

of

the

existing fire safety system connections due to lack of space.

~°In

addition

to

the

installation

cost,

both new and existing

FSS connections are subject annual inspection and testing under the

Agency’s proposal.

According to EcIS estimates, the inspection and

testing

cost

for

FSSs

would

be $9.6 million per year plus

$

0.26

million

to

account

for

new

FSSs

installed

each

year..

0136-0289

---

16

Therefore, under the Agency proposal most of the existing fire

safety

system

connections

without

any

chemical

additives

will

have to be retrofitted with a WDC and an alarm valve. Under the

AWWA Manual

1414 recommendations, such connections would only

require retrofitting with a WDC.

According to the EcIS

(pp:

89-90), the cost of retrofitting

existin9 fire safety systems with a WDC would be

$

11.7

millionul.

Retrofitting existing fire safety systems with a WDC

and an alarm valve connected to an approved fire receipt point

would cost

$

198 million12.

A major portion

($

186 million) of

the total cost of retrofitting is associated with installation of

alarm valves and providing connections to approved fire alarm

receipt points.

The alarm valve is a mechanical device designed to transmit

a signal to a remote fire alarm receipt point. The alarm is

activated when flow occurs through the valve in either direction

and alarm valves are usually installed in each riser of the fire

safety system.

The alarm valve is generally used as an early

warning system to alert fire fighting personnel of a potential

fire, system leakage, or unauthorized use of water.

The Agency

has not explained how the alarm valve will prevent backflow

through the WDC.

It appears that when a WDC fails to shut-off in

a backflow situation, the alarm valve will transmit a signal to

the remote fire alarm receipt point.

However, the Agency

proposal did not specify appropriate action when the fire alarm

is triggered as a result of backflow in the system.

Therefore,

the usefulness of the alarm valve for backflow prevention is

questionable considering the high cost associated with its

installation.

The EcIS

(pp: 88) stated that the alarm valve is a

fringe

benefit

used

only

in

top

flight

systems.

Section 608.206(b) of the Agency proposal requires

retrofitting existing fire safety systems with a RPZ principle

device only if such systems contain chemical additives such as

antifreeze and fire retardants.

The Agency assigned the highest

priority to this type of fire safety system for retrofitting

backflow prevention devices (PC. 74).

The fire protection

community appears to be in agreement with the proposed

requirement since the AWWA Manual 1414 recommends maximum

protection for any fire safety system containing anti—freeze or

~The estimate is based on retrofitting 10 percent

at

an

cost of

2,437.50 per retrofit.

The remaining 90 percent of the

existing FSS connections are already protected by a WDC.

other

chemical

additives.

The

potential

for

contaminating

the

water

supply

with

dangerous

chemicals

justifies

the

retrofitting

requirement

for

existing

fire

safety

systems

with

chemical

additives.

Therefore, ~

retains the cross—connection control requirement offered at

Section 608.206(b)

of the Agency proposal for existing fire

safety systems containing chemical additives.

However, the

Agency proposed (Section 608.206(a)) retrofitting existing fire

safety systems with a DDCVA if chemical additives were not

present in the system.

The instant proposal at Section

608.305(a) will not retain the Agency language, since less than

one percent of such systems have adequate space for the

installation

of

a

DDCVA.

The

instant

proposal

(Section

608.305(a))

requires

all

existing fire safety systems which do not contain any chemical

additives

to

be

retrofitted

with

a

WDC and does not require the

installation of an alarm valve along with the WDC as proposed by

the Agency (Section 608.206(a)).

Since more than 90 percent of

the estimated retrofitting cost is associated with the

installation of the alarm valves and providing connections to

remote

fire

alarm

receipt

points,

the

financial

burden

imposed

by

this option on the regulated community will be minimal compared

to the Agency proposal.

However, since some jurisdictions may

opt for alarm valve installation, the instant proposal includes

alarm valve requirements from the Agency proposal.

Also, the

proposed option is consistent with AWWA Manual 1414

recommendations

which

is supported by the fire protection

community.

DEFINITIONS, TERMINOLOGY AND ORGANIZATION

In the Agency proposal, there were many variations in the

terms

used

to

denote

the

system

which

distributes

potable

water

to the public.

In particular, the terms public water ‘supply,

public water supply system, public water supply distribution

system, community water supply system, and potable water supply

were

used loosely and at times,

interchangeably.

The instant

proposal attempts to standardize terms both within the proposal,

and in relation to the Act and current Board regulations.

Participants should pay careful attention to the definition

and usage of the terms “public water supply”,

“private water

system”, and

“public water supply distribution system”.

The

definition

for

“public

water

supply”

is

taken

from

the

Act

(citation),

and

includes

the endpoint at the service connection

which conforms to Board regulation at 35 Ill. Ada. Code 601.102.

The defintion of “private water system” in the instant proposal

includes

all

structures

carrying

potable

water

which are not a

0136-0291

---

18

part

of

the

public

water

supply.

“Public

water

supply

distribution system” as defined in the instant proposal includes

all points downstream of an entry point through which potable

water is distributed.

Therefore,

“public water supply

distribution system” goes beyond the public water supply which

ends at the~s.erv.ice.connection. T~e~p~1~ate

si~pp)~

distribution system” includes the public water supply, as well as

all points beyond the service connection which distribute potable

water.

