1100 West 49th Street         of on-site sewage     disposal
Austin, Texas   78756-3199    systems, and related questions
                              under chapter    366  of   the
                              Health and Safety Code
                              (RQ-2037)
Dear Dr. Bernstein:
      you ask three questions concerning state and local
 regulation of installers of on-site sewage disposal systems1
 under chapter 366 of the Health and Safety Code.     Chapter
 366 codifies article 4477-7e, V.T.C.S., which was repealed
 effective September 1, 1989, the date the Health and Safety
.Code took effect. Acts 1989, 71st Leg., ch. 678, § 13, at
 3165.
     Since your second question is narrower than your first,
we will address it first. you ask whether an "authorized
agent" as defined in chapter 366 may require installers to
meet more stringent registration standards than        those
required by the Texas Department of Health [the "depart-
ment"] pursuant to section 366.073. The registration of


      1. On-site sewage disposal systems for purposes of
chapter 366 are treatment devices and disposal facilities
that produce not more than 5,000 gallons of waste each day,
are used only for disposal of sewage produced on site, and
are not regulated by the Texas Water Commission.           Id.
S 366.002(B).     For the most part, these systems are septic
tank systems, aerobic treatment plants and other treatment
devices used by homeowners and small businesses.           m

installers is covered by subchapter E of chapter 366.     It
provides that no person may operate as an installer in Texas
unless registered by the department or an authorized agent.
Health & Safety Code 8 366.071. Section 366.073(a) requires
the department to issue or authorize the issuance of
installer registrations. Section 366.073(b) provides that
the department shall issue a registration to an installer if
he completes both an application in compliance with chapter
366 and the training program provided by the department.
     "Authorized agents" are local governmental entities
designated by the department to implement and enforce
chapter 366 and the rules adopted by the Texas Board
of Health under chapter      366.   Health   & Safety   Code
5 366.002(l); gee also iB, 5 366.033.       For purposes of
chapter 366, the phrase "local governmental entities" refers
to municipalities, counties, river authorities or special
districts. &     0 366.002(6). According to section 366.011,
either the department or an authorized agent has "general
authority over the location, design, construction, installa-
tion, and proper functioning of on-site sewage disposal
systems." Neither subchapter E nor any other provision in
chapter 366 or its predecessor, article 4477-7e, states that
state registration in accordance with chapter 366         '
exclusive .or that authorized agents may not impose rnoi:
stringent installer registration standards or require state
registered installers to register locally. In fact, the one
reference in chapter 366 describing departmental registra-
tion of installers as "statewide" does not indicate any
legislative intent to prohibit more stringent local regula-
tion of installers. a       ia, 0 366.077(a) (permitting an
authorized agent as well as the department to revoke an
installer's "statewide registration" for violating chapter
366 or rules adopted under the chapter).
     Subchapter C of chapter 366 requires a local govern-
mental entity desiring designation as an authorized agent
to hold a public hearing and adopt an order or resolution
satisfying certain statutory    requirements so    that  it
rather than the department may exercise the general author-
ity provided by section 366.011. Health 6 Safety Code

department approves the order or resolution in writing.

     The order or resolution must satisfy the departmentIs
minimum requirements for on-site sewage disposal systems and
include a written enforcement plan. Ig, S 366.032(a); -

                                P. 6849
Dr. Robert Bernstein - Page 3 (JM-1278)




however, in   accordance   with   section   366.032(b)   which
provides:
        If the order or resolution adopts more strin-
        gent standards for on-site sewage disposal
        systems than this chapter or the department's
        standards and provides greater public health
        and safety protection, the authorized agent's
        order or resolution     prevails over    this
        chapter or the standards.
We conclude the legislature intended section 366.032(b) to
authorize any governmental entity that is an authorized
agent to adopt more stringent standards and for such
standards to prevail after their adoption. Our construction
is consistent with the language of article 4477-7e, from
which section 366.032(b) was derived, and with the testimony
presented to the legislature in 1987 on behalf of House Bill
1875, the bill that enacted article 4477-7e.
     Section 366.032(b) modifies and combines language from
sections 5(c) and 13 of article 4477-76, V.T.C.S.      Acts
1987, 70th Leg., ch. 406, at 1935, 1938.       Section 5(c)
stated "[t]he order or resolution may adopt more stringent
standards for on-site sewage disposal systems than the
department's standards." L    at 1935. Section 13 stated:
       A local governmental. entity's orders and
       rules that are more stringent than this
       article or rules adopted under this article
       and that provide greater protection to the
       public health or safety prevail in the local
       governmental entity's jurisdiction.
J,& at 1938. The language in section 5(c) that an "order or
resolution may adopt more stringent standards for on-site
sewage disposal systems" clearly constitutes authority for
any governmental entity who is an authorized agent to adopt
more stringent standards, and we conclude that the modifi-
cation of this language from section 5(c) and its combina-
tion with language from section 13 was not intended to make
a change in the law.2


