Based on all the files, records and
proceedings herein, and for the reasons set forth in the accompanying
memorandum, the Administrative Law Judge makes the following:
FINDINGS OF
FACT
1.
This contested
case proceeding was initiated based upon the Respondents’ appeal of an
Administrative Penalty Order issued by the Department on February 27, 2008,
alleging that the Respondents committed certain violations of the Minnesota
plumbing laws in connection with work performed at a construction site for a
future Dollar Tree Store in International Falls, Minnesota (hereinafter the “Dollar
Tree site”). Carl Bowman (hereinafter
“Bowman”) is the chief executive officer, chief financial officer, vice
president, and a shareholder of Bowman Construction Co., Inc. (hereinafter the
“Company”).[3]
2.
The Company
entered into two subcontracts with Nations Contracting, LLC (hereinafter
“Nations”) to perform work at the Dollar Tree site. One subcontract was for concrete work,[4]
and another subcontract was for site work.[5] Bowman signed both subcontracts as the owner
of the Company.[6] Bowman and other employees of the Company
performed work at the Dollar Tree site pursuant to the two subcontracts. Bowman was personally on the site most of the
time that work was performed under the subcontracts. Bowman was in charge of the work performed by
Company employees under the subcontracts, and Bowman personally supervised the Company’s
employees in connection with their work.
The Company paid its employees for the time that they worked on the
Dollar Tree site. Bowman knew that the building to be constructed at the Dollar
Tree site was a commercial building which would be open to the public.[7]
3.
Bowman is not
licensed and has never been licensed as a plumber in
4.
The Company’s
subcontract for the site work included installation of approximately 120 linear
feet of 1.5 inch copper water line from the city connection to the building,
and approximately 110 linear feet of 6 inch sewer line from the city connection
to the building, including cleanout.[9] The installation of these lines was shown on
the construction plans for the site improvement, which were made part of the
subcontract.[10]
5.
The
superintendent of construction for Nations, Darrol Hackney, was present at the
Dollar Tree site every day that work was performed on the site by
subcontractors. Before July 30, 2007,
Hackney observed the Company’s employees, supervised by Bowman, install the
water line from the city connection near the property line to approximately
five feet from the edge of the building.
Similarly, before July 30, 2007, Hackney observed the Company’s
employees, supervised by Bowman, install the sewer line from the city
connection near the property line to within five feet of the building.[11]
6.
As Nations’
superintendent for contracting, Hackney routinely takes photographs of work
progress on construction projects.
Hackney took photographs of work performed by the Company’s employees in
connection with the water and sewer lines on the Dollar Tree site.[12]
7.
A photograph
taken by Hackney on July 29, 2007, shows an employee of the Company using glue
to install a sewer line fitting at the Dollar Tree site.[13] Bowman’s testimony that he did not recognize
this as one of his employees was not credible.
8.
On or before
July 30, 2007, Bowman informed Hackney that, if Hackney wanted the sewer and
pipe lines brought inside the building from the point five feet outside of the
building, the Company would need to hire a licensed plumber. Bowman, on behalf of the Company, and Hackney,
on behalf of Nations, signed a supplemental agreement whereby the Company would
hire a licensed plumber to install the water and sewer lines from the outside
to the inside the of the building. Nations
would pay for the work on a cost plus basis.
This supplemental agreement was signed on July 30, 2007.[14]
9.
After the
supplemental agreement was signed, Hackney observed employees of the Company,
under Bowman’s supervision, install the water and sewer lines at the Dollar
Tree site from the point five feet outside the building to a point inside the
building.[15] Hackney signed off on the sewer and water
work as complete on July 31, 2008.[16]
10.
On August 6,
2007, Department inspector Brad Jensen (Jensen) happened upon the construction
site, noticed that sewer and water lines had been installed, and noticed
problems with this work. It was apparent
to Jensen that the wrong sewer pipe had been used for the job.[17] Jensen also found out on August 6, 2007, that
the sewer and water lines had been installed without submission of plans to the
Department and without approval of plans by the Department. Portions of the sewer and water lines were buried
at that time and had not been inspected as required. Plumbing plans were subsequently submitted to
the Department on August 10, 2007 and September 4, 2007, and were approved.[18]
11.
