If a proposed mCDR or mSRM activity, including field research trials, involves the disposition of material into marine waters, then a permit or authorization under the Marine, Protection, Research, and Sanctuaries Act (MPRSA) or the Clean Water Act may be required. Below, view information and resources related to permitting for mCDR and mSRM activities.
On this page:
The London Convention and London Protocol are two international treaties that protect the marine environment from pollution caused by the dumping of wastes and other matter into the ocean. The Marine Protection, Research and Sanctuaries Act (MPRSA) implements the requirements of the London Convention in the United States.
Depending on case-specific facts of the proposed mCDR or mSRM activity, including the specific type and location of the activity, a permit may be required under one of the following permitting programs under statutes administered by the EPA:
Regardless of the applicable statutory permitting program, the permitting process generally includes:
Unless specifically excluded or exempt from MPRSA, an MPRSA permit is needed to authorize the transportation and "dumping" of any material into "ocean waters". Section 106 of the MPRSA voids any licenses, permits, and authorizations other than MPRSA permits that purport to authorize activities regulated by the MPRSA. An MPRSA permit is not needed for activities that are specifically exempt from permitting under the MPRSA or for the disposition of material from activities that do not occur in ocean waters.
Examples of activities that do not require an MPRSA permit:
"Dumping" means a disposition of material. The MPRSA uses the term "dumping"; that term is defined broadly to encompass the disposition of material both for the purpose of disposal and purposes other than disposal. There are exemptions to the definition of dumping, including when "construction of a fixed structure or artificial island" or "placement of a device" is for a purpose other than disposal and where the construction or placement is otherwise regulated under another law.
The MPRSA applies in "ocean waters." Ocean waters include the open seas lying seaward of the "baseline" of the territorial seas. In general terms, the baseline is the mean lower low water line, or ordinary low water mark, along the coast and the "closing lines" across rivers mouths and openings of bays that are depicted on official United States Nautical Charts.
"Ocean waters" for the purposes of the MPRSA include:


An MPRSA permit would be needed by:
Examples of mCDR or mSRM activities that may require authorization under an MPRSA permit include:
MPRSA permits authorize the transportation and disposition of materials for the mCDR or mSRM activities.
Research permits are the most relevant MPRSA permit category for mCDR or mSRM research activities. However, MPRSA general or special permits may be appropriate in some situations. Research permits may be issued for a period of up to 18 months. General and special permits may be issued for up to 7 years and 3 years, respectively.
All MPRSA permits types may be considered for renewal.
The EPA encourages potential permit applicants to familiarize themselves with the requirements for MPRSA permits as described in the MPRSA regulations (40 CFR Part 220 to 229) and particularly the permit application sections (40 CFR Parts 221 and 222).
The permit application process begins with the applicant developing a permit application. Application processing fees are laid out in 40 CFR 221.5.
Once the EPA receives a complete application, permitting process described in 40 CFR Part 222 begins. This process includes coordination and/or consultation with other relevant entities as appropriate. These entities may include states, Tribes and federal agencies, including those that administer federal statues such as the Endangered Species Act, Clean Water Act 401, and Coastal Zone Management Act. The process also includes a public review and comment period.
The application requirements are set forth at 40 CFR 221.1. The MPRSA permit application includes:
Applicants should propose suitable location(s) for mCDR or mSRM research activities, which the EPA will evaluate for approval. Potential locations should be selected based upon various criteria, including:
Note that existing MPRSA ocean sites designated for the ocean disposal of dredged material are not available locations for mCDR research involving the disposition of material (40 CFR 228.4(e)(3)).
The EPA can provide additional information on the MPRSA permit application development process to potential permit applicants and answer questions about the permitting process. Please contact the EPA headquarters point of contact for MPRSA permitting for mCDR or mSRM by emailing EPAmar...@epa.gov.
In general, discharges of pollutants from point sources into waters of the United States are regulated under the Clean Water Act and require a National Pollutant Discharge Elimination System (NPDES) permit. mCDR activities that result in the discharge of effluent (e.g., alkaline solution, CO2-depleted water) through an outfall structure into ocean waters, or otherwise are exempt from the MPRSA, are regulated under the Clean Water Act by an NPDES permit that applies the ocean discharge criteria (Clean Water Act section 403) and other Clean Water Act requirements.
The facility discharging the effluent to ocean waters could be on land, a fixed structure at sea, or a facility onboard a vessel or floating craft operating in a capacity other than as a means of transportation. For example, EPA has issued NPDES permits for discharges associated with a variety of industrial activities into marine water including offshore oil and gas exploration, production and development; aquaculture; and offshore seafood processing facilities.
Additionally, mCDR activities that result in discharges inside a bay, harbor, or body of water landward of the baseline may require authorization under a Clean Water Act NPDES permit and are not subject to MPRSA permitting, as MPRSA jurisdiction does not include waters inside the baseline of the territorial sea.
Examples of mCDR activities that may require authorization under a Clean Water Act NPDES permit:

Brian,
First, I note you have cc’d the Geoengineering Google Group despite Andrew Lockley’s email pointing out that doing so for emails not relevant to that group will lead to you being barred from that group – see his email dated 22nd March.
EVERYONE SHOULD CHECK WHO ANY REPLY EMAILS ARE ADDRESSED TO BEFORE SENDING!!!
Secondly, I suspect that, as with UK legislation for dumping at sea, the MPRSA excludes any issues dealing with oil and gas from being covered by the Act as it will be covered by other legislation. The MPRSA implements the London Convention in the US and under the Convention it states that:
Article III 1(c), “Dumping does not include “The disposal of waste or other matter directly arising from, or related to the exploration, exploitation and associated off-shore processing of sea-bed mineral resources will not be covered by the provisions of this Convention.”
Best wishes
Chris.

Subject: Is it still geoengineering if one doesn't say so, and it's in the wrong direction?: [CDR] Permitting for mCDR and mSRM | US EPA
Hi Chris and all,
Thanks for your note, Chris,
As 'geoengineering' can be defined as intentionally changing our climate, and as fossil fuel extraction and sale, when such is known to change our climate, can thus be defined as geoengineering, and as fossil fuel extraction firms have long known that such changes our climate, i thence seems that such extraction within USA has violated the EPA's MPRSA since the MPRSA was established. – I don’t see that working as activities occurring outside the marine environment would not fall under the MPRSA but I am not familiar with the MPRSA in detail.
Further, Article III 1(c) as you cite, would not exempt fossil fuel extraction and sale from USA's land-based reserves, when, as is also known, the ultimate disposal site of a significant portion of this fossil fuel carbon is the sea. – Again I don’t see this working with the MPRSA. However, there have been a couple of suggestions for potential legal action under the UN Convention of the Law of the Sea – see these papers:
