Could Texas local governments impose stricter septic-system installer rules, and did licensed plumbers need state installer registration?

Local septic-system standards and installer registration

Plain-English summary

Texas Attorney General Jim Mattox concluded in 1990 that a local governmental entity designated as an authorized agent under Health and Safety Code chapter 366 could adopt on-site sewage disposal standards stricter than the state's minimum standards. When necessary to enforce those stricter system standards, the agent could also impose stricter local requirements on installers.

Those local installer requirements could include added fees or training, local licensing or registration, and surety bonds. They still could not directly conflict with chapter 366.

"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."

Chapter 366 did not occupy the entire field of local septic regulation. A local government, whether or not it was an authorized agent, could use other legal authority to adopt stricter nonconflicting rules for systems and installers. The opinion stressed that the local government still needed independent authority for the rule and that direct conflicts were preempted.

"Local governmental 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 do not directly conflict with chapter 366."

The opinion also concluded that a state plumbing license did not replace installer registration under chapter 366. A plumber performing compensated construction, installation, alteration, or repair of an on-site sewage disposal system needed the state installer registration unless a statutory exemption applied.

"Individuals who hold state plumbing licenses in accordance with article 6243-101, V.T.C.S., must obtain state installer registrations as required by chapter 366 to construct, install, alter or repair on-site sewage disposal systems for compensation in this state."

Currency note

This opinion was issued in 1990. Subsequent statutory amendments, court decisions, or later AG opinions may have changed the analysis. Treat this page as historical context, not current legal advice. Verify current law before relying on any specific rule, deadline, or remedy mentioned here.

What the opinion said for affected groups in 1990

Authorized local agents

An authorized agent could adopt more protective on-site sewage standards and the installer rules necessary to make those standards effective. The opinion treated those installer powers as incidental to the express system-regulation authority.

Counties, municipalities, river authorities, and special districts

Chapter 366 set minimum statewide standards rather than occupying the entire field. Local entities could rely on other legal authority for stricter, nonconflicting regulation.

Septic-system installers

State registration remained mandatory. Local registration, fees, training, or bonding could also apply when supported by local authority and consistent with chapter 366.

Licensed plumbers

A plumbing license did not create an exemption from chapter 366 installer registration. The only cited plumbing-law exemption concerned lawn irrigation systems.

Common questions

Could an authorized agent require a local septic-installer license or registration?

Yes, if the requirement was necessary to carry out the agent's stricter on-site sewage standards and did not directly conflict with chapter 366.

Could the local government charge added fees or require training and a bond?

The opinion said those requirements could be adopted when necessary to accomplish stricter local standards. The validity of a particular requirement could depend on facts and the authority used.

Did chapter 366 prevent all local septic-system regulation outside its authorized-agent system?

No. Nonconflicting local rules could rest on other legal authority because chapter 366 did not exclusively occupy the field.

What kinds of local rules would conflict with state law?

The opinion identified less-stringent standards, rules allowing installers to avoid state registration, and duplicative fees for costs already covered by state fees as examples of possible direct conflicts.

Did a Texas plumbing license satisfy the septic-installer registration rule?

No. The opinion found no statutory exemption for licensed plumbers performing compensated on-site sewage work.

Background and legal framework

Chapter 366 recodified former article 4477-7e and established statewide regulation of on-site sewage disposal systems. Local governmental entities could become authorized agents by adopting an order or resolution, holding a hearing, and obtaining department approval.

Section 366.032(b) allowed more stringent local standards that supplied greater public-health and safety protection. Legislative history described the state rules as minimum standards and showed an expectation that local governments could continue stronger programs.

For preemption, the opinion asked whether state law expressly prohibited local regulation, exclusively occupied the field, or directly conflicted with the local rule. It concluded that chapter 366 established a floor but did not erase other lawful local authority.

THE ATTORNEY GENERAL
OF TEXAS
JIM MATTOX December 28, 1990
ATTORNEY GENERAL
Robert Bernstein, M.D. Opinion No. JM-1278
Commissioner
Texas Department of Health Re: Registration of installers
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.
   § 366.002(8). For the most part, these systems are septic

tank systems, aerobic treatment plants and other treatment
devices used by homeowners and small businesses. See
generally Tex. Engineering Extension Service, Tex. A & M
Univ. System, On-Site Sewerage Facilities 4-1 to 4-14, 6-1
to 6-12 (July 1989). Installers are persons who are compen-
sated by others to construct, install, alter or repair
on-site sewage disposal systems. Health & Safety Code
§ 366.002(5).