     2. Repeal of these and other sections of article
4477-7e and enactment of chapter 366 was part of a non-
substantive codification of existing health and safety laws
and thus was not intended to make substantive legal changes.

     Furthermore, the testimony offered in 1987 on behalf of
House Bill 1875 supports our conclusion that the legislature
intended counties and other local entities to have the power
to adopt more stringent standards. Several speakers at a
public hearing held in 1987 on House Bill 1875 referred to
the bill as a means of implementing minimum standards
statewide. Those speakers stated that minimum state stan-
dards would discourage incompetent installers from moving
from counties that currently regulated sewage disposal
systems and installers to counties without such regula-
tions.3 They also testified that the adoption of minimum
state standards in conjunction with a grant of authority to
authorized agents to collect permit fees, 5ee Health &
Safety Code S 366.059, would encourage additional counties
to regulate sewage disposal systems locally and thereby
avoid departmental regulation within their jurisdictions.
No mention was made of any intent to restrict more stringent

     3. In 1987 sections 26.031 and 26.032 of the Water
Code authorized county commissioners courts to regulate
private sewage facilities     within their    jurisdictions.
Testimony at the public hearing indicated that between 70
and 110 counties were regulating sewage facilities and their
installers locally. winas     on Tex. H.B. 1875 Before the
Hou e Comm. on Natural Resources, 70th Leg. (March 25, 1987)
(teztimonies of Larry Soward and R.J. King) (tapes on file
with House Technical Services). House Bill 1875 repealed
sections 26.031 and 26.032 effective September 1, 1989, the
date that the bill required the rules to be adopted by the
state under article 4477-7e to take effect. Acts 1987, 70th
Leg., ch. 406, SS 2-3, at 1938. Given the current language
of section 366.032(b) of the Health and Safety Code, the
prior language of section 5(c), and the public testimony
stating minimum state standards were needed for counties not
regulating sewage disposal     facilities, the repeal     of
sections 26.031 and 26.032 does not indicate any intent to
deprive counties of their authority to regulate on-site
sewage disposal facilities     more stringently than     the
department.

were currently regulating     sewage facilities or   their
installers of their power to do so. See. e.a,, -inas    on

various state and local entities) (tapes available from

     The department's brief filed with us states that sec-
tion 366.032(b) of the Health and Safety Code does permit
authorized agents to adopt more stringent standards.    The
brief, however, concludes that authorized agents may adopt
more stringent standards only with regard to on-site sewage
disposal systems and not more stringent standards'for the
registration of installers who hold state registrations, We
disagree with this conclusion.
     Section 5(c) does expressly refer only to "more strin-
gent standards for on-site sewage disposal systems" and does
not contain express language referring to more stringent
standards for installer registrations.    Nevertheless, the
language of section 366.032(b) permitting authorized agents
in their orders or resolutions to adopt more stringent stan-
dards for on-site sewage disposal systems implies the powers
necessary to carry out the grant of the express power.

Statutes 0 118, at 701-02 (grant of express power conveys

chapter 366 or its predecessor, article 4477-7e, states that
state registration is exclusive or that localities may not
impose more stringent registration requirements.5 Thus, an