The Board notes that the definitions for these three

terms in particular are different from the way the terms are

defined under the SDWA regulations.

However, these definitions

appear to accurately reflect the intent of these regulations.

Also, the Agency proposal prescribed several types

of

backflow prevention devices for specific types of cross—

connections.

In

most

cases,

the

definitions

of

the

terms

describing such devices were provided in Section 608.102 of the

Agency ‘proposal.

However,

a few terms were not used

consistently.

At several locations in the Agency proposal,

a

single type of backflow prevention device was referred to by

different terms.

Also, some terms were not defined.

A few

examples from the Agency proposal are provided for illustrative

purposes:

1)

The

term

“Air

gap”

is

defined

in

Section

608.102.

However,

the same term is referred to as the “fixed proper air gap”

at

Section

608.203(a)

2)

The terms “RPZ principle backflow assembly” and “RPZ

principle

backf low

device”

are

defined in Section

608.102.

The

proposed

regulations

refers

to

the

same

device

as

the

“RPZ backflow preventer” at Section

608. 206.

3)

The terms “single check valve”, “weighted detector

check”,

“alarm valve”, and “weighted clapper” used in

Section 608.206 have not been defined.

Terms have been defined at Section 608.102 of the instant

proposal.

To avoid confusion and to ensure proper specification

of backflow prevention devices, the instant proposal will use the

various terms consistently.

Participants should carefully

consider the definitions and provide appropriate comments to the

Board.

Many sections of the Agency proposal were used in the

instant proposal with minor editing changes.

These changes were

necessary to clarify the rules,

or to make them more acceptable

to the Legislative Joint Committee on Administrative Rules.

A

Comparison of the Cross-Connection Control

Requirements

for Fire Safety Systems ReCorninendefi

by the American

Water

Works Association

(AWWA), Specified

in the Illinois

Plumbing Code

(IPC)

and those Proposed in R87-37

I.

Class

I--direct connections from public

water mains

only;

no pumps, tanks, or

reservoirs;

no phy8ical connection from

other water

supplies; no

antifreeze or

other additives of any

kind; all

sprinkler drains discharging to

atmosphere, dry wells, or other safe

outlets.

2.

Class

2—same

as

Class

I, except that

booster pumps may be

installed in the

connections from the street

mains

(Booster pumps do

not affect the

potability of the system;

it is necessary,

however, to avoid drafting so much

water that pressure in

the water main

is

reduced below 10 psi.)

Generally, fire

protection systems of

Classes

I

and 2 will

not require

backflow protection at the

service

connection.

Pumper connections of

automotive fire

department equipment

to

street hydrants are not ordinarily

health hazards,

3.

Class 3—direct connection from public

water supply main

plus one or more of

the following: elevated

storage tanks;

fire pumps taking

auction from above-

ground covered reservoirs

or

a)

Fire safety

systems connected to a

public

water supply shall be equipped with a

double detector check valve assembly

located

at

the point of connection between

the fire

safety system and the public water

supply service

line to protect the

community public water supply against

backflow and backsiphonage except under

the conditions described in

subsection

(b)(2).

b)

A fixed proper sir gap with a

break tank

or other storage vessel

or a

reduced

pressure principle backflow preventer shall

be installed at the point of connection

betweenthe

fire safety system and the

public water supply service line

to protect

the community water public

supply against

backflow and backsiphonage when:

I)

The fire

safety

system contains

additives such as

antifreeze, fire

retardant or other chemicals.

The

RPZ assembly may be

located

at

the

point of connection to the section of

the

system containing such additives

when the connection to the public

water supply is protected by a

double detector check valve

assembly; or

b)

5)

A

reduced pressure zone assembly

shall be

installed to protect the

community water supply against

backflow and backsiphonage in

fire

lines

or fire

safety

systems

connected to the public water

distribution system when:

A)

the

fire

safety

system contains

antifreeze, fire

retardant, or

other chemicals.

The RPZ

assembly may be

located at

the

point of connection to the

portion of the system

containing such

additives; or

B)

water is pumped into the fire

line or fire

safety system from

an auxiliary non-potable

source dedicated for

fire

service use; or

C)

water flows into the

fire

Line

or fire

safety system by

gravity from a an auxiliary

non-potable source

dedicsted@d for fire service

d)

Fire

safety systems shall be equipped

with adouble detector check valve

assembly located at the point of

conne4tion between the fire

safety

system

and the water supply line

to protect

the

water ~upplyagainst backflow and

backsi~,honage

except under the condition

described in subsection (A) (2).

A fixed proper air gap with a break

tank or other storage vessel or a

~‘educed

pressure principle

t,ackflow preventer

shall be

installed at the point of connection

between tile

fire

safety

system and

~hewater supply service

line to

protect the water supply against

~i*ckflowand backsiphonage

‘~hen):

A)

The fire

safety system contains

additives such as antifreeze,

fire

retardant or other

chemicals.

The

RPZ

assembly

may be located at the point of

connection to the section of the

system containing such

additives when the connection

to the water supply is protected

by

a double detector check

valve assembly;
