The Operative Sentence is an independent reference publication. It is not affiliated with BioDrain Medical, Inc., Axe Compute Inc., DeRoyal Industries, Inc. or any manufacturer, and it sells, services and recommends nothing. This page describes what published regulations, guidelines and studies say. It is not legal advice, not clinical advice, and not a substitute for your facility’s exposure control plan, your state’s rules or your sewer authority’s ordinance. Nobody who writes these pages has worked in an operating room. This publication is not a standards body and nothing here is a standard, a guideline or a government publication.

Scope

This register covers one question and one layer of law: what a state’s own medical-waste statute or administrative code says about discharging untreated liquid blood, blood products or body fluids to a sanitary sewer. It is the second of three layers.

The first layer is federal, and it is a deferral. OSHA’s bloodborne pathogens standard has no drain provision and no sewer provision; its only disposal clause requires that disposal comply with applicable regulations of the United States, States and Territories, and political subdivisions.14 The Environmental Protection Agency has had no medical-waste authority since the Medical Waste Tracking Act expired on 21 June 1991, and its own page says medical waste is primarily regulated by state environmental and health departments.13 So the federal layer sends you to this one.

The third layer is the sewer-use ordinance of the utility that receives the discharge, and it binds independently. A generator can satisfy its state rule and still violate its publicly owned treatment works’ ordinance, because the two are drafted by different agencies for different reasons. That layer is Register B.

Not in scope here: what any particular facility may do; treated or disinfected waste routed to landfill; sharps; pathological waste; pharmaceutical sewering, which is separately prohibited for hazardous waste pharmaceuticals by 40 CFR § 266.505 and is routinely confused with blood.16

What the two clearest rules do

Read side by side, the two states whose text is least ambiguous point in opposite directions, and neither points where a reader would guess.

North Carolina runs backwards from intuition. The natural assumption is that small volumes are fine and large volumes are prohibited. North Carolina’s rule does the reverse: volumes greater than 20 millilitres in an individual container are affirmatively routed to the sanitary sewer — conditioned on notification to the local sewage treatment authority, not on a permit — with incineration or steam sterilisation offered as the alternative; volumes of 20 millilitres or less may also go to the sewer.5 The sewer is the enumerated route at both ends of the scale, and the threshold governs the paperwork, not the destination.

Ohio permits by default, and the permit is what takes the permission away. Its rule does not enumerate the sewer as one approved method among several. It grants the discharge unless a Clean Water Act permit issued to the receiving system says otherwise.2 That is the sharpest structural contrast with North Carolina anywhere in the text we have read, and it is why a national statement about “the rule” on this subject is not available to anybody.

Ohio’s sentence, and the word that is new in it

(E) A generator may discharge untreated liquid or semiliquid infectious waste consisting of exclusively blood, blood products, body fluids, and excreta into a disposal system as defined in section 6111.01 of the Revised Code unless otherwise specified in a permit for the system issued under Chapter 6111. of the Revised Code.

What it says

Discharge of untreated liquid infectious waste to a disposal system is permitted to a generator as the default position, and the thing that removes the permission is a specification in the receiving system’s own water-pollution permit. Ohio Administrative Code 3745-570-100(E), effective 6 April 2025. We enumerated all twenty-two rules in chapter 3745-570; this is the only sewer-discharge permission in the chapter, and nothing else in it qualifies this.3

What it does not say

It does not say what happens to a mixed stream. The word exclusively is new in the 2025 text — the superseded rule read “consisting of blood, blood products, body fluids, and excreta” with no such limiter — and a suction canister that holds irrigation saline alongside blood is a live question the rule does not answer. We are raising it, not resolving it. It also does not reach the receiving utility’s own sewer-use ordinance, which is a different instrument.

California’s carve-out, and the search trap in it

California’s provision is the most citable state sewer text in this register: its operative wording has been stable since 1 January 2015 and it sits as an express exception to a treat-before-disposal command.1

Cal. Health & Safety Code § 118215(b) · California Legislative Information, retrieved 2026-08-06

(b) Fluid blood or fluid blood products may be discharged to a public sewage system without treatment if its discharge is consistent with waste discharge requirements placed on the public sewage system by the California regional water quality control board with jurisdiction.

