In brief: 126 people were sentenced for environmental offenses in the Southern District of California in fiscal years 2016 to 2025. 66 (52%) received probation only, and 56 (44%) received a prison term, with a median of 2 months. In all 94 districts, 28% of people in this category were sent to prison.
This post uses the U.S. Sentencing Commission's records of 126 people sentenced in federal court in fiscal years 2016 to 2025. Acquittals and dismissals come from a second source, the Federal Judicial Center's records of 753,808 federal defendants whose cases ended in fiscal years 2016 to 2025. It is part of the Federal Prosecution Analysis series, which builds on Military Moves Toward Sentencing Guidelines to Mirror the Federal System. How the numbers were built: How the Federal Comparison Data Was Built.
Probation Only Was the Most Common Result
66 of the 126 people (52%) received probation only, with no prison or other confinement. 56 (44%) received a prison term.
In all 94 districts, 28% were sent to prison, so the share was higher in this district. The records count only people who were convicted and sentenced.
Very Short Prison Terms
Among those sent to prison, the median prison term was 2 months. A quarter received 4.6 months or more, and a quarter received 0 months or less. The all-districts median was 5 months, and the median for all offenses in this district was 15 months.
The median was 2 months both after a guilty plea and after a trial. The trial figure rests on 2 people. These are the terms imposed, not time served.
Restitution in Most Cases
Restitution was ordered for 108 people (86%), and a fine for 19 (15%). 46 people (37%) were ordered to serve supervised release after prison, with a median term of 36 months.
A mandatory minimum prison term applied to 1 of the 126 people with that information recorded (less than 1%).
Guidelines Used in These Cases
"Environmental" is the U.S. Sentencing Commission's offense category, based on the main guideline in each case. 66 cases used §2Q1.2 (Mishandling of Hazardous or Toxic Substances or Pesticides), and 49 used §2Q2.1 (Offenses Involving Fish, Wildlife, and Plants).
7 cases used §2Q1.3 (Mishandling of Other Environmental Pollutants), and 1 used §2X3.1 (Accessory After the Fact).
Sentences Within the Guideline Range
Each case has a guideline range under the Commission's rules. 86 sentences (69%) were within it. For all offenses in this district, 15% were within the range, and for environmental cases in all districts, 50%.
22 sentences (18%) were below the range at the government's request, and 16 (13%) were below it without a government request. None was above the range.
Guilty Pleas and Criminal History
124 of the 126 people (98%) pleaded guilty, and 2 were convicted after a trial. All guilty pleas had a written plea agreement.
89% were in the lowest criminal history category, category I, and 0% were in the highest, category VI. Court-martial records have no criminal history field.
Counts by Year
30 people were sentenced in fiscal years 2016 to 2019, and 96 in fiscal years 2020 to 2025. The table shows 34 people in 2021, which is the largest yearly count, and 4 in 2016, the smallest.
Yearly medians range from 0 months to 6 months. The records cannot show what accounts for the changes. These cases were less than 1% of the 32,099 people sentenced in the district.
| Fiscal year | People sentenced | Median prison | Pleaded guilty |
|---|---|---|---|
| 2016 | 4 | 6 months | 4 of 4 |
| 2017 | 6 | n/a | 6 of 6 |
| 2018 | 13 | 6 months | 100% |
| 2019 | 7 | 0.1 months | 7 of 7 |
| 2020 | 5 | 0.4 months | 5 of 5 |
| 2021 | 34 | 0.5 months | 94% |
| 2022 | 26 | 2 months | 100% |
| 2023 | 12 | 2 months | 100% |
| 2024 | 9 | 2.1 months | 9 of 9 |
| 2025 | 10 | 0 months | 100% |
What Is Not Shown
The data gives no description of any case and no information on acquittals or dismissals. Camp Pendleton, Marine Corps Air Station Miramar, and San Diego appear in the court-martial data for this district, but courts-martial are not tried in this federal court.
How We Counted
Everyone sentenced in federal court in the Southern District of California (U.S. Sentencing Commission district label "California South") in fiscal years 2016 to 2025 whose offense type was "Environmental" (126). Offense types are the Commission's OFFGUIDE categories.
Federal fiscal years run from October 1 to September 30. No person, judge, or lawyer is identified in any of these records.
What to Keep in Mind
No parole in federal prison; credit for good conduct. Federal prison has no parole for crimes committed on or after November 1, 1987. A federal prisoner can earn up to 54 days of good conduct credit for each year of the sentence the judge imposed, which is about 15%. Some federal prisoners can also earn First Step Act time credits, but many offenses make a person ineligible. The numbers in this post are the sentences judges imposed, not the time people actually served.
Federal supervised release. Most federal prison sentences are followed by a term of supervised release that the judge sets as part of the sentence. A person who violates it can be sent back to prison. A court-martial cannot sentence anyone to supervision after release. Military parole and mandatory supervised release are decided later by a board, not by the judge at trial.
Who decides the sentence, and under what rules. Federal judges sentence every federal case. They must calculate the Sentencing Guidelines range, which is advisory, and must impose any mandatory minimum the statute requires unless an exception applies. In courts-martial, the accused could choose sentencing by members until the rules changed. For cases in which every guilty finding is for an offense committed after December 27, 2023, a military judge sentences alone, within sentencing parameters. Courts-martial tried in 2024 and later include both old-rule and new-rule cases, and the data cannot tell them apart.
Time periods. Federal numbers are by federal fiscal year (October 1 to September 30), based on the sentencing date. The military numbers are by trial date. Neither source has the date of the offense, so a change in law shows up in either data set gradually.
How life sentences and "time served" are counted. In the federal numbers, a life sentence is counted as 470 months, and any other sentence longer than 470 months is counted as just under 470 months. A sentence of "time served" is counted as one day (0.03 months). Averages are affected by these rules; medians much less.
Mandatory minimum sentences. Many federal statutes on drugs, images of child exploitation, child sex abuse, and firearms carry mandatory minimum prison terms. The UCMJ has mandatory minimums only for a few offenses (a dishonorable discharge or dismissal for rape and sexual assault, and life for premeditated murder). Federal sentences for these offenses are partly set by Congress, not by the judge.