By invoice dated
September 4, 2007, the Company billed Nations for the installation of the water
and sewer lines on the Dollar Tree site.[19]
12.
On September 25
and 26, 2007, Chuck Corrin (Corrin) was present at the Dollar Tree site. Corrin oversaw the uncovering and attempted
repair of the various water and sewer lines for the purpose of preparing for
another inspection by Jensen. These are
the only two days that Hackney observed Corrin at the site.[20]
13.
Corrin was
licensed in
14.
On September 27,
2007, Jensen returned to the Dollar Tree site to witness an air pressure test
on the water and sewer lines. The sewer
line failed the test.[22]
15.
Nations
subsequently hired another plumbing contractor to fix the problems with the
water and sewer lines and complete the work.[23]
16.
According to the
last federal census in 2000, the population of
17.
On February 27,
2008, the Department issued a Combination Administrative Penalty Order to the
Respondents for violations of Minn. Stat. § 326.40, subds. 1 and 2 (2006) and
18.
The Department
based the penalty calculation on the Minnesota Department of Health Plan for
the Use of Administrative Penalty, Cease and Desist Authority, and other
division-wide enforcement tools, dated November 14, 2002 (hereinafter the “Plan”).[27]
19.
The Plan defines
the performance of work without a required license as a serious violation.[28]
20.
The Plan defines
the failure to file a bond when required by law as a serious violation.[29]
21.
The Plan defines
the failure to secure requisite plan approval prior to commencement of an
activity as a serious violation.[30]
22.
In determining
the penalty amounts, the Department calculated a base penalty for each
violation, using the matrix in the Plan which plots the degree of potential for
harm of the violation against the degree of deviation from compliance of the
violation.[31] In considering the potential for harm and
deviation from compliance, the gravity of each violation was considered.
23.
The Department
considered the willfulness of the violations, whether there was a history of
past violations, the number of current violations, whether there was any economic
benefit gained from the violations, and whether there were any other factors as
justice may require to be considered.
After considering all of these factors, the Department determined not to
change the base penalty amount.[32]
24.
The base penalty
amount was $2,000 forgivable for the violation of Minn. Stat. § 326.40, subd. 1
(2006). The base penalty was $500
forgivable and $500 non‑forgivable for the violation of Minn. Stat. §
326.40, subd. 2 (2006). The base penalty
was $2,000 non-forgivable for the violation of Minn. R. 4215.3130.[33]
25.
The Department
made $500 penalty forgivable for violation of Minn. Stat. § 326.40, subd. 2
(2006), in order to encourage compliance with the bond filing requirement. The penalty was forgivable upon the filing of
a plumbing bond.[34]
26.
The Department
made the $2,000 penalty forgivable for the violation of Minn. Stat. § 326.40,
subd. 1 (2006) because the Department was accepting pipe layer certification
cards in lieu of a license for the installation of plumbing pipes outside.[35]
CONCLUSIONS
1.
The Minnesota
Department of Health had initial authority to enforce the Minnesota Plumbing
Code. By Department of Administration
Reorganization Order No. 193, dated April 4, 2005, the Department of Health
responsibilities in relation to plumbers were transferred to the Department of
Labor and Industry. This transfer of
authority was codified in Minn. Stat. § 326B.02, subd. 1 (2008), which became
effective May 26, 2007.[36]
2.
Included with
this transfer of authority was the responsibility to enforce the plumbing code
pursuant to the Health Enforcement Consolidation Act, Minn. Stat. §§ 144.99 to
144.993.
3.
The
Administrative Law Judge and the Commissioner of Labor and Industry have
jurisdiction over this matter pursuant to Minn. Stat. §§ 14.50, 144.99, subd.