Three things about it are worth carrying away. First, the section never uses the word “sewer.” Its term is public sewage system. Anyone keyword-searching the California codes for “sewer” will conclude the state is silent, and the state is not silent. Second, the permission reaches fluid blood and fluid blood products and nothing else. It does not say “body fluids,” which is exactly what Ohio and Texas do say. A California canister holding irrigation fluid, urine or ascites is not squarely inside § 118215(b), and published summaries that render this state as permitting “body fluids” have widened the statute. Third, subdivision (b) conditions discharge only on the regional water quality control board’s waste discharge requirements, while the parallel provision for chemically disinfected laboratory waste at (c)(3) adds a second condition that (b) lacks — compliance with the requirements imposed by the owner or operator of the public sewage system. We report that asymmetry as what the text says. We do not read it as meaning a California hospital may ignore its sewer utility, because the Los Angeles city and county ordinances bind independently of the Health and Safety Code and are in Register B.

This is a survey of published law, not advice about your facility. A generator has to check its own state rule and its own publicly owned treatment works’ sewer-use ordinance. Either can be stricter than the other, both bind independently, and neither is displaced by a federal standard.

State Citation Operative text, verbatim Status Retrieved, and what qualifies it
California Cal. Health & Safety Code § 118215(b). Amended by Stats. 2014, Ch. 564, Sec. 70 (AB 333), effective 1 January 2015. (b) Fluid blood or fluid blood products may be discharged to a public sewage system without treatment if its discharge is consistent with waste discharge requirements placed on the public sewage system by the California regional water quality control board with jurisdiction. Verified Retrieved live from California Legislative Information, 2026-08-06, HTTP 200. Reaches fluid blood and fluid blood products only, not body fluids generally. The statute’s term is “public sewage system,” not “sewer.” Subdivision (b) is an express carve-out from (a)’s command to treat medical waste before disposal.
Massachusetts 105 CMR 480.200(A)(1). If the waste generator is connected to a municipal sewerage system or septic system, free draining blood and blood products, except blood saturated materials, may be disposed of directly into these systems unless such disposal is otherwise restricted by the authorized approving agency. Verified Retrieved 2026-08-06. Expressly permits free-draining blood and expressly excludes blood-saturated materials, which is the clearest state statement of that distinction we hold. Our retrieval log recorded the publisher and the date but not the address; the row rests on the transcribed clause and will gain a URL at the next review. Massachusetts also sits underneath the Boston MWRA cross-reference in Register B.
North Carolina 15A NCAC 13B .1202(i)(1) and (i)(6). Readopted effective 1 November 2019. (1) Blood and body fluids in individual containers in volumes greater than 20 milliliters shall be disposed of by sanitary sewer if the local sewage treatment authority has been notified; or treated by incineration or steam sterilization.(6) … Blood and body fluids in individual containers in volumes of 20 milliliters or less may also be disposed of in a sanitary sewer. Verified Retrieved 2026-08-06 from the North Carolina State Laboratory of Public Health posting of the 2019 medical waste rules. The structure runs backwards from intuition: above 20 mL the sewer is an affirmatively enumerated route conditioned on notification, not a permit; at or below 20 mL it is permitted as well. Anyone assuming small volumes are allowed and large volumes are banned has this state exactly backwards.
Rhode Island 250-RICR-140-15-1.15(F)(3)(a), formerly § 15.7(c)(1). (iii) Discharge into an Individual Sewage Disposal System (ISDS), provided that chemical disinfectants and/or preservatives are not added … and that no more than ten (10) gallons … are discharged in an ISDS during a twenty-four (24) hour period; Verified Retrieved 2026-08-06. The only volumetric cap on an on-site system we found in any state. Note the inversion: for the septic route the rule forbids adding chemical disinfectant, which is the opposite of the treat-first instinct. Our notes record that the same subsection expressly permits disinfection on the municipal-sewer branch; we did not transcribe that branch, so treat the inversion as our reading and not as text you can check here. Retrieval URL not recorded.
Ohio OAC 3745-27-30(C)(3). Effective 1 March 2013. Generators of infectious wastes may discharge untreated liquid or semiliquid infectious wastes consisting of blood, blood products, body fluids, and excreta into a disposal system … unless the discharge of those wastes into a disposal system is inconsistent with the terms and conditions of any permit for the system Qualified 2026-08-06Superseded 2025-04-06: renumbered to OAC 3745-570-100, effective 2025-04-06. Struck and kept rather than deleted, because this is the citation still in circulation and its live URL now returns “no rule corresponds.” Old text read from an Internet Archive raw capture dated 2025-02-09.