     5. One speaker testifying at the 1987 public hearing
on House Bill 1875 stated that the bill would not prevent a
local entity from imposing more stringent standards if it
wanted to license installers and require some additional
training. That speaker had participated in the Texas Rural
Water Quality Task Force whose work resulted in House Bill
                                        (Footnote Continued)

authorized agent who adopts more stringent standards for
on-site sewage disposal systems in its order or resolution
pursuant to section 366.032(b) may adopt more stringent
standards for local registration of installers if those
standards are necessary to ensure that local installers will
satisfy the    agent's   more stringent    disposal   system
standards.6
     We now turn to your first question. you ask if local
governmental entities,    whether or    not designated    as
authorized agents, may impose certain specific requirements
on installers who hold state registrations. you describe
the requirements as "paying fees, attending training cours-
es, posting surety bonds, or obtaining licenses or registra-
tions." The department's brief contends that chapter 366
preempts all local regulation not in conformance with its
provisions. You have not provided us with the texts of any
existing local orders, resolutions or ordinances adopting
such requirements. You also have not indicated either the
type of entity imposing the requirements or the legal
authority relied upon to impose specific local requirements.
Accordingly, we answer your question only generally.
      We address this question first with regard to local
governmental entities that have been designated as author-
ized agents and that possess the power to regulate on-site
sewage disposal systems only under chapter 366.   Consistent
with our first answer, authorized agents that have adopted
in their orders or resolutions more stringent standards for
on-site sewage disposal systems pursuant to section 366.032
may adopt additional regulatory requirements necessary to
achieve those more stringent standards as long as the addi-
tional requirements do not directly conflict with chapter
366! Consequently, to be valid, requirements for local
fees,,
     1 training, bonds, licenses, or registrations must
ensure compliance with the more stringent standards adopted

King, speaking on behalf of the Texas Department         of
Agriculture).

standards must not directly conflict with the department's
minimum standards. &8 infra Note 7 and accompanying text;

by authorized agents   for sewage   disposal   systems   within
their jurisdictions.
     We next turn to local governmental entities that
possess statutory or other legal authority outside of
chapter 366 to regulate on-site sewage disposal systems and
their potential threat to the environment and public health.
These entities may or may not be designated as authorized
agents. Local regulations are preempted by state law only
if the regulations are expressly prohibited by state law, if
the legislature intended state law to exclusively occupy the
field, or if the regulations directly conflict with state
law. &.8 Attorney General Opinions JW-790, 374-619 (1987).
     As we previously stated, we do not find in chapter 366
or in its predecessor, article 4477-7e, any express prohibi-
tion against local regulations that reflect local soil and
water conditions as well as local public health concerns.

statutory provision that local licenses not required) with
Attorney General Opinion JW-994 (1988) (no express prohibi-
tion in Controlled Substances Act on local regulation of
abusable glues).   Furthermore, the legislature expressly
repealed only sections 26.031 and 26.032 of the Water Code
when it passed House Bill 1875, and even then it replaced
those sections with section 5(c) of article 4477-7e, now
section 366.032(b) of the code. w    a,     n-3. No provi-
sion of either chapter 366 or article 4477-7e suggests the
legislature intended to repeal by implication any legal
authority to regulate on-site sewage disposal systems at the
local level.
     Implicit in our first answer was the determination that
the legislature did not intend chapter 366 or its prede-
cessor, article 4477-7e, to exclusively occupy the' field
of on-site sewage disposal regulation.    Read as a whole,
chapter 366 imposes minimum statewide standards and a state
registration requirement to protect communities       within
counties imposing little or no regulation. Chapter 366 does
not indicate any legislative intent to negate equivalent or
more stringent local regulation authorized by the charters
of home rule cities or by state laws.      Comnare Attorney

by state law indicates legislative intent to preempt local
bond requirements) &      Attorney General Opinion JW-790

legislative intent to occupy field and preempt all local
regulation) a     Attorney General Opinion JW-994 (1988)

Opinion JM-226 (1984) (state public health statutes do not
preempt municipal standards for storage of hazardous waste).
     In addition, various speakers at the public hearing in
1987 referred to a need for statewide minimum requirements
and the creation of incentives to encourage more counties to
regulate on-site systems. No speaker described House Bill
1875 Asia restriction on or implied repeal of local powers
to promote the public health and protect the environment.
See. e .a. &&rinas on TeX. H.B. 1875 m       (testimonies of
Mark Hoe&her.   Wavne Farrell, Larrv ioward and R.J. Kina).
Thus, we conclude -that the iegisliture did not intend -to
occupy the field     of on-site    sewage disposal    system
regulation.
     Nevertheless, local governmental entities may not adopt
regulations that impose standards in direct conflict with
chapter 366.7 Standards less stringent than those imposed
under chapter 366 would directly conflict with state law
and thus would be preempted.     &8 Health 61 Safety Code
55 366.032(a)(2), 366.034(b). Also preempted would be local
regulations allowing installers to construct or alter on-
site sewage disposal systems locally without state registra-
tions or approved permits as required by chapter 366.    See
&   59 366.051, 366.071.    Furthermore, additional pea
fees for costs covered by the state permit fees would
directly conflict with state law. Additional registration
and licensing fees also may not be charged by local entities
for costs already covered by the state registration fees.