4, 144.991 (2006), and Minn. Stat. § 326B.02, subd. 1 (2008).
4.
The Notice and
Order for Hearing and Prehearing Conference is proper in all respects and the
Department has complied with all substantive and procedural requirements of law
and rule.
5.
The statute
applicable in July 2007 stated, in pertinent part:
In any city now or
hereafter having 5,000 or more population, according to the last federal
census, and having a system of waterworks or sewerage, no person, firm, or
corporation shall engage in or work at the business of a master plumber or
journeyman plumber unless licensed to do so by the state commissioner of
health.[37]
6.
The terms
“master plumber” and “journeyman plumber” were defined as follow:
Subd. 7. Journeyman Plumber. A “journeyman plumber” is any person, other
than a master plumber, who, as a principal occupation, is engaged as an
employee of, or otherwise working under the direction of, a master plumber in
the practical installation of plumbing.
Subd. 8. Master Plumber. A “master plumber” is
any person skilled in the planning, superintending, and the practical
installation of plumbing and otherwise lawfully qualified to contract for
plumbing and installations and to conduct the business of plumbing and who is
familiar with the laws and rules governing the same.[38]
7.
Respondents’
installation of water and sewer lines at the Dollar Tree site was within the
property lines of the premises, and included installation of piping to convey
sewage to the legal point of disposal, which was the connection with the city.[39] The installation of the water and sewer lines
as performed by Respondents at the Dollar Tree site was plumbing work, and
therefore, was the business of a master or journeyman plumber for which a

Minn. Stat. §
326.40, subd. 2 (2006) requires:
Any person
contracting to do plumbing work must give bond to the state in the amount of
$25,000 for all work entered into within the state. The bond shall be for the benefit of persons
injured or suffering financial loss by reason of failure to comply with the
requirements of the plumbing code. A
bond given to the state shall be filed with the Commissioner of Health and
shall be in lieu of all other bonds to any political subdivision required for
plumbing work. The bond shall be written
by a corporate surety licensed to do business in the state.
10.
Respondents
contracted to perform plumbing work without giving to the State the bond
required in violation of Minn. Stat. § 326.40, subd. 2 (2006).
11.
Prior to the installation
by any person, corporation, or public agency, of a system of plumbing that
serves the public or that serves any considerable number of persons, or any
plumbing system that shall affect the public health in any manner, complete
plans and specifications together with any additional information that the
commissioner of health may require, shall be submitted in duplicate and
approved by the commissioner. . . . No constructions shall proceed except in
accordance with approved plans.
12.
The installation
of water and sewer pipes at the Dollar Tree site by the Respondents was part of
a plumbing system that would serve the public, that would serve a considerable
number of persons, and that would affect the public health. Respondents installed these water and sewer
lines before any plans or specifications had been submitted to the Department
and before any approval of plans by the Department. Respondents, therefore, violated Minn. R.
4715.3130 (2007).
13.
The Department
reasonably determined that Respondents’ violations of Minn. Stat. § 326.40,
subd. 1 and 2 (2006) and Minn. R. 4715.3130 (2007) were serious within the
meaning of Minn. Stat. § 144.99, subd. 4(a) (2006). In determining the penalty amount, the
Department considered all factors required by Minn. Stat. § 144.991, subd.
1(a) (2006).
14.
The ALJ may not
recommend a change in the amount of the proposed penalty unless the ALJ determines
that, based on the factors in Minn. Stat. § 144.991, subd. 1(a), the amount of
the penalty is unreasonable.[41]
15.
The amount of
the penalty assessed by the Department in the Combination Administrative
Penalty Order was not unreasonable.
16.
The corrective
action included in the Combination Administrative Penalty Order was reasonable.
17.
These
conclusions are reached for the reasons set forth in the memorandum below,
which is incorporated by reference in these conclusions.
18.
The Combination
Administrative Penalty Order is proper in all respects. In issuing the Combination Administrative
Penalty Order, the Department complied with all substantive and procedural
requirements of law.