Ohio OAC 3745-570-100(E), “Infectious waste generators – general obligations.” Effective 6 April 2025. (E) A generator may discharge untreated liquid or semiliquid infectious waste consisting of exclusively blood, blood products, body fluids, and excreta into a disposal system as defined in section 6111.01 of the Revised Code unless otherwise specified in a permit for the system issued under Chapter 6111. of the Revised Code. Qualified Retrieved live from the Ohio Legislative Service Commission, 2026-08-06, HTTP 200; page stamped “Effective: April 6, 2025.” Qualified because the 2025 renumbering was not cosmetic. The word exclusively is new, and whether a canister holding irrigation saline as well as blood consists exclusively of the four named categories is an open question the rule does not answer. The proviso was also rewritten from “inconsistent with the terms and conditions of” a permit to “otherwise specified in” a permit, which is a lower trigger. All twenty-two rules in chapter 3745-570 were enumerated; (E) is the only sewer permission in the chapter.
Texas 25 TAC § 1.136(a)(2)(A), with the definitions at § 1.132(7) and (23). Last recorded amendment 24 May 2018, 43 TexReg 3242. Bulk human blood, bulk human blood products, and bulk human body fluids … shall be subjected to one of the following methods of treatment and disposal: (A) discharging into a sanitary sewer system;… done in accordance with provisions of local sewage discharge ordinances. Verified As of: text as published by the Texas Secretary of State and captured 2024-07-13; last recorded amendment 2018-05-24 (43 TexReg 3242). Texas retired its machine-readable Administrative Code viewer in 2025 and the replacement portal does not serve retrievable text, so we have confirmed that nothing has changed rather than read the rule as it stands today. Currency was established by sweeping 109 of 109 weekly Texas Register issues published between 2024-07-05 and 2026-08-07 — 100% coverage — for any proposed, adopted or withdrawn action on 25 TAC §§ 1.131–1.137, and finding none. Issues published before about August 2025 had to come from Internet Archive captures, because the live Texas Register archive is a rolling twelve-month window rather than an archive and returns “file not found” for anything older. Subparagraph (A) stands alone with no antecedent treatment step, unlike (B)–(J). “Bulk” is a containerised aggregate volume of 100 mL or more. DSHS still listed the subchapter as governing law on 2026-08-06.
Florida Fla. Admin. Code r. 64E-16.007(5), read against 64E-16.007(1). … liquid or semi-solid form and aerosol formation is minimal Qualified Retrieved 2026-08-06; retrieval URL not recorded. Subsection (5) authorises sewer discharge for biomedical waste in liquid or semi-solid form where the receiving system is approved and aerosol formation is minimal. Qualified because the agency’s own website contradicts its own rule: subsection (1) reads as a blanket pretreatment mandate, subsection (5) never cross-references it, and the Florida Department of Health biomedical waste program page recites (1) and never mentions (5). A generator relying on the department’s website would conclude the opposite of what the rule says. Secondary databases render (5) as “semi-liquid” and drop the aerosol clause. Chapter 64E-16 entered rule development 2026-04-01.
Washington Ch. 70A.228 RCW, recodified in full from the repealed ch. 70.95K RCW by 2020 c 20 § 2021. No provision transcribed. Not checked Opened 2026-08-06. We did not find a state-level provision on discharging blood or body fluids to a sanitary sewer, but that impression rests on a reading of the recodified chapter’s scope rather than on a keyword scan we can publish with its terms, its character count and its date, so no verdict is offered and this row is not a finding of silence. The citation trap does stand on primary text: ch. 70.95K RCW is dead, recodified in full to ch. 70A.228 RCW by 2020 c 20 § 2021, and any source still citing 70.95K is stale. See the note under Table 2.
Virginia Virginia’s regulated medical waste programme; the domestic-sewage exclusion. No provision transcribed. Not checked Opened 2026-08-06. Our reading is that the domestic-sewage exclusion removes material discharged to a sewer from the reach of the programme, so there would be no state discharge provision to quote — but that is a reading of programme scope, not a keyword scan we can publish with its terms, its character count and its date, so no verdict is offered. Recorded as a lead and not as a finding, because we hold no transcribed citation for it: Virginia is reported to exempt empty suction canisters and tubing from regulated medical waste unless the item is otherwise subject to the bloodborne pathogens standard.

Source: none. This table records the absence of a retrieval, not a document. Compiled 2026-08-06. Forty states, plus Georgia, which is out of scope and explained below; the District of Columbia and the territories are outside this register at v1.0, though DC’s sewer authority appears in Register B.