registration, bonding or training requirement, however,
would depend on factual determinations that cannot be made
as part of the opinion process.
     Your last question concerns the registration of li-
censed plumbers as installers. you ask whether individuals
licensed as plumbers in accordance with article 6243-101,
V.T.C.S., must be registered as installers as required by
chapter 366.
     Chapter 366 does not exempt state licensed plumbers
from its registration requirements. Section 366.071 re-
quires all persons operating as installers of on-site sewage
disposal systems in this state to be registered by the
department or an authorized agent. As mentioned earlier, an
"installerw is defined by section 366.002(5) as any person
who receives compensation from another to construct, in-
stall, alter, or repair on-site sewage disposal systems.
See also 25 T.A.C. 55 301.107(a)(5), 301.107(j) (property
owner exempt from registration with regard to facilities on
his property).
     Neither does article 6243-101 exempt licensed plumbers
from the registration requirements of chapter 366.   Section
3(e) of that article currently provides that plumbers
holding a license from the Texas State Board of Plumbing
Examiners are not "required to be licensed by any other
board or agency when installing or working on a lawn irriga-
tion system.' No other provision of article 6243-101 or any
other state law exempts licensed plumbers from the registra-
tion requirements of chapter 366.
     We are aware that the statutory definitions of "plumb-
ing" and "on-site sewage disposal system" create some regu-
latory overlap. &S V.T.C.S. art. 6243-101, 5 2 (plumbing
includes all piping, appurtenances and appliances for the
elimination of sewage, including disposal systems): Health &
Safety Code 5 366.002(B) (one or more treatment or disposal
systems producing not more than 5,000 gallons of on-site
waste daily). Although particular actions may fall within
only one of the two definitions or within both definitions,
we are unable to resolve questions of fact in the opinion
process. Thus, we limit our discussion to the legal issue
of whether a state licensed plumber must obtain a state
installer registration to operate as an installer for
purposes of chapter 366.
     With regard to the legal issue,.this office has previ-
ously held that statutory exemptions are necessary to avoid
state licensing requirements.   See.%,     Attorney General
Opinion H-495 (1975); see also Attorney General Opinion



                                P. 6856

H-960 (1977) (affirming holding of H-495); Attorney General
Opinion H-890 (1976) (state agencies cannot create by
contract licensing exemptions not available by statute).
Therefore, we conclude that individuals holding valid state
plumbing licenses must also be registered as installers in
accordance with chapter 366 before constructing, installing,
repairing, or altering an on-site sewage disposal system in
this state for compensation.

                      SUMMARY
          A local governmental entity that has been
       designated an authorized agent for purposes
       of chapter 366 of the Health and Safety Code
       may adopt more stringent standards for on-
       site sewage disposal systems in its order or
       resolution pursuant to section 366.032(b) of
       the code.   An ~authorized agent that adopts
       more stringent standards for on-site sewage
       disposal systems pursuant to that section may
       adopt more stringent standards for local
       registration of installers if those standards
       are necessary to ensure that local installers
       will satisfy the agent's more       stringent
       disposal system standards. Thus, authorized
       agents are authorized by section 366.032(b)
       to require additional fees or training, local
       licenses or registrations, and the posting of
       surety bonds if necessary to ensure accom-
       plishment of their more stringent standards
       for on-site sewage disposal systems.    Local
       standards must not directly conflict with
       chapter 366 of the Health and Safety Code.
          Furthermore, chapter 366 of the Health and
       Safety Code does not preempt local regula-
       tions not directly in conflict with its
       requirements that are     adopted by    local
       governmental entities in accordance      with
       other legal authority.   Thus, local govern-
       mental entities, whether or not they are
       designated as authorized agents, may adopt
       more stringent requirements than the state
       for on-site sewage disposal systems and their
       installers if    they   possess   the   legal
       authority to do so and if such requirements