Based
upon these conclusions, and for the reasons explained in the accompanying
memorandum, the ALJ makes the following:
RECOMMENDATION
IT IS RECOMMENDED that the Commissioner of the Department of Labor and
Industry affirm the Combination Administrative Penalty Order in all respects.

MEMORANDUM
The
ALJ has carefully considered the documentary evidence, photographs, and the credibility
of the witnesses. Simply put, if the ALJ
accepts the testimony of Mr. Bowman that neither he or his men performed
any work that could be construed as plumbing work, then, the Company prevails;
the Company would not be required to have any form of plumbing license, would
not be required to post a plumbing bond nor be required to submit proposed
plumbing work plans to the State of Minnesota. If, on the other hand, the ALJ believes the
witnesses called by the Department, the ALJ must conclude the Company violated
PERFORMING
PLUMBING WORK WITHOUT A LICENSE
It
is undisputed that the installation of the water and sewer lines at the Dollar
Tree site was plumbing work for which a license was required. The operational definitions
require a journeyman to work under the direction of a master plumber in the
practical installation of plumbing. In
comparison, a master plumber plans and manages the work of the journeyman and/or
personally engages in the practical installation of plumbing. The definitions in the plumbing code make
clear that the installation of the water and sewer lines at the Dollar Tree
site was in fact the installation of plumbing.[42]
The
underlying factual question is: who installed the water and sewer lines within
the property lines of the Dollar Tree site?
The Department asserts that this plumbing work was performed by Bowman
and Company, by its employees. The
Respondents contend that they only performed ditch digging and back filling,
and that all the plumbing installations were performed by Chuck Corrin, a master
plumber.
The
ALJ finds the documentary, photographs, and testimonial evidence supporting the
Department’s position to be more credible.
The plumbing installations can be broken down into two phases: (1) who installed the water and sewer lines
from the mains at the property line to a point approximately five feet outside
the building? (2) Who brought the water
and sewer lines inside where the building would be, from the point five feet
outside the building? On the first
question, the evidence is overwhelming that the Company contracted to perform
this water and sewer installation and that the Company, through its employees
and at the direction of Bowman, installed the water and sewer lines from the
property line to a point five feet outside the building. As to the second
question, although Bowman represented that the Company would hire a licensed
plumber to bring the lines inside the building, the weight of the evidence
shows that the Company’s employees must have performed at least some of this
plumbing work. In either case, any
performance of plumbing work by the Company without a license constitutes a
violation of the
It
is clear to the ALJ that the exhibits show that the Company contracted, under
the original site contract, to install the water and sewer lines from the city
connection up to the building, but not inside.
The original construction plan shows the installation of the water and
sewer line from the property line up to the building, and states: “The City of
International Falls will construct the sanitary sewer and water service from
the mains to the property line. The
contractor will be responsible only for installation from the property line to
the building.”[43] This is consistent with the Company’s contract
for site work, which includes the following work to be performed by the
Company: “Trench/backfill/patch approximately 120LF of 1.5 inch water line from
city to building, trench/backfill/patch approximately 110LF of 6 inch sewer
line from city to building, including clean up.”[44]
Respondents
claim that the contract did not include any water or sewer pipe installation,
but only preparing the ditches for the pipes. Respondents claim that all pipe
installation was instead included in the supplemental agreement signed on July
30, 2007 (Exhibit 6). This supplemental agreement states in pertinent part: “We
are proceeding to do extra work that you have directed us to do consisting of
the following items: . . . 2) Hire a licensed plumber to install water and
sewer line inside the building.”
Respondents’
position is not credible, for the following reasons:
1. The
supplemental agreement was not signed until July 30, 2007. Hackney took a photograph of one of the
Company’s employees working on the installation of the sewer line on July 29,
2007.[45] It is undisputed that this employee was
gluing the sewer line. This conduct
cannot be construed as merely preparing a ditch. Since the Company’s employee was installing a
sewer line before July 30, 2007, this supports the Department’s position that
the initial installation of the sewer line from the property line to a point
five feet from the building was covered under the original site work contract.
2. The original site work subcontract and
construction plan only included water and sewer line installation “to” the
building. The additional agreement, on
the other hand, refers to installation “inside the building.” Without concluding that Corrin actually did
the plumbing work, Corrin’s letter dated August 31, 2008 tends to corroborate
this as well. He states:
I (Chuck Corrin) told
the inspector that all we were going to do was water and sewer. We ran the 35# 6” sewer into the building and
so the other contractor could continue with the footings. We also ran the 11/4 type K copper into the
building then stopped. [46]
This is consistent with the
Department’s position that the supplemental agreement only covered the work
from the point five feet outside the building to the inside of the building.
3. The
site work subcontract must have covered installation of water and sewer lines,
or else the subcontract would have included the words “by others.” The site work contract included the words “by
others” in connection with the installation of the other utilities, for
example, the electrical conduit, the gas line, the telephone wire, and the
cable TV. Similarly, the site work contract
stated “including cleanout” in connection with the installation of the sewer
line.[47] If the contracted work had been merely preparation
of the ditch, the words “including cleanout” would not have been needed or used.
4. Bowman
testified that Corrin performed all of the plumbing work in ten hours, without
any help, and invoiced the Company for those ten hours of work.[48] This is not credible. It is not physically possible for an
individual to uncoil 1 ½” copper tubing alone.[49] An average plumber could not have done all
the plumbing work involved in phases one and two in that time frame by himself.
It would have taken two average plumbers
ten hours each to perform the work together.[50]
5. Although
the Company’s invoice for work at the Dollar Tree site includes six hours of
Corrin’s labor, it also includes as “services” the installation of a hardened
30 linear feet of sewer line and 130 linear feet of water line. These are separate listings for “services” in
the invoice.[51]
The Department raised an issue of the authenticity
of Exhibit B at the hearing. Accepting
that Exhibit B was a letter from Corrin, it contradicts Bowman’s testimony. Exhibit B repeatedly uses the word “we.” Bowman testified that Corrin did the work by
himself. Exhibit B clearly recognizes
that it took more than one person to do the plumbing work at the Dollar Tree
site. Accordingly, even if Corrin
performed a portion of the plumbing work, a reasonable inference from all the
evidence is that the rest of the work was performed by Company employees under
the supervision of Bowman.
CONTRACTING
FOR PLUMBING WORK WITHOUT A BOND
The
Department has shown that the Company and Bowman contracted to do plumbing work
at the Dollar Tree site. Neither the
Company nor Bowman had on file with the Department any plumbing bond,
therefore, Respondents violated Minn. Stat. § 326.40, subd. 2 (2006).
INSTALLING
PLUMBING WITHOUT PRIOR PLAN REVIEW AND APPROVAL
It
is undisputed that plumbing work was performed at the Dollar Tree site prior to
the submission of plans and specifications.
Respondents argue that it was not their responsibility to submit plans
and obtain approval. Respondents are in
error. Respondents were responsible to ensure
that plans had been submitted and approved before Respondents installed the
water and sewer lines, regardless of whom else might also be required to do
so. Under the rule, it is the installation of the plumbing without
plan approval that is the violation.
Accordingly, since Respondents installed the plumbing, they violated the
rule. Under an appropriate reading of
the rule, it is not unreasonable for the Department to penalize the “installer”
when plumbing has been installed without prior plan approval.[52]
PENALTY
AND CORRECTIVE ACTION
The
assessment of the penalty and corrective action were consistent with the
Plan. The Department reasonably
determined that the three violations were serious. Accordingly, the Department could have made
all three penalties nonforgivable. The
Department instead, chose to make half the penalty forgivable. The penalty amounts, which were consistent
with the penalty matrix in the Plan, were arrived at after consideration of all
the statutory factors. The ALJ,
therefore, cannot say that the penalty is unreasonable. The corrective action is also reasonable,
especially since the Department could legally have made the entire penalty nonforgivable.