Notes on the two tables

Some of the forty have been characterised in secondary sources, and a few in our own working notes. None of them has a verdict here. Connecticut, Maryland and Pennsylvania each appear in circulating summaries with a one-line disposition, and New York, New Jersey and Illinois are named in half the surveys on this subject. We did not retrieve quotable primary text for any of them, so the rows say we have not read them and nothing else. A one-line disposition we cannot show you is the exact commodity this publication exists to replace, and printing our own would be a strange way to begin.

This register carries no Silent row, and two rows that nearly did. Washington and Virginia were opened, and in both our reading of the governing programme’s scope — Washington’s recodified chapter, Virginia’s domestic-sewage exclusion — is that no state discharge provision exists to quote. That is a reading, not a scan. Silent on this site is a claim about a keyword scan we ran ourselves and can publish with its terms, its character count and its date, of the kind we ran for the sewer authorities in Register B, and we hold no such scan for either state. So both ship Not checked and the reading stays here, in prose, labelled as a reading. We think the readings are right. A status chip is not the place to say so.

Silence is not permission. This is the point on which the published guidance is least useful. The CDC’s environmental infection control guideline gives the affirmative recommendation, at Category II — its own weakest actionable tier.15

CDC, Guidelines for Environmental Infection Control in Health-Care Facilities (2003, updated 2019), Part I § I · retrieved 2026-08-06

Sanitary sewers may be used for the safe disposal of blood, suctioned fluids, ground tissues, excretions, and secretions, provided that local sewage discharge requirements are met and that the state has declared this to be an acceptable method of disposal.

Read the last clause. The recommendation is conditioned on local sewage discharge requirements being met and on the state having declared the method acceptable. In a state that has declared nothing, there is no declaration to rely on, and the recommendation does not execute itself. We have not seen that point made in any published source, and it is why the difference between a Not checked row and a Verified row has practical teeth rather than merely bibliographic teeth.

Georgia is out of scope

Georgia is outside the scope of this register. Secondary sources repeatedly assert a Georgia sewer provision; we could not confirm one in primary text, and the databases we tried returned 403. We offer no verdict on Georgia, in either direction, and Georgia has no row in either table above. It is not silent, it is not permitting and it is not restricting, as far as anything published here is concerned — it is unread, and we would rather say that in a sentence than encode a guess as a status chip.

One thing to keep separate, because the two are constantly conflated: Georgia’s surgical smoke statute is confirmed in primary text and does have a row, in Register C. The two subjects have nothing to do with each other beyond sharing a state.

How a row here is built

A state gets a verdict when we hold the words. Every row marked Verified or Qualified carries a verbatim quotation from text we retrieved from an official publisher, pulled as raw HTML or PDF, de-tagged locally and read. A state whose text we could not retrieve ships Not checked even where we are fairly confident what it says. Silent is reserved for a keyword scan we ran ourselves and can publish with its terms, its character count and its date; no state in this register has one yet, which is why no row here carries it.

The difference between Verified and Qualified is a live caveat, not a difference in our confidence in the transcription. Ohio is qualified because it was renumbered and the new text changed. Texas is qualified because the state took its machine-readable code viewer offline and we are quoting a 2024 capture. Florida is qualified because the agency’s own website recites a different subsection than the one that governs. Each of those is a fact about the record, and each is written in the row rather than in a footnote at the bottom of the page.

What would change these rows

Where this could be wrong

The strongest objection to this register is that it is small enough to mislead by composition. Nine states out of fifty is not a survey, and the nine are not a random nine: they are the ones whose publishers let us in. States with hostile or broken code websites are systematically underrepresented here, and Texas is the visible example of what that costs: its rule is verified only because we could sweep two years of the state gazette for amendments, since its own government no longer publishes the rule itself in a form anyone can read. A reader who treats Table 1 as a sample of American practice will draw the wrong inference; the honest reading is that it is a sample of American government web infrastructure.

The second objection is the retrieval-date convention. Every row in Table 1 is dated 2026-08-06 because that is when the research pass behind this register completed. For California and Ohio we hold the HTTP status and the publisher’s own effective-date stamp, so the date means what it appears to mean. For Massachusetts, Rhode Island, Florida and Washington our log recorded the publisher and the date but not the address, and the date is therefore the date of the pass rather than a timestamp we can show you. We could have hidden that by omitting the dates. We would rather print the weaker provenance and label it.
