Our Common Wealth 670 is an organization committed to educating the public about the impacts of militarization throughout the Mariånas.
OUR MISSION
Our Common Wealth 670’s (OCW670) mission is to protect our ancestral lands, seas and skies from irreparable damage caused by military practices and other developments that pose a threat to our health, physical environment and livelihoods by increasing awareness of current military planning and the policies that effect us the most.
OUR VISION
We envision a healthier and safer environment for our community throughout the Mariana Islands.
OUR VALUES
We are a non-partisan alliance based in the Commonwealth of the Northern Mariana Islands (CNMI) under the Alternative Zero Coalition (AZC) umbrella, which includes the Tinian Women Association, Pagan Watch, and Guardians of Gani. We stand in solidarity with Prutehi Guåhan, Hita Litekyan, Mauna Kea Hui, and Marianas for Palestine.

Deep Sea Mining Toolkit
A critical decision is unfolding now in our islands’ waters and your voice is urgently needed.
This toolkit is your clear, accessible guide to understanding the federal push for deep-sea mining in CNMI waters—what’s at stake, why Indigenous communities are sounding the alarm, and how you can help shape the future of our ocean.
Inside, you’ll find step-by-step instructions for submitting comments, powerful talking points, and curated resources that unpack the environmental, cultural, and political impacts of mining the seafloor. Whether you’re new to the issue or already engaged, this toolkit empowers you to take informed action to protect our islands and the Blue Continent.
APRIL FEATURED EVENT
Community Workshops: MITT, SEIS, & NEPA
The public is invited to take part in upcoming Community Workshops focused on the Mariana Islands Training and Testing Area (MITT) Supplemental Environmental Impact Statement (SEIS) and the NEPA public comment process. These sessions will help participants better understand environmental review, how it affects local communities, and how to submit meaningful public comments.

May 1, 2026-Today is the comment deadline for the Mariana Islands Training and Testing Study Area (MITT) Supplemental Draft Environmental Impact Statement (SEIS). This document outlines a number of critical military plans on and around the Marianas, including intensified weapons testing. It is an injustice that this comment period has not been extended given its implications for our community as we recover from Typhoon Sinlaku. We’ve submitted extensive comments and have called on the Governors of the CNMI & Guam to please extend the deadline to enable our community to prepare and respond adequately. While we remain in active recovery, this EIS and other commenting periods will move forward, silently changing our futures unless we actively keep track and stay involved! Please check out the LINK IN BIO to read our full comment. ...
May 1, 2026-Hafa Adai/Tirow! Our survey and direct support directory will be paused as we shift to a centralized system to host this directory. Our mutual aid efforts continue, with resources still being directed to families in critical need. ...
We’re working diligently to get direct support to vulnerable families who need assistance in this difficult time. We’re navigating post-typhoon recovery with you. Si Yu’us Ma’ase/Ghilisou to our partners and friends for making this collaborative effort possible to assist our community:

🟥Even as our community continues to navigate post-typhoon recovery, this comment period remains open-leaving us vulnerable to potential changes we have not had a fair opportunity to address. At this time, many in our community simply do not have the capacity to engage meaningfully in this process.
🟥We have formally requested an extension from the Governors of CNMI and Guam. In the meantime, we are canceling our upcoming workshops related to the Mariana Islands Training and Testing Study Area Supplemental Environmental Impact Statement comment period. However, we will still be submitting extensive comments on behalf of Our Common Wealth 670 by the original deadline.
🟥Please stay tuned for further updates.
...
We created a form to help track and organize requests from residents in need of urgent support. We are building a directory of links to support families directly and this will be updated regularly. This is a grassroots effort supported by individuals from Our Common Wealth 670 and Prutehi Guåhan with help from CNMI friends and family on the ground.

Informed input from residents and technical stakeholders is essential to ensure decisions reflect local knowledge, environmental priorities, and regulatory requirements.
Advance registration is required for both sessions and spaces are limited. To reserve a spot online or in-person, please visit: https://tinyurl.com/mittworkshop. Both workshops are hybrid events, available in-person and online. Lunch and snacks will be provided for free. See you there!

Frequently
Asked
Questions
Militarization is a process by which a society organizes itself for military conflict and violence. It occurs when communities begin to privilege military goals, ideals and policies over those of the people. Some consequences of militarization include: increasing weapons development, defending national interests at all costs, base building, increasing troop size, etc.
While OCW 670 recognizes the need to maintain security measures throughout the Pacific, we do not advocate for increasing militarization at the expense of people and environments. We seek to maintain the integrity of our Covenant negotiations in which the United States “will continue to recognize and respect the scarcity and special importance of land in the Northern Mariana Islands” (Article 8: Property, Section 806 in the CNMI Covenant).
We believe that increased militarization has unjustifiably resulted in the irreparable damage to our environments and our people’s health and well-being through destructive training and testing, including the use of violent weapons technologies like sonar. Left unchecked, militarization has the potential to cause further destruction throughout the Mariana Islands, eroding our ability to engage in proper self-governance. We also recognize that military policies are often enacted in our community in ways that are not in line with the health and sustainability of our people, such as when the U.S. military does not adequately comply with environmental regulations, promotes military goals at the expense of community health, ignores public input, and causes irreparable damage to the natural environment.
As the descendants and rightful owners of this land, our active participation in the protection of our homelands is often in direct conflict with destructive military plans to use the Mariana Islands, including Pagan, for destructive training and testing. Therefore, your voice, input and knowledge as a protector of the Marianas is integral to the overall goals of OCW 670 and the broader Marianas community. With the support of our diverse community, OCW 670 can bolster its capacity to serve the needs of our islands’ people.
Any person with a vested interest in the protection of the Marianas is encouraged to join OCW 670. We welcome individuals from all walks of life, from community members residing in the CNMI, to those living abroad; teachers, parents, children, man’amko, manhoben, artists, advocates and all others. OCW 670 does not discriminate on the basis of race, color, religion (creed), gender, gender expression, age, national origin (ancestry), disability, marital status, sexual orientation, or military status, in any of its activities or operations.
We encourage members to attend our re-occurring membership meetings to discuss recent events, community organizing and other important aspects related to OCW 670 goals. Our group depends on the knowledge, expertise and involvement of community members like yourself that allow us to maintain active and engaged conversations about important issues in our community. However, you are welcome to choose the level of involvement in the group that best suits your lifestyle.
Members are welcome to choose the level of involvement that works best for them. We encourage everyone to join our email list to receive monthly newsletter updates about the most urgent issues facing the Marianas, as well as notifications of upcoming OCW 670 events and educational opportunities. Those who want to play a more active role can join OCW 670’s Policy, Public Information, Logistics, Public Safety, and Environmental Health committees to get more involved in advocating for positive changes in our community.
Please see our Code of Ethics regarding OCW 670’s expectations for group members. As always, we encourage respectful dialogue with one another and with others in the community, and actively seek to express our concerns as “one voice” to promote cohesiveness and professionalism when representing OCW 670.