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 § 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
§ 366.002(1); see also id. § 366.033. For purposes of
chapter 366, the phrase "local governmental entities" refers
to municipalities, counties, river authorities or special
districts. Id. § 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 is
exclusive or that authorized agents may not impose more
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. See id. § 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 & Safety Code
§§ 366.031-.032. Designation takes effect when the
department approves the order or resolution in writing.
Id. § 366.031(b).

The order or resolution must satisfy the department’s
minimum requirements for on-site sewage disposal systems and
include a written enforcement plan. Id. § 366.032(a); see
also id. § 366.034(b) (revocation of an authorized agent’s
designation if it does not consistently enforce the minimum
requirements). More stringent requirements are permissible,

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 4477-7e, 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." Id. 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.
Id. 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, see Health &
Safety Code § 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

language in cases of conflict); Attorney General Opinion

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. Hearings on Tex. H.B. 1875 Before the
   House Comm. on Natural Resources, 70th Leg. (March 25, 1987)
   (testimonies 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, §§ 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.

local regulation or deprive entities such as counties that
were currently regulating sewage facilities or their
installers of their power to do so. See, e.g., Hearings on
Tex. H.B. 1875 Before the House Comm. on Natural Resources,
70th Leg. (March 25, 1987) (testimonies of Mark Hoelscher,
Larry Soward, Jack Purcell, R.J. King, representatives of
various state and local entities) (tapes available from
House Technical Services) .4

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.
Terrell v. Sparks, 135 S.W. 519, 521 (Tex. 1911); Austin
Road Co. v. Evans, 499 S.W.2d 194, 203 (Tex. Civ. App. -

Statutes § 118, at 701-02 (grant of express power conveys
every incidental power necessary and proper to effectuate
legislative grant). As stated earlier, no provision of
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

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. §

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, training, bonds, licenses, or registrations must
ensure compliance with the more stringent standards adopted

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

6. An agent’s more stringent system or installer
   standards must not directly conflict with the department’s
   minimum standards. See infra Note 7 and accompanying text;
   see also Attorney General Opinion JM-790 (1987) (local
   regulation preempted if in direct conflict with state law :
   that does not exclusively occupy the field).

p. 6853

Dr. Robert Bernstein - Page 7 (JM-1278)
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. See Attorney General Opinions JM-790, JM-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.
Compare Attorney General Opinion JM-1195 (1990) (express
statutory provision that local licenses not required) with
Attorney General Opinion JM-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. See supra, 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. Compare Attorney
General Opinion JM-1195 (1990) (insurance coverage required
by state law indicates legislative intent to preempt local
bond requirements) and Attorney General Opinion JM-790
(1987) (detailed state landlord and tenant law indicates
legislative intent to occupy field and preempt all local
regulation) with Attorney General Opinion JM-994 (1988)

(state authority to regulate sale of abusable glues does not
per se preempt local ordinance requiring business personnel
to assist customers in such sales) and Attorney General

p. 6854

Dr. Robert Bernstein - Page 8 (JM-1278)
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 as a restriction on or implied repeal of local powers
to promote the public health and protect the environment.
See, e.g., Hearings on Tex. H.B. 1875, supra (testimonies of
Mark Hoelscher, Wayne Farrell, Larry Soward and R.J. King).
Thus, we conclude that the legislature 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. See Health & Safety Code
§§ 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 :

id. §§ 366.051, 366.071. Furthermore, additional permit
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
"installer" 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. §§ 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. See V.T.C.S. art. 6243-101, § 2 (plumbing
includes all piping, appurtenances and appliances for the
elimination of sewage, including disposal systems); Health &
Safety Code § 366.002(8) (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, e.g., Attorney General
Opinion H-495 (1975); see also Attorney General Opinion

p. 6856

Dr. Robert Bernstein - Page 10 (JM-1278)
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
do not directly conflict with chapter 366.
Individuals who hold state plumbing
licenses in accordance with article 6243-101,

V.T.C.S., must obtain state installer regis-
trations as required by chapter 366 to con-
struct, install, alter or repair on-site
sewage disposal systems for compensation in
this state.
